Good day and thank you Vaclav,
I added R folder in the PATH environment variable but its not helping me with
my problem. Actually, manageR can be loader correctly in QGIS but when I try to
import a shapefile with the tool Import Layer from Canvas, I cannot perform
analysis on this data. It seems manageR cannot load the data which is a simple
polygon shapefile with an attribute table of strings and numbers. When I type
ls() or objects() in manageR I got the awnser character(0) which means there is
no variable loaded.
Im on Windows 7 32bit, QGIS 1.7.0 R 2.11.0 and Rpy2 2.0.3-1
Anybody have successfuly performed an analysis on a shapefile with manageR ?

Hi,
a very common source of problems with R and QGIS is not having the
"bin" folder of C:\Program Files\R-x.y in your PATH environment
variable. It is necessary and not created by R installation
automatically.
