In this course, you’ll learn to use the free, open-source statistical software R. Using R directly requires a bit of programming, so we’ll take advantage of the free, open-source program R Studio, which provides a convenient interface to R.
Here’s what you need to do by 8 a.m.,
Friday, January 20th Monday, January 23rd:
