No change in behavior. I've simplifed my python script and added the
import rpy2.rinterface as instructed. I've stopped and started the
apache server as appropriate voodoo.
Seems to me if I can't execute the library() call then it makes sense
that R functionality in the non-base libraries won't be available.
Other info: I'm running on Unbuntu Gusty ... I couldn't find a packaged
shared libraries version of R so I built it myself. I did have R
installed previously using the Synaptic package manager and subsequently
deinstalled when I built the shared library version. I've just confirmed
that Synatpic indicates that R is not installed. I notice that if I do a
printenv in a shell, there's no R_HOME variable defined. Should there
be? I recall having to futz with this when I was trying to install the
RSPython extension...the builds kept failing because R_HOME was point to
the wrong place.
I'm happy to run other tests if you tell me what to do.
