[GRASS-dev] Connection failure from v.krige to R (Win XP)

[Jan Tošovský]

Hello Everyone,

I've tried to test new Kriging module. I've installed R tool (2.10.1) for
Win32 with packages gstat, spgrass6 and automap and also the necessary
connector rpy2. A description for setting up the rpy2 is not very clear, but
I finally placed it into C:\OSGeo4W\apps\Python25\Lib\site-packages and it
becomes visible for Grass. When v.krige was started, I got a Python version
conflict as the most recent rpy2 (2.0.8) msi installer contains its version
for Python 2.6 so I've downgraded rpy2 to 2.0.6. It helped.

However, just after invoking the Kriging module a system message appears:
'Are you sure you want to add the information in RHOME to the registry?'.
When Yes button is pressed, another message appears: 'Cannot import RHOME.
Error opening the file. There may be a disk or file system error.'

I reinstalled R from 'Program Files' to C:\R to avoid spaces in the path
(acc. to http://support.microsoft.com/kb/187316 ) but it didn't help. The
same result I got after setting the environment variable RHOME to
"C:\R\R-2.10.1".

Loading continues, but important buttons in the Kriging dialog are disabled.

A command output follows:
v.krige

When localized version is used, there are two extra lines at the beginning,
but it is not crucial I think:
During startup - Warning message:
Setting LC_CTYPE=cs_CZ failed 

>From the command log it is obvious some connection is established, but it is
not enough... Is it necessary to tune something a bit?

I use 6.5 version of Grass built from devel6 branch.
