I can't believe I'm having such a hard time with this and I haven't
been
able to find out how to solve this...
lab <- expression( paste( hat(v),
as.character(round(y.hat,2)), ",",
hat(sigma)^2, as.character(sigma.hat)) )
text( x=pt$x+2, y=pt$y,labels=lab )
## the text should be \hat{y} = <value of y.hat>, \hat{\sigma}^2 ==
<value
of sigma.hat>
and R keeps displaying the actual text of the non-expressions...
I must be a chowderhead, but I need a little guidance, please...
Thanks,
Jeff.

Please visit the R site http://www.r-project.org/ and search the mailing
list for "paste expression" We discussed the topic recently. The
"trick"
is that you don't paste expressions, you make an expression containing
paste.
