Re: [NTG-context] Difficulties using the r module

\def\runR {\executesystemcommand{texmfstart --ifchanged=\Rfile\space --direct R CMD BATCH "-q --save --restore \Rfile\space \Rfile.out"}} or some such, I do not really understand the quoting. The invocation should change, options should not and redirectors should go away. Not sure if this is better or worse in any way. Johan 2006/7/2, Hans Hagen :

Hi Hans,

one problem could be that R has this piping; i wonder why a program that takes a 50 meg installation does not support something --output or i must have missed something

R does support redirecting output to a file. Use

R CMD BATCH [options] <infile> <outfile>

currently we use:

\def\runR {\executesystemcommand{texmfstart --ifchanged=\Rfile\space --direct R "-q --save --restore < \Rfile\space > \Rfile.out"}}

so how should it look then?

Hans
