Install rpy2 with custom R installation -

-

i have custom installation of r in

~/r-3.2.2/bin/

when run

sudo pip install rpy2

i 

    warning: tried guess r's home no command (r) in path. traceback (most recent call last):   file "<string>", line 17, in <module>   file "/tmp/pip-build-itkmkr/rpy2/setup.py", line 330, in <module>     ri_ext = getrinterface_ext()   file "/tmp/pip-build-itkmkr/rpy2/setup.py", line 231, in getrinterface_ext     r_home = _get_r_home()   file "/tmp/pip-build-itkmkr/rpy2/setup.py", line 63, in _get_r_home     r_home = r_home.split(os.linesep) unboundlocalerror: local variable 'r_home' referenced before assignment

i have found no answer problem, though appears in several posts. here tried

  • add r executable path

    export path=$path:/home/r-3.2.2/bin/ did not work

  • export r_home same value: did not work

  • echo export path=$path:/home/r-3.2.2/bin/ >> ~/.bashrc source ~/.bashrc

did not work.

on other hand "problem" seems solved here https://bitbucket.org/rpy2/rpy2/issues/283/rpy2-installation-error-when-r-output

how install rpy2 correctly?

the error because of issue in rpy2 (just fixed). otherwise, might because r either not in path think is, or may not have permission run it.

try:

# assert r executable think ~/r-3.2.2/bin/r --version # set path export path=${path}:~/r-3.2.2/bin/ # unset r_home if needed unset r_home # install rpy2 pip install rpy2
