Before The Workshop

Installation

Even if you already have R installed on your system, you really should make sure its up to date. This ensures that there are no problems due to outdated software. For more details about installing R, RStudio, and keeping everything up to date, UBC’s STAT545 page is an excellent resource.

• R
• RStudio
• Workshop Materials (zip file; unzip to Desktop)
• (Once you’ve installed R) packages “dplyr” and “ggplot2”

1. Open R (or RStudio) on your computer

2. Enter the following in the R console after the >

3. Make sure the result is [1] TRUE
   (If the result is [1] FALSE, please quit R and try the installation again)
