Hi Gbemisola, You can find functions for diallel analysis (Griffing and Hayman) and LxT analysis in several R packages: agricolae (on CRAN), DiallelAnalysisR (on CRAN), plantbreeding (on R-forge), and AGD-R (on the CIMMYT website; a front-end built on R).
If these are not enough (!) you could try other stand-alone software, such as: PBTOOLS, GENES, QGAStation, TNAUSTAT, ICRISAT Genstat scripts, GSCA (not free), or Dial98. HTH, Cheers David Luckett djluck...@gmail.com 0408 750 703 ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
