This is a list of commands and their contexts for getting started with using R. R is a free programming language for statistical computing and graphics. To download R, visit cran and find the location closest to you. Then, follow the instructions based on your operating system. Many people who use R like the program RStudio, which has a console and interface for using R. That can be downloaded for free under an open source license from the RStudio website. A number of cheatsheets for common R packages have been created as a handy reference.
Using R
R can be loaded from the command line with R. Easy enough. If you remember,
in Unix there is a $ to tell you you’re at the command line.
For R’s internal command line, that symbol is >.
To clear the console in R or RStudio on a Windows or Linux operating system,
use Cntrl+L. On a Mac, you can use either Cntrl+L or Command+Option+L.
