Hi! I'm a bit lost while performing multiple comparisons on a lme model of that type:
lmeglu=lme(glucose~Ath*tim,random=~1|Vol,na.action=na.omit,data=data) multc = glht(lmeglu, linfct = mcp(Ath = "Tukey", tim = "Tukey")) This works fine for identifying the effect of each factor. However, when I look for their interactions, l only obtain error messages. For example this leads to a syntax error... multc2 <- glht(lmeglu, linfct = mcp(Ath:tim = "Tukey", tim = "Tukey")) I try to identify/locate differences in glucose concentration (glucose in the model) between groups (Ath) at each time point (tim). Thanks a lot for your help Regards Virgile -- View this message in context: http://www.nabble.com/Multiple-comparison-on-lme-model-with-2-fixed-factors-tp25002051p25002051.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
