Running R script from php webpage

I am trying to build a php file that allows users to run a R script so they don't need to open a session in the server, just to open a browser.

Usual bash from the script run fine (say echo "something", copy and move data files,...) but R script is not running. R is called with Rscript

Rscript --no-save --no-restore --verbose ./RAMS-mapa-onades-zones-manual.R > outputFile.Rout 2>&1

R output gives this error

running
  '/usr/lib/R/bin/R --slave --no-restore --no-save --no-restore'

Error in library("rgdal") : there is no package called 'rgdal'
Execution halted

Well, library(rgdal) is the first line of the R script. Rgdal is present on the R installation and the script runs fine (Rscript myscript.R) from the command line.

As starting from php, the user running R is www-data while on the terminal the user is meteo. It seems to me that some environment variable needs to be set in the php Rscript execution but I can't find the way to do it.

Any idea? Thanks in advance

Seems we've found the root cause in comments. The library paths don't match, but you can make them match by the lib.loc parameter to library(). Like this:

library(rgdal, lib.loc = c("/home/meteo/R/i686-pc-linux-gnu-library/3.1", "/usr/local/lib/R/site-library", "/usr/lib/R/library"))
