Dear List-Members, Is the application of multiple comparison procedures (using the multcomp package) to the output from a rank-based ANOVA straightforward, or do I need to take heed ? That is, is it as simple as: glht( aov(rank(NH4) ~ Site, data=mydat), linfct=mcp(Site="Tukey") ) Thanks in advance for your help. Regards, Mark Difford. -- View this message in context: http://www.nabble.com/Multiple-comparisons--rank-based-anova-tf4516025.html#a12881037 Sent from the R help mailing list archive at Nabble.com.
