R help - Sep 2007 - capture.out(system())?

Hi,

I am trying to capture the console output of program I
call via system() but that always returns only
character(0).

For example:
capture.output(system("pdflatex out.tex") )

will yield:
character(0)

and the output still written to the R console.

Is there a command for intercepting this output?

Thank you!
  Werner

Thank you very much, Professor Ripley!
I am using Windows 2000 and the "intern=T" argument of
system() did exactly what I needed: Now system()
returns the output of the external program as an
object.

Thanks again,
  Werner
