R help - Apr 2011 - Runing perl script from R

Hi. I am trying to run perl script from R. Here's what happens.
> setwd("C:\\Terri\\perl")
> getwd()
[1] "C:/Terri/perl"
> list.files()
[1] "hello.pl"      "lines1_10.txt" "try_my.pl"   
"try_my.txt"
> system("hello.pl")
Warning message:
In system("hello.pl") : Impossible to run C:\Terri\perl\hello.pl

Does anyone know what I am doing wrong?

Thanks!

Terri

Perl scripts are not generally executable on their own.  The shell will 
automatically run something like "perl hello.pl", but you went to a 
lower level.

To get what you want in Windows, try

shell('hello.pl') # Windows only

or

system('perl hello.pl')
