dmultinomial

Hello All,
I''m trying to run a maximum likelihood analysis using dmultinomial (i''m
avoiding dmultinom as I''d like to run it with vectors for the ML stuff).
However, I''m having a hard time getting even the simplest example
running. Any help would be greatly appreciated.

Efficient multinom probs

...the
following:
y=sample(1:3,15,1)
prob=matrix(runif(45),15)
prob=prob/rowSums(prob)
diag(prob[,y])
However, my question is whether this is the most efficient way to do this.
In the call prob[,y] a whole matrix is computed which seems a bit of a
waste.
Is there maybe a vectorized version of dmultinom which does this?
Best, Ingmar

fisher.test - can I use non-integer expected values?

I seem to be able to use expected values that are decimal (e.g., 1.33) when
using chisq.test but not when using fisher.test. This happens when using an
array/matrix as input. Fisher.test returns: Error in sprintf(gettext(fmt,
domain = domain), ...) : invalid format ''%d''; use format %s for character
objects.
Thus, it appears fisher.test is looking for integers only.
I tried
