Setting Up R for Performing Basic Statistical Analyses

Installing Main Programs

Make sure these are installed.

• R
• https://www.r-project.org/
• R Studio
• https://www.rstudio.com/

Working in an R notebook allows you to keep a copy of the code you've run and generate output you can save and share.

• R Studio - File - New File - New Notebook

R Studio Add Ins

R Studio allows for installation of add-ins. The GREA add-in which allows for the import of many types of data files into R seems like it will be useful.

(The code snippets which follow are R code insertions in an R notebook in R Studio.)


R Package Management for Specific Projects

I can never remember what packages I used after I tried something but I haven't worked on it for a while. I found keeping a list of the packages I need and letting R do the tedious work of making sure they're ready to use reduces my frustration level.
