Re: [R] R.matlab package help
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 useful and only confuse me more. Can you please show me exactly what you do and what you get in both Matlab and R, otherwise there is no way I can help you solve this. I also do not know whether or not you installed that new version that I suggest. You are the first one having this problem and it has to do with you having an apostrophe in your Windows user name. /Henrik On Sat, Aug 28, 2010 at 2:22 PM, michael tufemich...@gmail.com wrote: Henrik, Yes I replaced the MatlabServer.m and restarted Matlab and R, it seems the problem is still there.

Re: [R] R.matlab package help
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:
Received cmd: 1
eval string: B
B =

Sent byte: 0
Received cmd: 1
eval string: variables = {'B'};
Sent byte: 0
Received cmd: 2
save tempname-V6 B

One final question, the variable B I got from Matlab is not just a numeric
value, it is:

The getVariable() function returns a named list where each element
contains the value of a particular Matlab object. You can request more
than one variable in each call. You need to use standard R list
operators to extract the element you'd like. For example:
data - getVariable(matlab, c(B, A));
B - data$B;
A - data$A;
Thus, instead of writing:
B - getVariable(matlab, B);
B - B$B;
it is less confusing if you write:
data - getVariable(matlab, B);
B - data$B;

Re: [R] R.matlab package help
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 values, e.g. eval(matlab, A); That will show you the value as in Matlab before being transfer to R. In that example, it is also suggested to do setVerbose(matlab, -2); That'll give you more details on what is done under the hood. To make sure I understand you correctly, you are trying to do this where Matlab is started on the same machine, correct? BTW, have you had any success running R.matlab before or is this your first try?

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

Re: [R] R.matlab package help
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 On Fri, Aug 27, 2010 at 12:27 PM, michael tufemich...@gmail.com wrote: Henrik, Here is the matlab response: MatlabServer Matlab v7.x or higher detected.

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. /H On Fri, Aug 27, 2010 at 3:56 PM, michael tufemich...@gmail.com wrote: Henrik, I updated the MatlabServer.m from the link you sent to me, but it still doen't work.

Re: [R] R.matlab package help
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:
Retrieving variables from the Matlab server: 'B'
Sending expression on the Matlab server to be evaluated...: 'variables =
{'B'};'
Received an 'OK' reply (0) from the Matlab server.
Evaluated expression on the Matlab server with return code 0.
Asks the Matlab server to send variables via the local file system...
Error in file(con, open = rb) : invalid 'description' argument
Thanks,
Michael

Also the lines before.
