Hi dears, I do
> CHOL<-lme(chol~rt*cd4+sex+age+rf+nadir+pharmac+factor(hcv)+factor(hbs)+ haartd+hivdur+factor(arv), random= ~rt|id, na.action=na.omit) ...runs sweet,..then ....try a multicomparisons approach for the categorical rf > summary(glht(CHOL, linfct=mcp(rf="Tukey"))) * Error in model.frame.default(object, data, xlev = xlev) : l'oggetto non è una matrice * <-- Object isn't a matrix!!* Errore in factor_contrasts(model) : no model.matrix method for model found! Errore in summary(glht(CHOL, linfct = mcp(rf = "Tukey"))) : error in evaluating the argument 'object' in selecting a method for function 'summary'* data are ok...I have followed the examples on ?glht ..,there is still something I'm missing here? Thanks in advance if you wish to give a tiny answer. -- *Little u can do against ignorance,....it will always disarm u: is the 2nd principle of thermodinamics made manifest, ...entropy in expansion.**....But setting order is the real quest 4 truth, ......and the mission of a (temporally) wise dude. * [[alternative HTML version deleted]]
