No, zeroinfl() in pscl did not give me any errors when I ran the
model. So there may be a bug in zicounts. Only problem now is how
to interpret the zeroinfl model. Am I correct in my understanding
that zeroinfl runs both the poisson and binomial models without
interactions? I'm thinking

Hi Jim,
Two thoughts come to me, unencumbered by the thought process or
knowledge of zicounts:
1. Is Poisson really NOT appropriate? (do you have to use zicounts?)
2. Are you 110% certain that all variables are the same length? Would
NA's interfere?
Cheers,

your problem is in the statement:
if(mat.all[i,(j-int):(j-1)]<0){
you have multiple values in the comparison and the 'if' statement can only
use a single value. Do you want the statement to read:
if(all(mat.all[i,(j-int):(j-1)]<0)){
which will test for 'all' the comparisons to be true?

Hi Karen --
This sounds like a Bioconductor question, and should be sent to the
Bioconductor list.
http://www.bioconductor.org/docs/mailList.html
Likely the complaint is about RMySQL being too old, rather than R. The
idea of 'reinstalling folders' doesn't sound like a good strategy for

I don't know how to get that particular error message from lmer, but

So this is most likely a bug in package nlme. However, we need a

Robin,
This is a problem with coda's mcmc summary method. I suspect it is in
the spectrum0() call therein, but I don't know for sure.
For your immediate purposes you could extract the posterior density
sample as a matrix from the mcmc object and manually compute quantities
of interest.

The message says at some point in the calculation, R tries to get about

Is one of your variance components essentially estimating zero?
If you check the numbers, delete the smallest one, and then do "anova"
comparing the two fits, you might find that the one you deleted was not
statistically significant.

You should use nls, not nlsModel.
Also, if P is fixed then this is a linear regression model. Why use
nonlinear regression.
