[Qgis-user] rpy2.robjects

[Giovanni Manghi]

Hi,

I don't know a thing about Mac, but maybe it can be still useful.

Under linux, when the python library you need is not packaged (as for
example rpy2 for ubuntu < 9.10) you can use a nice tool called "easy
install" that come with the python package "setup tools"

http://pypi.python.org/pypi/setuptools

once installed you can add python libraries with a simple command, like

sudo easy_install rpy2

(obviously referred to ubuntu linux).


cheers
