The mefa 3.1-0 has been submitted to CRAN. This major release includes many helper functions and coercion methods for data manipulation.
The mefa package (version bumped to 3.0) is published in the Journal of Statistical Software (http://www.jstatsoft.org/v29/i08/).
The mefa 2.0 is available on CRAN. I have completely revised the code to speed up data processing. In addition, many new methods are available for manipulating the community data matrix and related data tables for samples and taxa as well. A new vignette will be available soon.
I have corrected the proof of the software abstract that will appear in the journal Community Ecology, introducing basic features of the package, with diagrams showing the data model and the workflow.
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).
I have just submitted latest stable version (1.1-0) of the mefa package to CRAN. Major improvements since 1.0-4 are: vignette is made available and can be used as reference for the demo, bugfixes for add.attrib and report.mefa, print and plot methods are improved, new functions included (qdef, mapmf, accumulate, ivgen, xytrend).
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).
