it gives me a
R is the name of the program I try to call. (but R is in the path, I don't know why I obtain this error)
If I change to the complete path
echo shell_exec('/usr/local/bin/R blablabla')
then I obtain:
***glibc detected***/usr/local/lib/R/bin/exec/R: double free or corruption (!prev)
and I haven't got any idea about what this error wants to say... any help? thanks!!
