Animint2 Quick Start Guide -

-
-

Introduction -

-

Welcome to the quick start guide. My goal is to introduce you to -animint2 in a way that is both brief and easy to -understand. I assume nothing except some basic familiarity with R, data -visualizations, and a little bit of statistics. Some familiarity with -the ggplot2 package is helpful but unnecessary.

-

After reading this, you’ll leave with a sense of how -animint2 works. You’ll also know how to make interactive -data visualizations, sometimes referred to as animints. For basic -animints, this quick start guide is all you’ll need. To learn how to -make more sophisticated animints, take a look at the animint2 -Manual. You may also want to take a look at the animint -gallery, which showcases how sophisticated and powerful animints can -be.

-
-
-

Datasets -

-

Some readers may want to follow along interactively. Both -animint2 and R have datasets that you may use. Access the -dataset list with data(). Alternatively, you may already -have a dataset you’d like to use to experiment with -animint2.

-

I use a custom dataset in this guide, which I’ve named -meowtrics. The data in the dataset are simulated, which is -a fancy way of saying that I forced a computer to make them up. The data -are about ten different housecats and how they’re perceived over -time.i Here’s a glimpse:

-
-head(meowtrics)
-
##   Day        Cat Coolness Cuteness               Kind
-## 1   1   Clifford     0.16     4.50 Domestic Shorthair
-## 2   1    Junebug     0.36     3.70  Domestic Longhair
-## 3   1     Muffin     0.41     0.47        Cornish Rex
-## 4   1 Teddy Bear     0.47     5.10 Domestic Shorthair
-## 5   1      Diana     0.61     9.60 Domestic Shorthair
-## 6   1      Bello     0.71     1.90 Domestic Shorthair

Anatomy of a Data Visualization -

-

Data visualizations are commonplace, and for good reason. Large -tables of data are difficult to parse. A good data visualization can -illuminate patterns that would have otherwise hard to spot. In contrast, -a poor (or deliberately misleading) data visualization can obscure even -obvious patterns. How do we design good data visualizations while -avoiding bad ones?

-

We start by understanding what data visualizations are made of and -how they’re arranged. This arrangement is often called the grammar of -graphics.ii This quick start guide won’t -teach you the grammar, and you don’t need to know it to get started with -animint2. But you should know that the syntax of -animint2—that is, the way the code is written—is modelled -on the grammar.

-

Let’s see an example. Say I want to visualize how people rate cat -cuteness over time. I want the y-axis to depict the cuteness ratings, -and the x-axis the days. I also want it to be a scatterplot. What should -I do?

-

First, if I haven’t already, I need to install -animint2:

-
-install.packages("animint2")
-

I load animint2:

- -

Next, I search for the functions that I’ll need and put them -together. First, I need ggplot(), which is like the blank -sheet of paper (or computer screen) the program draws on to make the -graph.iii To make a scatterplot, I’ll use -either geom_point() or geom_jitter(). Finally, -for the axes, I’ll need aes().

-

Then I name the graph and put it all together:

-
-cute_plot <-                    #1
-  ggplot() +                    #2
-  geom_point(                   #3
-    data = meowtrics,           #4
-    aes(x = Day, y = Cuteness)) #5
-cute_plot                       #6
-

A scatterplot about cat cuteness ratings over time. The x-axis are the days, and the y-axis the cuteness ratings. There is a lot of variance in the data, but in general cat cuteness ratings rise over time.

-

If you’re unfamiliar with the syntax, the code can get -confusing.iv Let’s go over this code -block line by line:

-
    -
  1. -I name the data visualization. Since it’s a -scatterplot about cat cuteness, I name it cute_plot. You -can name data visualizations whatever you like, but it’s best if you -name it something that will make sense to your future self. -
    2. -
  2. -Next, I call the ggplot() -function, since I’m making a data visualization. -
    3. -
  3. -Then I call geom_point(), because -I’m making a scatterplot. -
    4. -
  4. -I want to use my meowtrics -dataset to draw the points in my scatterplot, so I set -data = meowtrics. -
    5. -
  5. -aes() controls the aesthetics of -the data visualization, including axes. I place it inside -geom_point() and tell my program that the Day and Cuteness -variables are on the x- and y-axes, respectively. -
    6. -
  6. -I repeat the name of my data visualization, -which tells the program to display my graph. -
    7. -
-

Look at the plot. We can see that while there’s a lot of variance in -the data, there seems to be an upward trend in cat cuteness ratings. But -this graph could be better. And animint2 gives us the tools -to improve it.

