[Qgis-user] rpy2.robjects

[gustavocanale at pop.com.br]

Hi everybody, 
I am a newcomer to R, Qgis and Mac, so I have a long
way to go to understand Python, Xcode, Terminal, etc..
I tried to
install SDA4PP 0.125 (Spatial Data Analysis for Point Pattern with R) to
run Home Range Analysis (specifically Kernel analysis) but it failed
because rpy2.robjects was missing. I tried to install it and couldn't find
it. 
When I try to run Home Range Analysis (Kernell adusted h) I
received the following message in Python console:

An error has
occured while executing Python code:

Traceback (most recent
call last):

Could you let me know what to do?
I guess I should install Rpy2 but I couldn't find a working link, and
also I don't know if I just have to install it in Utilities in Mac.
Many tks
Gustavo
