[R] Plotting an Underbrace in R

[Michael McAssey]

Baptiste,

Thank you.  The examples in the documentation for tikz helped me solve
this problem, and give me a good tool for future plots.  I only need
to figure out how to incorporate LaTeX packages like amssymb so that I
can use \mathbb{} to put the real numbers symbol in my plot.

Regards,

Michael
