Hi Shalini Your best bet is to use R vanilla in the command line and a script with the commands you need that will be read by R and executed. I believe that there might be other ways but this is fairly simple to develop. Take a look on the link below regarding a discussion of similar features on the R list. http://tolstoy.newcastle.edu.au/R/devel/05/09/2448.html HTH Paulo _____ From: biodevelopers-bounces+pnuin=terra.com.br at bioinformatics.org [mailto:biodevelopers-bounces+pnuin=terra.com.br at bioinformatics.org] On Behalf Of Shalini Sridhar Sent: August 3, 2006 6:42 AM To: biodevelopers at bioinformatics.org Subject: [Biodevelopers] Running R from Unix Command Line Hello all, If someone can please throw a light on this I would be eternally greatful : I have a CGI PERL Script that needs to invoke the R program on the command line of UNIX and send commands to it. Can I do this using the normal system command? Would this work? If so, how can I specify the commands without clashing with the double quotes of perl and that of R? If not, could someone please suggest an alternative to this ? Thanks Shalini <http://www.flamingtext.com/hmail.html> Image by FlamingText.com _____ -------------- next part --------------
