Installation of R
For detailed information on how to install R, please refer to the R documentation, linked at the beginning of this topic.
Installation under Linux (Fedora Core 4):
> yum install R
Installation under Windows:
Download and execute the installer of R (e.g. R-2.2.0-win32.exe)
Please make sure, that the program folder of the R executable is placed in the path system variable, so that it may be directly executed, without specifying the program folder. Under Linux (and all other operating systems besides Windows), the R executable will be called by VANTED, under Windows the command Rcmd will be used.
