[R] Plot dagger symbol in R

[Rau, Roland]

Dear all,

thank you very much.
Yes, indeed, I should have included the sessionInfo().
Both examples (unicode and standard encoding) work fine; however, I
prefer the suggestion by Prof. Ripley since it allows me to do things
like:

plot(1, main=expression(e^"\206"))

This fails, however, with:

plot(1, main=expression(e^"\u2020"))		

Thank you once again,
Roland
