Re: [R] R and reading matlab compressed files

Re: [R] R and reading matlab compressed files
According to the Octave manual (page 146 of Edition 3 for Octave version 2.9.16) Octave can read Matlab version 7 files. It can also output with similar options to Matlab. As there are no issues or licencing problems when running Octave and R on the one machine. Note that there is a new native Windows version of Octave now available that does not require cygwin.

By also zipping the file it will be comparable in size to the binary '.mat' format.

I know that R.matlab doesn't read them (it even says in the file MatlabServer.m Matlab v7 saves compressed files, which is not recognized by R.matlab's readMat() (lines 47-8)). See help(readMat), which says From Matlab v7, _compressed_ MAT version 5 files are used by default [3]. These are not supported. Use 'save -V6' in Matlab to write a MAT file compatible with Matlab v6, that is, to write a non-compressed MAT version 5 file. Note: Do not mix up version numbers for the Matlab software and the Matlab file formats. This should do if you have access to Matlab and you're in charge of the MAT files.
