[R] R.matlab package help

[Henrik Bengtsson]

Hi,

the reason for your problem is that there is a single quotation mark
in the temporary pathname generated by Matlab which confuses Matlab
when trying to save the file.  Try replacing the existing
MatlabServer.m file (should be in the directory where Matlab is
running), with this file:

http://www.braju.com/R/patches/R.matlab/20100827/MatlabServer.m

Let me know if it works.  If so, I'll submit a new version of R.matlab
to CRAN with the fix.

/Henrik
