my script is
<?php
...
exec("R CMD BATCH --silent /home/marcello/R_in/myfile.bat /home/marcello/R_out/myfile.out");
...
?>
This script execute in R batch mode and write the myfile.out.
On Win2000 the similar script is ok, but on linux I've a problem.
I suppose is a permession problem because the same script on shell run fine
and on Zend debugger (my IDE for php) is also ok.
In this case the owner is "marcello" , if I run the script by browser the owner is "apache".
I've overwritted all the ownerships of R directory and bin to apache user but not work.
If a run
exec("ls > mydir.txt"); is ok (is not a PHP general problem!)Someone can help me?
Thanks (and excuse my for my poor english)
