Dear all,
I have a vector of expressions and would like to "paste" some string to it
before using it in a plot:
vars<- vector("expression", 2)
vars[1]<- expression(alpha)
vars[2]<- expression(beta)
plot(0, 0, main=substitute(bold("Foo" ~~ VAR), list(VAR=vars[2]) ))
Although I tried hard, I just can't figure out how to solve this. The title should be
"Foo<theta>", where<theta> is the greek letter. I tried some constructions
with bquote but that wasn't successful... I also looked in the mailing list but couldn't find
anything helpful [I am sure I overlooked something].
plot(0, 0, main=expression("Foo" ~~ theta))

Cheers,
