Re: [R] Error clmm(){ordinal}

Dear all, I want now to class my lines (Line) regarding to the model ceated with drop1() I installes packages lsmeans, multcompView, ordinal and RVAideMemoire which permit together to analyse data from clmm model. I ran the following script and had an error. I could find nothing about it on the

Re: [R] Error clmm(){ordinal}

Dear Rune, Thanks for your script using drop1()! It worked well! Now I know I have significant effects for my predictors. Best regards Aurore -- View this message in context: http://r.789695.n4.nabble.com/Error-clmm-ordinal-tp4691592p4691969.html Sent from the R help mailing list archive at

Re: [R] Error clmm(){ordinal}

Aurore, I don't know if car::Anova is able/should be able to produce anova tables for clmm objects; I usually use drop1() (and sometimes add1) to test terms in CLMMS: library(ordinal) fm1 - clmm(rating ~ temp + contact + (1|judge), data=wine) drop1(fm1, test=Chi) Single term deletions Model:
