Issue : in importr env = _get_namespace(rname) RRuntimeError

Issue #390 closed
gordon created an issue

Hi Laurent,

I am trying to solve an issue about this lien : egcm = importr('egcm')

rpy2 works fine in Spyder but I can't import the R package using : egcm = importr('egcm')

My error is :

File "C:\Users\My Name\Anaconda3\lib\site-packages\rpy2\robjects\", line 453, in importr env = _get_namespace(rname) RRuntimeError

It does not work either for "from rpy2.robjects.lib import ggplot2", same error.

I have done what you recommended here : HERE and here : HERE

I have Python 3.5.2 |Anaconda 4.2.0 (64-bit)|

Thanks in advance for your help, Best

    By changing my R_USER from this C:\Users\"your user name"\Anaconda\Lib\site-packages\rpy2

    to this : R_USER C:\Users\"your user name" I can now use importr for several packages that did not work previously such as urca.

    But the package I need; "egcm" still does not work... and I have the same error message

    Unfortunately I am unable to help much when it comes to combos involving Windows (unsupported) and IDEs I am not familiar with (here Spyder).

    I try to use rpy2 in Spyder. I have Python 3.5.2 |Anaconda 4.2.0 (64-bit).

    First, this works : import rpy2.robjects as robjects pi = robjects.r['pi'] But when I want to use importr to get a package, I have an error message. example : egcm = importr('egcm')

    My error is :

    File "C:\Users\My_Name\Anaconda3\lib\site-packages\rpy2\robjects\", line 453, in importr env = _get_namespace(rname) RRuntimeError

    It does not work either for any other R package. The package egcm works in R.

    Moreover, when I try to test rpy2 in the command line with the follownig line : python -m rpy2.tests I got the following error message:

    enter image description here


    In R : R.home()

    1 "C:/PROGRA~1/R/R-33~1.2"

    In R : .libPaths()

    1 "C:/Users/Alexandre/Documents/R/win-library/3.3" [2] "C:/Program Files/R/R-3.3.2/library"

    In Python : from rpy2.robjects.packages import importr base = importr('base') print(base.R_home())

    1 "C:/Program Files/R/R-3.3.2"

    Then I tried again :

    `conda install --channel rpy2`

    Result : All requested packages already installed. packages in environment at C:\users\Alexandre\Anaconda3:

    rpy2 2.8.2 py35r3.3.1_1 r


    `pip install rpy2 `

    Result : Requirment already satisfied (use --upgrade to upgrade): rpy2 in C:...lib\site-packages

    same line with "six" instead of "rpy2"

    then You are using pip version 8.1.2, however version 9.0.1 is available. then

    `python -m pip install --upgrade pip `

    and now it works perfectly, I have no idea why...

    Thanks in advance for any ideas !

    That's with using Windows (unsupported) andconda (third-party software managing binaries). I believe that this would be better answered by the conda community or conda support.

    Reopen if believed to be an issue with rpy2 itself.

    If Windows is completely unsupported, why does it not say that in big letters somewhere on the front page of the rpy2 website?
