r - Libraries not loading when running Rscript from PHP -


i trying run r script php.

my php file looks this:

exec("rscript fig_lollipop.r");

and r script looks this:

library('rpostgresql') #more goes code here...

i keep getting following error:

error in library("rpostgresql"):there no package called 'rpostgresql'

i have attempted searching common answers this, , think might related www-data user, i'm not sure. r script works fine when running terminal.

thanks in advance help! rc

i ran .libpaths() command in terminal, , discovered additional folder (where of relevant packages stored), compared .libpaths() command run web app. ended copying relevant packages folder listed in web app .libpaths(), , works now.

thanks "mrflick" advice! i'm newbie stuff, , thought packages installed users.
