I hope the extra detail helps, and I appreciate the responses.Īn answer for those not that familiar with Terminal and Bash.

I'm fine with removing and re-installing R if it's easiest to start from square one. Generally, I've been working in RStudio, but I'd still like to access R from the terminal and also to find where things are located. Is it possible, I only have R.app installed but not R? Perhaps that's the reason I'm getting the 'command not found' when typing 'R' into the terminal? I can locate the GUI in my applications and open it. Here is the output from 'echo $PATH': for the installation, I believe I downloaded it directly from a while ago. So, I'm running Sierra, and when I type 'r' or 'R' at the terminal, I get '-bash: R: command not found.' If I type, 'which R' in the terminal I do not get any output. Thanks for any help Edits after receiving comments Is it necessary to edit the PATH in my bash profile? If so, how do I give the correct location of R? I thought I could just type 'R' from the command line as I do with 'python', but that doesn't work. I have Rstudio and the standalone R app installed.

I've searched the web, and I'm still unclear on how to run R from the Mac terminal.
