Dear Uwe,
thanks for your help. Actually, I first thought about writing your solution in
the email in order to make clear that it is not the solution I'm looking for
:-) My goal is to work with the vector "vars" of expressions. The example is
only a minimal example and for that your solution is perfectly fine, but my
original problem is more complicated and there it makes sense to work with a
vector of expressions. Do you know a solution to that? I tried many things...
the obvious plot(0, 0, main=substitute(bold("Foo" ~~ VAR), list(VAR=vars[2]) ))
did not work...
Cheers,
Marius
