Dear all,
I still need help (I am a newbie to R).
I looked on the plotmath help and could not find how Unicode can be used.
And I am in a Windows platform which I don't know if it is relevant. Can
anyone help? Here is a simple example
plot(1:10,1:10)
can anyone provide the code to insert a "nabla" anywhere on it?
thanks

I have not tested it, but according to
http://www.gnu.org/software/plotutils/manual/html_chapter/plotutils_10.html
nabla is Unicode [0321]
Check documentation on plothmath how to use it.
Note: the documents cited in plotmath are huge, and it would be nice to have
something like the gnu-reference I google for a short list.
