Hi,
as already mentioned, do not save MAT files in ASCII format but save
to binary formats, i.e. do *not* use -ascii. Moreover, from
?readMat, you find that:
From Matlab v7, _compressed_ MAT version 5 files are used by
default [3]. These are not supported. Use 'save -V6' in Matlab to
Have you tried 'getVariable' from Matlab? I also recently failed
to get 'readMat' to work for me -- probably because I hadn't saved the
files using the options Henrik suggested below.
Fortunately, I was able to get something like the following to work:

Dear R-Experts,
here again a question concerning matlab. With the command matrixM=[1 2
3;4 5 6] a matrix under Matlab was constructed. It was than stored with
the command save('matrixM.txt','matrixM').
Now I tried to import the data in R with the help of the command
I've used Henrik Bengtsson's R.matlab package several times to successfully
read in matlab data files. It's normally as easy as:
library(R.matlab)

I have imported this package, too. And tried your commands with the new

With readMat, don't use the -ascii option (which you didn't have in your
first posting). I've never tried reading matlab's ascii format. In any case,
readMat reads matlab's binary format.

I did the saving again without 'ascii' option but the import also did not work.
I get the
Have you considered exporting from Matlab using the '-ascii'
option, then reading it with 'read.table', after perhaps checking the
first few rows using, e.g., 'readLines', and confirming that all records
have the same length using 'count.fields'?
Hope this helps.
