R help - Sep 2004 - fitting weibull distribution

Dear all,

I get the following error message. And I cannot quite work out what is
wrong. I think the optim gets infinite values. Certainly my data do not
have any infinite values. How can I solve this?

fitdistr(A1, "weibull")
Error in optim(start, mylogfn, x = x, hessian = TRUE, ...) :
        non-finite value supplied by optim


I am using R version 1.9.1 on RedHat Linux, Kernel 2.6.8.

Hi.

I think there may be one or more zeros in your data set, causing the
problem:

x <- rgamma(100)
fitdistr(x, "weibull")
fitdistr(c(x,0), "weibull")

Maybe you should omit the zeros.

Hi,

How I can see the members of clusters generate by AGNES or DIANA (package
"clusters")?

Thanks,
