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.

install.packages("fitdistrplus")
library(fitdistrplus)
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)

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 ?s 09:46 de 29/05/19, varin sacha via R-help escreveu:> Dear R-Experts, > > Here is a toy example, reproducible example, I get error messages.

Dear Rui, Many thanks, it perfectly works. Yes it was because of non-integer in vector x. best, Le mercredi 29 mai 2019 ? 11:55:06 UTC+2, Rui Barradas <ruipbarradas at sapo.pt> a ?crit : Hello, This is because you have non-integer values in vector x?
