<SNIP>

The syntax has to be do.call(function,list.of.args.to.function).

In this case:

     do.call(rbind,c(m,list(makeUniqueIDs=TRUE)))

BTW --- *don't* use the abbreviation "T" for "TRUE".  The object T is 
over-writeable (whereas TRUE is not!) and this can lead on occasion to 
mysterious errors accompanied by incomprehensible error messages.
