WinGrass: v.krige not working due to missing rpy2 pkg for MS Windows

Hello Helmut,

from version 2.12 the R executables are in a folder not scanned by rpy2, as you pointed out. The solution is edit RHOME system variable to point to the right folder (i.e. full path to R executable minus /bin/R.exe).

Sadly there is no longer support for rpy2 under Windows: ​http://rpy.sourceforge.net/rpy2/doc-2.1/html/overview.html#installation "There is currently no binaries or support for Microsoft Windows (more for lack of ressources than anything else)."

Hi,

any new news?

[aghisla]

No, I'm afraid.

rpy2 developer Laurent Gautier will work on Windows packaging only if sponsored. I know that some users managed to compile rpy2 from source on Windows - but have no fresh news.

I am open to consider a Python library for kriging, as replacement for R, if its implementation is not too low-level.

Sorry for inconvenience, Anne

I always thought one of the nice things about v.kridge is its ability to act as an example of how to write code that passes processing tools between GRASS and R, and from that perspective I'd be sorry to see the R dependency go away. It opens the door to *.

MarkusN suggested me to put a condition in the Makefile, like i.fft module does, and skip v.krige compilation if dependencies are missing.

Actually the only dependency visible at compile time is python-rpy2, that I plan to remove. In order to fix the compilation error with present codebase, I'd appreciate suggestions on how to check this Python dependency in the Makefile.

Would it make sense to make a new configuration parameter, like --with-R ?

Ideas welcome!

Many thanks, Anne

Microsoft’s Windows precompiled binaries

If available, the executable can be run; this will install the package in the default Python installation.

For few releases in the 2.0.x series, Microsoft Windows binaries were contributed by Laurent Oget from Predictix.

There is currently no binaries or support for Microsoft Windows (more for lack of ressources than anything else).

changing ticket to wontfix as rpy2's windows binaries are no longer available.

available rpy2 package in osgeo4w:

with these old packages in osgeo4w, there is still the same issue that R.dll can't be found:

reopen the ticket as: if a newer rpy2 package may be available in osgeo4w, this issue may be solved.

suggest to disable v.krige in winGRASS until upstream osgeo4w rpy2 may be updated. I'll open a ticket there.

yes.

it's still a too old rpy2 version in osgeo4w.
