OK, I think it is just B[1].
Thanks!

Henrik,
OK, finally I got the problem: I have an apostrophe in my
windowns 7 user name. That mess up the file name. So I logged in using a
guest account and it works:

Michael,
could you please give me *verbatim* details on what messages you are
seeing. In your previous reply you did *not* report seeing
"save(tmpname, '-V6', 'B');" and now you say you get it. Please do
not abbreviate what you are getting (e.g. "save(temp,-v6,B)"), because
that will not be usef
Henrik,
Yes I replaced the MatlabServer.m and restarted Matlab and R, it seems the
problem is still there. I see save(temp,-v6,B) there too. I use
MatlabServer.m mannually in Matlab, actually I couldn't use it in R, Matlab
will pop up a command window and never respond.
Thanks,
Michael

I bet the problem is with the single quote (') in the path.

Henrik,
When I set remote=FALSE, I got this error:
??? Error: A MATLAB string constant is not terminated properly.
Error in ==> MatlabServer at 197
eval(expr);
In R:

Hi,
let's stick with the remote=FALSE case first. What output does Matlab
produce now? That is really key information in order to solve this.
Also, make sure that you really restart the MatlabServer.

Henrik,
I updated the MatlabServer.m from the link you sent to me, but it
still doen't work. I have the same problems as before, when remote=FALSE,
getVariable doesn't work; when remote=TRUE, setVariable says:

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:

could you send me what Matlab is outputting. When I send the following from R:

and Matlab should print something like:

Hi,
what is the version of Matlab you are running?
Could you show a minimum verbatim example - starting with a fresh R
session and library("R.matlab") - that gives you the error?
Have you tried the example of help(Matlab)? Then, for troubleshooting
it could be useful to ask Matlab to display va
Henrik,
Thanks for your reply. I am using Matlab version
7.9.0(R2009b). This is my first try using R.matlab. I started matlab
in the same machine, and I run the MatlabServer.m in matlab, here is
my code in R:
library(R.matlab)
library(MASS)
matlab <- Matlab()

I updated R and still have the problem.
When I set

and I changed remote = false, same problem pops up:

David,
Thanks for your reply, I compile it under the old version of
R, I'll update R and run it again.
