Thanks! That's what I was wanted to know. Also, is there a similar way I can do read.table from a pipe?
For example, if there is a command that I am running to generate the datasource, I want to read that data as it comes.. Thanks... -----Original Message----- From: Aaron J.

I think the original poster wanted to read data from stdin, not execute an entire script from stdin; this works on many UNIX-like systems: d <- read.table("/dev/stdin", header=F); Otherwise, for code, you can simply pipe (or redirect) to R from the shell: % R --vanilla --slave < input > outfile -Aaron On Jul 9, 2004, at 4:34 PM, Tony Plate wrote: > The easiest way would probably be to do the hack of creating a > temporary file to hold stdin, then call R to process that file.
