Hi,
I made the changes suggested.
- I created a R_HOME variable in windows with value "C:\Program
Files\R\R-2.8.0"
- "import win32api" is OK in my Python installation
>From R I get:
> Sys.getenv("R_HOME")
R_HOME
"C:\\PROGRA~1\\R\\R-28~1.0"
> R.home()
[1] "C:\\PROGRA~1\\R\\R-28~1.0"
May I have to change this too?
Having made the changes suggestet I tryed to do the test of RPy2 without
success... I got:
PythonWin 2.5.1 (r251:54863, May 1 2007, 17:47:05) [MSC v.1310 32 bit
(Intel)] on win32.

>>> import rpy2.tests
Traceback (most recent call last):

raise RuntimeError("Unable to locate R.dll within %s" % R_HOME)
RuntimeError: Unable to locate R.dll within C

Anyway, thanks a lot.
