Hi,
Thanks for the advice but now I am getting an error which states that the R
file/script cannot be opened. Also, my shell and R script is in an
executable mode.
My code is as follows:
#!/bin/bash
DataFile="input.txt"
RProgram="Debug5.R"
outputfile="output_perl_${I}${I}"
time R --slave -f ${RProgram} --args ${DataFile} > ${outputfile}
Regards,
Ayush

Subject: Re: [R] Table or file as STDIN to the R Script
To: Ayush Raman <ayushra...@gmail.com>
av <- commandArgs(TRUE)
if(length(av) < 1) stop("Missing argument")
r <- read.table(av[1])
Then call your script as:
R --slave -f your-script.r --args the-filename-to-be-read.dat
Hope it helps
