I am trying to make the leap from an R users to an R aficionado . . . I am trying to understand how add a column to the output of summary (and to understand how summary() works). I have run a glmer fit0 <- glmer(Fall ~ Group+(1|PID),family=poisson(link="log"),data=data[data[,"Group"]!=0,]) and I want to perform adjusted multiple comparisons: SumTukey <- summary(glht(fit0, linfct= mcp(Group="Tukey"))) which gives beautiful output: > SumTukey
Simultaneous Tests for General Linear Hypotheses Multiple Comparisons of Means: Tukey Contrasts Fit: glmer(formula = Fall ~ Group + (1 | PID), data = data[data[, "Group"] != 0, ], family = poisson(link = "log")) Linear Hypotheses: Estimate Std. Error z value Pr(>|z|) 2 - 1 == 0 0.5320 0.5075 1.048 0.717 3 - 1 == 0 0.6554 0.5000 1.311 0.551 4 - 1 == 0 0.9357 0.4655 2.010 0.181 3 - 2 == 0 0.1234 0.4174 0.296 0.991 4 - 2 == 0 0.4037 0.3754 1.075 0.700 4 - 3 == 0 0.2803 0.3651 0.768 0.867 (Adjusted p values reported -- single-step method) I want to add a column to the output (unadjusted p-values), but I don't see how this might be done. The output is not a dataframe, nor is it a matix. > class(SumTukey) [1] "summary.glht" "glht" It is some class of objects that I don't understand and know nothing about. How can I add a column to the output of SumTukey [a.k.a. summary(glht(fit0, linfct= mcp(Group="Tukey")))] ?
