The mefa 1.1-2 is on CRAN now. This is a bugfix release, and includes a new generic for reporting, an updated vignette and some new functions (as.mefa, accumulate). The code is slightly adjusted according to forthcoming object classes (xclist, mflist) available in a patch file (these will be incorporated into the next major release).

mefa 1.0-4 on CRAN

Peter Solymos - 2008-02-13 13:03 - mefa - Multivariate data handling

I put latest version of 'mefa' package to CRAN. It includes S3 methods for object classes, and several improvements. Code of classes were entirely rewritten for consistency. I have tested it for 2 months using several real data sets (as part of my research): it worked well. Bug in 'report.mefa' will be fixed in the next release (it is already done at r-forge SVN repository).
