[R] cannot plot too much (using Mac interface)

Thanks.  And sorry for abusing the word crash.  I understand the
difference.  However, now that you mention it, there is a case where I
think R is crashing.  I'm not sure if it's R or if it's the Mac OS
interface, but if I try to plot something complicated (or a series of
complicated things) while rendering them at the same time, R will
freeze and eventually fail.  I've been trying to avoid doing that,
creating an object separately and then ploting that object, for
example, or plotting one thing at a time instead of using a for loop.
But sometimes I forget and end up loosing my work because of it.  Next
time it happens, I will copy down what the command was that does it,
though I'm not sure how useful that will be because it usually depends
upon some of my own functions which are, in turn, built on the
tseriesChaos package.  I figure it's R running out of memory or
something.  Any ideas?
