R help - Jun 2011 - sink() and library() calls cause script to stop when called from php

Hello all, 


I have a php script that makes a call 


system(PATH_PROJECT_ROOT . '/sh/combineDays.sh ' . $dateString . "
" . PATH_PROJECT_ROOT);


and within combineDays.sh I run an R script: 


R --slave --vanilla --args $testDates $BASEDIR $defaultSearchVersion <
$BASEDIR"R/combineDays.R"


At the end of this R script, I try to write results to a file, but the script
seems to stop executing after I call sink(results.file) in the R script. I
previously observed similar behavior when trying to call library() from within
the same R script.


When I run combineDays.sh from the shell, everything works fine. 


Any ideas? 


Thanks.

chmod 777 on the destination folder fixed the sink() issue. Still don't know
why library() was causing the script to stop though.
