I'm using Rpy2 on windows 7 64 and having trouble loading a package:
in R:
using(mi)
in python:
from rpy2.robjects.packages import importr mi=importr('mi') --------------------------------------------------------------------------- RRuntimeError Traceback (most recent call last) <ipython-input-30-2d393a6df544> in <module>() ----> 1 mi=importr('mi') C:\Anaconda\lib\site-packages\rpy2\robjects\packages.pyc in importr(name, lib_loc, robject_translations, signature_translation, suppress_messages, on_conflict, data) 397 if _package_has_namespace(rname, 398 _system_file(package = rname)): --> 399 env = _get_namespace(rname) 400 version = _get_namespace_version(rname)[0] 401 exported_names = set(_get_namespace_exports(rname)) RRuntimeError: Error in loadNamespace(name) : there is no package called 'm
Any suggestions?
I had a similar problem:
rpy2.rinterface.RRuntimeError: Error in loadNamespace(name) : there is no package called speedglm
I noticed that the issue is that rpy2 does not know the location of all R libraries. In my case, typing (in R)
.libPaths()
gave me
[1] "/home/nbarjest/R/x86_64-redhat-linux-gnu-library/3.4" [2] "/usr/lib64/R/library" [3] "/usr/share/R/library"
While, typing (in Python 3)
import rpy2.rinterface rpy2.rinterface.set_initoptions((b'rpy2', b'--no-save', b'--no-restore', b'--quiet')) from rpy2.robjects.packages import importr base = importr('base') print(base._libPaths())
gave me only
[1] "/home/nbarjest/R/x86_64-redhat-linux-gnu-library/3.4"
I couldn't find a way to append the other two paths to base._libpath(). If you find a way to do it, please let me know. I used another workaround:
import rpy2 import rpy2.robjects as RObjects from rpy2.robjects.packages import importr utils = importr("utils") d = {'print.me': 'print_dot_me', 'print_me': 'print_uscore_me'} try: thatpackage = importr('speedglm', robject_translations = d, lib_loc = "/home/nbarjest/R/x86_64-redhat-linux-gnu-library/3.4") except: try: thatpackage = importr('speedglm', robject_translations = d, lib_loc = "/usr/lib64/R/library") except: thatpackage = importr('speedglm', robject_translations = d, lib_loc = "/usr/share/R/library")
This works. I hope other people who have the same problem find this useful.
