Software: Learn R

Resources to learn and use the Open Source Statistical software R (R-Project)

The R Project for Statistical Computing is a free, open source statistical computing language that is popular among researchers in many fields. 

The learning curve for true understanding is steep, but specific tasks (e.g., importing files from other statistical software) are often quite easy because of packages that can be created by anybody. R undergoes rapid development and improvement. Tutorials even a year old may be out of date

NOTE: RStudio is currently in the process of changing names to Posit. Various tutorials may reference one or the other, but both are acceptable at this time.

Getting Started

The following are from the interactive Setup Tutorial:

OR see videos of the whole process for Video Installing R on  Windows or Video installing R on  Mac (From OpenIntro on YouTube)
