[R] Label using equivalent of \mathbb{R}

[Simon Cullen]

Hi,

I'm trying to label the horizontal axis of a plot with a symbol that is  
the equivalent of \mathbb{R} in LaTeX. I've had a look through the help  
pages for plotmath and for Hershey and haven't found the symbol. Could  
someone give me a pointer, please?

Using R 1.9.1 on Win32.
