# [R] Plotting an Underbrace in R

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

Thanks.

Michael
