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 really that big a calculation?

to start:

mle2(minuslogl = Lily_sum$seedlings ~ dnbinom(mu = a, size = k),

start = list(a = 10, k = 1))
then:
i2<-interaction(Lily_sum$flowers, Lily_sum$gopher)

i3<-interaction(Lily_sum$flowers, Lily_sum$rockiness)

mle2(Lily_sum$seedlings ~ dnbinom(mu = a, size = k), start=list(a=10,k=1)
,parameters=list(a~i3+i2+Lily_sum$flowers))

(the last run leads to a stalled calculation)

regards,

R
