The short answer is that you're trying to make a categorical interaction
out of
continuous variables, so that the resulting factors i2 and i3 have 1050 and
7200
levels respectively. (Note to people trying to reproduce this example:
you'll
need library(emdbook); library(bbmle); data(Lily_sum)
Hello,
After putting together interaction code that worked for a single pair of
interactions, when I try to evaluate two pairs of interactions(
flowers*gopher, flowers*rockiness) my computer runs out of memory, and the
larger desktop I use just doesn't go anywhere after about 20 minutes.
Is it
Use Rprof on a small sample and determine where the time is being
spent. Do some periodic gc() or memory.size() to see how fast you are
using up memory. Do an object.size on all your objects to see see how
be they are. This would help in the determination of the problem.