-

Take a look at this slightly modified data visualization:

-
-cute_plot_colored <-                             #1
-  ggplot() +
-  geom_point(
-    data = meowtrics,
-    aes(x = Day, y = Cuteness,
-        group = Cat, color = Cat)) +             #2
-  labs(title = "Cat Cuteness Ratings Over Time") #3
-cute_plot_colored
-

A scatterplot titled Cat Cutness Ratings Over Time. It looks exactly the same as the previous graph, except all the data points are differentiated by color. There is also a legend that maps each color to a cat.

-

Each cat is differentiated from one another by color, and there’s now -a legend. Codewise, what’s changed?

-
    -
  1. -This data visualization has a different name. -If two plots have the same name, one will override the other. -
    2. -
  2. -I’ve added new arguments to -aes(): I’ve grouped the points in the scatterplot by cat, -and I’ve also differentiated the cats’ data points by -color.v -
    3. -
  3. -Using labs(), I’ve given the -graph a title. -
    4. -
-

While this new graph communicates more information, it’s also -somewhat overwhelming. What if we could move some of the data out of the -way? Or compare a subset of cat cuteness ratings instead of seeing -everything at once? Reader, I have good news.

-
-
-

Making Animints -

-

The good news is this: animint2 makes it easy to render -a static data visualization interactive. Just use the -animint() function with the previous plot as the -argument:

-
-animint(cute_plot_colored)
- -

-

-
- -
-

This is an animint of our second static data visualization. By -clicking on the legend or by using the selection menu, you can control -which subjects have their data graphed, as well as how -many.vi This allows you to explore your -data without needing to facet all possible cat combinations. For -exploratory data analysis, this level of control may be all you -need.

-

In some cases, you may want more control. Say you want to emphasize -Archibald and Muffin’s cuteness ratings over time. In -animint2, you would use the first argument and -specify which cats to present:

-
-cute_present <- 
-  animint(cute_plot_colored, 
-          first = list( #1
-            Cat = c(    #2
-              "Archibald", "Muffin")))
-cute_present
-

-

-
- -
-

This is most useful for situations where you’re showcasing or -presenting your animint. Pay attention to the syntax:

-
    -
  1. -The first argument only accepts -list()s. -
    2. -
  2. -The specified cats must be in a character -vector. That’s why they’re in a c() function. -
    3. -
-
-
-

Using showSelected -

-

Our current animints use three variables: Day, Cuteness, and Cat. -What if you want to explore or present a -fourth?vii In a static data -visualization, this would require multiple graphs or the addition of an -unwieldy third dimension.

-

Luckily, animints are not subject to the same restrictions. In -animint(), we can use the showSelected and -time arguments to show how the Coolness and Cuteness -variables interact day-by-day.

-

First, let’s look at an animint with the showSelected -variable:

-
-associations <- 
-  ggplot() +
-  geom_point(
-    data = meowtrics,
-    showSelected = "Day",           #1
-    aes(x = Coolness, y = Cuteness, 
-        color = Cat, group = Cat, 
-        key = Cat)) +               #2
-  labs(title = "Associations Between Cuteness and Coolness")
-animint(associations)
-

-

-
- -
-
    -
  1. -showSelected = "Day" lets you -adjust the day in the selection menu. -
    2. -
  2. -Most real-world datasets have missing values. -key accounts for that when transitioning between different -days. -
    3. -
-

You can use the selection menu to see the different associations -between cuteness and coolness ratings per -day.viii

-

Next, let’s see that same animint with the time and -duration options applied:

-
-animated_associations <- 
-  animint(associations, 
-          duration = list(Day = 1000), #1
-          time = list(                 #2
-            variable = "Day", 
-            ms = 1000))                #3
-animated_associations
-

-

-
- -
-
    -
  1. -duration specifies how quickly -the points move from their old location to their new -location.ix The shorter the duration, the -quicker the movement. It takes a list and uses milliseconds as its unit -of measurement. -
    2. -
  2. -time also takes a list. -
    3. -
  3. -In contrast to duration, -time = list(ms) specifies how long the points stay in -place. It also uses milliseconds as its unit of measurement. -
    4. -
-

You can also click the “Show animation controls” button and manually -adjust both the time and duration. Try it -out.

-
-
-

Using clickSelects -

-

So far, we’ve been interacting with animints by clicking the legend -and using the selection menus and animation controls. What if we could -interact with the animint directly? Using clickSelects, we -can do just that. Let’s return to our data visualization depicting -cuteness ratings over time, this time as an animint:

-
-cute_colored_again <-
-  ggplot() +
-  geom_point(
-    data = meowtrics,
-    clickSelects = "Cat", #1
-    aes(x = Day, y = Cuteness,
-        group = Cat, color = Cat))
-animint(cute_colored_again)
-

-

-
- -
-
  1. -clickSelects takes a variable -with quotations. The variable in clickSelects and -group are the same: they’re both Cat. -
-

Hover over and click on the data points. You’ll notice that it has -the same effect as clicking on the legend: It removes the data from the -animint.

