R Workshop for the Ohio Program Evaluators' Group

These are materials from an online workshop introducing R to the Ohio Program Evaluators' Group. The focus was on the fundamentals of R & Rstudio, importing and cleaning data, frequencies and other descriptive statistics, and simple visualizations with {ggplot2}.

You should have first installed R (from here) and then installed RStudio Desktop (from here). Launch RStudio once it finishes installing and you should be good to go.

If you are not comfortable with installing software on your own computer and often need help for any software installation or software updates, please go to RStudio Cloud here and create a free account. Make sure you remember the userid and password you chose. Even better, let your browser save your userid and password.
