[R] how to call R in PHP

[Jeff Newmiller]

While someone around here might know about PHP (I don't h, the fact that you don't know how to call system suggests that you should be asking in a PHP help forum.

Rserve can be used for interactive sessions, but web services usually aren't designed that way, so you probably want to call R with batch arguments the same way you would call it from the command interpreter, but not actually via the command interpreter.
