Hi Bill,
You were right, thanks!
Now I have:
int size = 5000;
double *matrix = (double *) R_alloc(size^2, sizeof(double));
Which works for larger sizes! But now I have discovered a new problem with it.
When I go to set the value of the elements it *sometimes* crashes:
for (i = 0; i < (size

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:
par(mfrow=c(2,2))
plot(rnorm(10))

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.
hth,
Mat
See:
?frame
e.g.
setHook("plot.new", function(...) cat("Starting plot\n"))