-

Now, let’s interact with a very similar animint:

- -
-cute_plot_kind <-
-  ggplot() +
-  geom_point(
-    data = meowtrics,
-    clickSelects = "Kind", #1
-    aes(x = Day, y = Cuteness,
-        group = Cat, color = Cat))
-animint(cute_plot_kind)
-

-

-
- -
-
  1. -I’ve swapped out Cat for Kind. Now the -variables in clickSelects and group are -different. This is a useful way of adding another variable to your data -visualizations. -
-

When you interact with this animint, you’ll notice three -differences:

-
    -
  1. Hover over the animints. In both, you’ll notice a hover box appear. -In the first animint, the hover box repeats the cat’s name. In the -second, the hover box describes what kind of cat they are.
    2. -
  2. In the second animint, there is an additional variable in the -selection menu. You can use it to highlight the data points depicting a -certain kind of cat.
    3. -
  3. When you click on a data point, it doesn’t disappear. Instead, like -the selection menu, it highlights data points depicting certain kinds of -cats.
    4. -
-
-
-

Linked Plots -

-

animint2 also allows us to link multiple plots together -into one animint. When two plots are linked, a change in one plot can -cause changes in another.

-

Let’s return to two interactive data visualizations we’ve already -looked at: associations between coolness and cuteness, and cuteness -ratings over time.

-

Here’s the first data visualization again, lightly altered:

-
-associations_again <-
-  ggplot() +
-  geom_point(
-    data = meowtrics,
-    showSelected = "Day",
-    clickSelects = "Kind",
-    aes(x = Coolness, y = Cuteness,
-        color = Cat, group = Cat,
-        key = Cat))
-

I want to link it to my plot about cuteness ratings over time. That -way, I can see how coolness ratings change over time, too. The linking -process is a little more involved than usual:

-
-md <- data.frame(Day = unique(meowtrics$Day))  #1
-
-linked <- animint(associations_again,          #2
-                  duration = list(Day = 1000)) #3
-
-linked$overtime <-                             #4
-  ggplot() + 
-  geom_tallrect(                               #5
-    data = md,                                 #6
-    aes(xmin = Day-0.5, xmax = Day+0.5),       #7
-    clickSelects = "Day",                      #8
-    alpha = 0.5                                #9
-    ) +                                        #10
-  geom_point(
-    data = meowtrics,                          #11
-    clickSelects = "Cat",
-    aes(x = Day, y = Cuteness, 
-        group = Cat, color = Cat))
-linked                                         #12
-

-

-
- -
-
    -
  1. -I’m taking the Day column from -meowtrics (meowtrics$Day), stripping redundant -days from it viaunique(), renaming it, and then making it a -data.frame(). Now I have a dataframe of all 30 days in -meowtrics. This is for geom_tallrect(), which -I’ll use later. -
    2. -
  2. -I take associations_2 and make it -an animint. -
    3. -
  3. -duration controls how long it -takes data points to move from one part of the animint to another. As -mentioned, it’s optional. -
    4. -
  4. -I take the previously-created animint and -attach new animints to it. I name the list of animint -overtime. -
    5. -
  5. -This is the geom_tallrect() -function. It creates a vertical bar that allows you to manipulate time -variables by clicking on the plot. -
    6. -
  6. -geom_tallrect() requires a new -dataset that contains only the time variable. It’s using the dataset -that I constructed earlier. -
    7. -
  7. -xmin and xmax -control how wide the tallrect is, which affects the appearance of the -selected time variable. In this case, it controls how much a day takes -up on the tallrect. -
    8. -
  8. -clickSelects is necessary here, -since we need to be able to select the day from the plot. -
    9. -
  9. -alpha controls the transparency -of the tallrect. Lower numbers increase transparency. -
    10. -
  10. -Using +, I attach the tallrect to -the plot about cuteness ratings over time. -
    11. -
  11. -We’re back to using meowtrics as -our dataset. -
    12. -
  12. -Finally, we intitate the animint. -
    13. -
-

Try it out. When you adjust the day on the bottom plot, the top plot -also readjusts. When you click on the legend on the top plot, the bottom -plot is also affected. These linked plots can get much complex. For -examples, see the animint -gallery.

-
-
-

Conclusion -

-

And that’s it. You’re now a reasonably competent -animint2 user. If you would like to learn more, please read -the animint2 -Manual—especially chapters 1 to 4, which go over the same material -in greater depth.
