Dear Masters,
I have a question to submit
consider the following script
m<-4.95
obs<-rpois(36,m) # i generate 36 realization from a poisson(m)

theorical poisson density function
errors are returned saing the x vector doesn't contain integers....

M1lme <- lme(logA ~ C.f * D.f, random = ~1 | F.f, data = rfreq)
> summary(M1lme)
> anova(M1lme)

(Intercept) 1 87 75.50639 <.0001

D.f 4 87 22.74062 <.0001
C.f:D.f 20 87 3.77657 <.0001
