Hello all,
I tried to find my answer in the archives of this mailing list, on Google and on
RPY website, but I've found nothing so far. So forgive me if this was already
asked or dumb question.
I'm trying to load a data set from MASS library, birthwt with the following code
import rpy2.robjects as robjects
r = robjects.r
r.library('MASS')
r.attach('birthwt')
However I have the following error :
Error in function (what, pos = 2, name = deparse(substitute(what)),
warn.conflicts = TRUE) :
file 'birthwt' not found
Traceback (most recent call last):
File "/home/xatre/workspace/FrameWork/src/birth.py", line 10, in ?
r.attach('birthwt')
File "/usr/lib64/python2.4/site-packages/rpy2/robjects/__init__.py", line 422,
in __call__
res = super(RFunction, self).__call__(*new_args, **new_kwargs)
rinterface.RRuntimeError: Error in function (what, pos = 2, name =
deparse(substitute(what)), warn.conflicts = TRUE) :
file 'birthwt' not found
It seems that my rpy2's "R instance" can't load or find the data set. Is this a
known issue ? How can I make rpy2's "R instance" find it, because my R can
load it. Do I need to move my data set in my folder where my .py is lunched ?
