[R] Add column to the output of summary(glht).

[John Sorkin]

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 HypothesesMultiple Comparisons of Means: Tukey ContrastsFit: 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    0.7173 - 1 == 0   0.6554     0.5000   1.311    0.5514 - 1 == 0   0.9357     0.4655   2.010    0.1813 - 2 == 0   0.1234     0.4174   0.296    0.9914 - 2 == 0   0.4037     0.3754   1.075    0.7004 - 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")))] ?
 
Thank you
John
