Here’s an example of how to color your plot shapes and pch using an ifelse() statement. Ifelse() is handy as it creates an easy way to branch a function. The syntax is: ifelse(logical.condition, option1, option2). Meaning, if the logical condition is met, use option 1, otherwise do option 2. Obviously this is a simple example of when to use it, but it might be helpful.

The plot my code produces can be seen here (yours may be different based on your version of R or the random number seed you have set). I’d bet that if you run the code an infinite number of times, it will eventually look exactly like mine.
