you've reminded me i should take a closer look at R, thanks for the link. you've also shown me how easy it is to break in to your system :(

please untaint all user input in cgi scripts. you've opened the door to your system, as arbitrary commands can now be passed directly, as long as they don't include '\r' or '<-'.

you can look at Ovid's http://users.easystreet.com/ovid/cgi_course for a good web security tutorial, and Super Search around here on words like 'taint' for more on this important subject.
