FAQ for the RMatlab Package

When I try to run R inside Matlab, I get the following error:

>> initializeR({'RMatlab' '--silent' '--vanilla'})
initializeR({'RMatlab' '--silent' '--vanilla'})
??? Undefined command/function 'initializeR'.

The problem is that you have to tell Matlab where to find the MEX files that makeup the Matlab-to-R interface. You do this (on Unix, at least) by setting the environment variable MATLABPATH to contain the directory containing the MEX files. These are installed in the R package directories. The simplest way to

When I try to run Matlab inside R, I get the following error:

> library(RMatlab)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library "/home/sharesly/Rpackages/RMatlab/libs/RMatlab.so":

The problem is that you have to tell R where to find the relevant Matlab shared libraries. You do this (on Unix, at least) by setting the environment variable LD_LIBRARY_PATH to contain the directory containing the necessary *.so files. For instance,

    setenv LD_LIBRARY_PATH /usr/local/matlab-7.0.1/bin/glnx86:{LD_LIBRARY_PATH}
