Plotting an Underbrace in R

I need to include some mathematical expressions in a plot I am creating in
R, one of which requires an underbrace, which in LaTeX would be written like

\underbrace{T \cdots T}_{n times}

There does not appear to be a provision for this in plotmath, and I cannot
find anything on the topic in the R-help archive or in a Google search.  I
would appreciate some help with this.

library(pgfSweave)
plot(1:10, 1:10, "$Y=\\beta_0 + \\beta_1 x + \\epsilon$")

Ben,

This example of pgfSweave looks like it would address my problem.? I
installed this package, but I cannot determine how to use it to make R
convert LaTeX commands into mathematical symbols on an R plot.? The
documentation does not seem to address this.? I tried to mimic the
example from Yihui Xie that you provided but R only puts the LaTeX
code on my plot without converting it.? That is, if in the R GUI I
have:

library(pgfSweave)
plot(1:10, 1:10, "$Y=\\beta_0 + \\beta_1 x + \\epsilon$")

then in the plot the y-axis label is $Y=\beta_0 + \beta_1 x +
\epsilon$ rather than what I want. ?I can't find any useful help on
Google. ?Any further suggestions?

Thanks.

Michael

Hi,

Through pgfSweave you can use the tikz device, which is the one that
can interpret Latex code (package tikzDevice). I would start with a
minimal self-contained plot with this function. see ?tikz for
examples.

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
