Server path redirections

[oj]

Hi all,
I am pretty new to linux and I kind of ran into a problem executing a certain program from my account on the office server. I installed a statistics program R and it executes when I go the the it's directory. When I am in my root directory the "which R" command returns nothing and I thus connot use this program in conjuction with emacs.

Does this mean I have to change the path name? If so can anyone give me some advice on how to go about doing that? If not, does this mean that I need the server admin to install the program for it to run properly.

Thanks fir all your help.
Oj

I'm not sure if I've understood your question correctly, but if I have, the thing you're looking for is the PATH environment variable. It determines where the system looks for programs that are not given by a complete path.

To check what the PATH variable is currently set to, run the following command.

echo $PATH
