Hi,
Im trying to load the rpy libraries for ggplot 2 and importr. I'm on
Ubuntu 10.10 x64 with R packages installed using aptitude (including
r-base-dev). Ive installed the ggplot2 package using the R
package.install("ggplot2") command. I'm using the svn version of rpy2:
>>> rpy2.__version__
'2.1.0-dev'
importing problems fro 'packages' and 'ggplot2'
>>> import rpy2.robjects.lib.ggplot2 as ggplot2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named lib.ggplot2
>>> import rpy2.robjects as ro
>>> from rpy2.robjects.packages import importr
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named packages
>>> import rpy2.robjects.numpy2ri
results of installation test:
~$ python -m 'rpy2.tests'
