driving R from MATLAB

I am not using it with Matlab, but quite extensively with C#. The somewhat
strange error message you noted "Object is static" has always been an error in
the script.     

When I am sure that the script works Ok when run separately, it frequently has
to do with the current directory being different when run with RDCOM and from
GUI. Therefore I explicitly set the working directory at the top of all scripts,
or get is from an environment string.

The most helpful tool is a character device in my application that outputs the R
string directly, so I immediately see what the cryptic "Object is static" means.

This is about 'a' DCOM server.  You haven't told us which (there are at 
least two possibilities), but if it is the one by Thomas Baier it has its 
own mailing list.  This is not an R issue (and I suspect not a MATLAB one 
either), so please try to use an accurate subject line.

I am trying to use R functions from my MATLAB code using a DCOM server.
I am working under Windows XP.

While I mange to run basic functions and run them using scripts, when I
try a more complicated set of functions I fail.

I tried to get around this by using a script, but it doesn't work. I do
not actually want to transfer the Surv output back to MATLAB, but rather
allow R to plot some graphs, actually Schoenfeld residuals, which works
fine within R, but I can't work out if R can be instructed to perform
this analysis by MATLAB

Does anyone know how?

Thanks!
