using RCall changes Pkg.dir() on Windows about rcall.jl HOT 7 CLOSED

Does that fix it?

from rcall.jl.

At present, that check-in did not change the behavior on my machine. The following were the steps I performed to test this check-in on my existing machine image (I will also set up a fresh operating system image and Julia installation as well):

• Deleted the "RCall" folder from both the C:\Users\<username>\.julia\v0.4 and C:\Users\<username>\.julia\.cache directories.
• Launched Julia v0.4-pre build
• Performed a Pkg.update()
• Performed a Pkg.checkout("RCall")
• Closed Julia
• Launched Julia again
• Performed a Pkg.dir() operation as above
• Performed a using RCall operation as above
• Performed a second Pkg.dir() operation as above

The returned directories for each of the Pkg.dir() operations are currently the same as shown above, with the second call having the modified directory.

from rcall.jl.

Sorry, can you try:

Pkg.checkout("RCall","master")
Pkg.build("RCall")

from rcall.jl.

In performing the following:

• installed a new 32-bit Windows 8.1 VM
• installed a Julia v0.4.0-rc1 build
• installed R from CRAN
• Manually added "C:\Program Files\R\R-3.2.2\bin" to the system's Path environment variable.
• launched Julia
• Pkg.add("RCall")
• Pkg.checkout("RCall","master")
• Pkg.build("RCall")
• restarted Julia
• Pkg.dir()
• using RCall
• Pkg.dir()

the output from the two calls to Pkg.dir() provided the correct location of C:\Users\<username>\.julia\v0.4

Thanks for the fix.

Great. Once I tag a release we should be able to get rid of some of those steps...

You also shouldn't have to manually modify the PATH variable (the build process looks up the windows registry to find the installation path).

from rcall.jl.

I tried executing using RCall before having set the PATH variable and an error was thrown due to not finding the R.dll. After adding the directory containing R.exe and Rscript.exe to the PATH, the above steps worked as hoped. I will repeat the installation steps without having manually modified the PATH to test again.

Hmm, I see. You may have to close and reopen Julia before running Pkg.build?

I'll see what I can do to make the steps easier.
