[Qgis-user] Problem with SDA4PP/Linked Statistical Display

[Volkan Kepoglu]

1. tested code:

import rpy2
import rpy2.robjects as robjects
print(rpy2.__version__)
print(robjects.r)
r = robjects.r
r.require("iplots")[0]
r.require("iplots")
r.require("iplots").r_repr()
r.require("ade4")[0]

2. I am testing the code in the ms-dos prompt with python itself, and it is
ok, the result is

C:\temp>python rpy2_iplots.py
2.0.6

Loading required package: iplots
Loading required package: rJava
Warning messages:

2: package 'rJava' was built under R version 2.9.1

Attaching package: 'ade4'


        The following object(s) are masked from package:base :

         within

Warning message:
package 'ade4' was built under R version 2.9.2

C:\temp>

Anne: ade4 package is working very well in my environment.

3. BUT, now tested with pywin32, the pythonwin is crashed.

maybe the problem is related with pywin32, not rpy2.
