How to install rPython with R 3.1.3 on Windows?

[surmann]

How do I install rPython with R 3.1.3 on Windows OS?
An install.packages("rPython") from the austrian repo throws me the warning: "package rPython not available". The installation guide from rForge gives the same one.

Oh damn! rPython does not work on windows systems at the moment.

Hmm, at the moment it is not possible to call python via rPython on Windows OS. Sure, I could just check whether the used OS is windows and throw an error message in that case for the mpm2 generator. However, the problem is that I need to note rPyhon in the Imports section in the DESCRIPTION file. This way the installation of smoof breaks under windows, since rPython is not available. At the moment I have no clue how to solve this. In the worst-case I will outsource the mpm2 stuff to a single UNIX-only package.

My problem with this issue: I cannot use the ecr package without smoof which is not installable without rPython.

I installed rPython-win. Unfortunately, the package contains version 0.0-4.

I will tackle this problem on monday.

I moved rPython to Suggests. By default it should not be installed now. The python-dependent function should throw an error now on windows systems. Dirk, could you please check the latest build on you windows system?

I'm able to check smoof by check(".", force_suggests = FALSE). When I try to install the package by dt or from the R console directly, I get the following result:

> install(".", dependencies=c("Depends", "Imports", "LinkingTo"))

Do you have an idea? I tried R 32-bit and 64-bit.

[jakobbossek]

Oh man! Since this error is referred to the generated dynamic link library (dll) I suppose this is a problem with the c(++) stuff.

[jakobbossek]

Going to check this on a windows machine soon.

[jakobbossek]

Well, I just successfully installed the latest commit via devtools::install_github("jakobbossek/smoof") on a Windows 7 machine with R version 3.1.1. No problems occured. I will check this in the evening on my home pc with the newest R version.

[surmann]

Arg. I tried it this way and it works.
After I deleted the directories scr-* manually, a dt install works too. We should add this in dt clean.

[jakobbossek]

Ok, can I close this issue?
You should open a new issue in the dt issue tracker and describe the problem there.
