Hello everyone,
I am trying to make Rpy2 work with my current installation of Python and R. I
am encountering some problems. My current version of Python is the following:
> Python 2.6.4 (r264:75706, Mar 4 2010, 10:54:36)
> [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
I built R 2.10.1 using the following commands:
$ ./configure --enable-R-shlib
$ make
I installed rpy2-2.1.0beta2 after several unsuccessful trials by using these
commands:
$ python setup.py build --r-home /home/username/R/R-2.10.1
$ python setup.py install --prefix=/home/username/src/
The following error is reported when I import rpy2:
In [1]: import rpy2.robjects.tests
Error in grep("(_US|_CA)", lcpaper) :
9 arguments passed to .Internal(grep) which requires 8
Error in .Internal(grepl(as.character(pattern), x, ignore.case, extended, :
no internal function "grepl"
Error in .Internal(grepl(as.character(pattern), x, ignore.case, extended, :
no internal function "grepl"

Any help greatly appreciated !
