Hello,
I have a C function that I call from R using .Call. I recently discovered a
bug in my code, and I am not sure if it is a problem with what I am doing in C
or if it has something to do with my use of .Call.
I have narrowed my problem down to these two C statements:

Hi Jake,
are you looking for argument panel.first of plot.default?
?plot.default
panel.first: an expression to be evaluated after the plot axes are set
up but before any plotting takes place. This can be useful
for drawing background grids or scatterplot smooths.

Thanks Matthias and Gabor. You're both right. Matthias, I think that *was*
what I read although now I realize that Gabor's suggestion is more along the
lines of what I want to do. Though I have found one situation where this
wouldn't really work properly:

plot(rnorm(10))
10 matches
