In the example, an 's' is missing in line 3:

Elsewhere (at least in lme4), refit(sim(model)) does the
same thing [and so one would need something like
apply(sim(model,1000),2,refit)].
sim() is quite interesting, as is Zelig, but I'm not
sure I am ready to leap to it yet -- this was basically
a suggestion that simulate.glm could be includ
There is functionality similar to this included in the Zelig package
with it's "sim" method. The "sim" method goes a step further and
replicates the fitted model's analysis on the generated datasets as
well. I would suggest taking a look -- Zelig supports most (if not
all) glm models and a wide ran
I have found the "simulate" method (incorporated
in some packages) very handy. As far as I can tell the
only class for which simulate is actually implemented
in base R is lm ... this is actually a little dangerous
for a naive user who might be tempted to try
simulate(X) where X is a glm fit inst

The attached patch provides a modification to the recent fix/improvement
to do_grep already included in the most recent development version.
The original fix added new functionality to the grep function by adding
a new parameter, 'invert'. In the source code for the underlying

Hi John,
sorry for not posting more info. Strangely I get warnings about
setClassUnion with numeric in a very special case: if I define it in a
clean R session then there are no warnings, however if I load a number
of my packages where there are other classes derived from numeric and
exported then
