Error in loadNamespace(name) : there is no package

问题:

Error in loadNamespace(name) : there is no package called 'Rcpp' ... Error in loadNamespace(name) : there is no package called 'RInside'

I get the above error when trying make on the examples of RInside.

RInside is in the user-library. So I set R_LIBS_USER to the directory in the Makefile.

R_LIBS_USER := "C:/users/Me/Documents/R/win-library/3.0"

but that does not work either.

Thanks for any advice.

EDIT:

It works fine if the packages are in "C:/R/R-3.0.2/library". R_LIBS_USER doesn't seem to work on Windows.

回答1:

I fear this is local to your end.

If Rcpp and RInside are in fact in your default library location (and on Windows I sometimes copy them) then the examples build, as does the rest of the package. Recall that all this works for CRAN and the win-builder.

I was also having the same problem and read Dirk's reply and just ran

 install.packages("Rcpp", dependencies = TRUE)
 install.packages("RInside", dependencies = TRUE)

and it is working fine now.

I know the question was asked long back. But I faced the same problem while using R from python (Anaconda). Also I didnt find an reasonable explanation for it. Finally this is what worked for me.

import rpy2.robjects as ro

ro.r('''.libPaths('C:/Users/<remaining path>/R/win-library/3.1')''')

RSVM = importr('e1071')
