Hello,
This is because you have non-integer values in vector x?
This one works.
##Poisson distribution
f2p <- fitdist(floor(x), "pois")
plot(f2p)
summary(f2p)
Not so well
##negative binomial distribution
f2n <- fitdist(floor(x), "nbinom")
f2n <- fitdist(ceiling(x), "nbinom")
f2n <- fitdist(round(x), "nbinom")
plot(f2n)
summary(f2n)
Hope this helps,
Rui Barradas

Dear R-Experts,
Here is a toy example, reproducible example, I get error messages. I have tried to fix it
by myself using "google is my friend", but I did not get it. If somebody can
help me to fix these errors, would be highly appreciated.

x=c(3,3.5,4.5,5,5.5,5.5,4.5,3.5,5,6,3,4,5,4.5,4,5.5,3.5,3,3)
##Poisson distribution
f2p=fitdist(x, "pois")
plot(f2p)
summary(f2p)
##negative binomial distribution
f2n=fitdist(x,"nbinom")
plot(f2n)
summary(f2n)
