## R CMD not recognized at command-line

 Hi, I am trying to run a batch command on Windows XP and R CMD is not recognized. I get the error, "'R' is not recognized as an internal or external command, operable program or batch file." I have "C:\Program Files\R\rw2010\bin" in my \$PATH variable and Rcmd.exe has been installed in that folder. I have restarted the computer to make sure any changes in the \$PATH variable registered. I have tried directly calling Rcmd.exe or R.exe. None of this had any effect and I can't think what I'm forgetting. In Cygwin,  I can get around this by explicitly giving the path at the prompt line, for example,  > ~/Program\ Files/R/rw2010/bin/R CMD --help This work-around does not seem work from the usual DOS Command Prompt, but I rarely use DOS commands so I may be missing something in syntax. Similarly, if I want to run several successive input files with a .bat file, this work-around won't work as a line in the .bat file. I have two questions: 1) how can I make the computer recognize R so I can just type R CMD at the prompt 2) what is a work-around like I did in cygwin that will work in a .bat file or the standard command-line prompt so that you don't have to change the path variable? (often students do not have permission to add the R folder to the path variable of a networked computer, so I'd like to know an alternative if someone asks me) Thanks, Elizabeth Purdom ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
