This program is a sample to use R and ctc as a web application.
Standard setup:
put ctc.php in your public_html directory
check that webserver user (apache, or www) is able
to write in public_html (chmod 'a+w' ~/public_html)
Change global variable R_BIN below
That's all.
Example working:
http://bioinfo.genopole-toulouse.prd.fr/~lucas/ctc.php
