Karl, Yes, I am familiar with that Web site. I was disappointed that the forum lacked any activity. No response to my posts.
They have a forum for CoDa related questions. There seems to be a new R-package for CoDa: zCompositions.
zCompositions is installed here. It focuses on principled methods to deal with zeros and left-censoring in compositional data sets. Also installed are robCompositions for various imputation methods for missing data and the new (version 1.4.0) compositions. The tools are present and the documents read. Now I need to learn how to select the appropriate options for the data sets to be analyzed and the questions to be answered. Many thanks, Rich _______________________________________________ R-sig-ecology mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
