Re: [R] Minitab Parametric Distribution Analysis in R
After a bit of coaching I found what I was looking for: the fitdistr() function in the MASS package. It appears to be a bit easier to use than mle() for my application. Thanks all.

[R] Minitab Parametric Distribution Analysis in R
Minitab can perform a "Parametric Distribution Analysis - Arbitrary Censoring" with one of eight distributions (e.g., weibull), giving the maximum likelihood estimates of the parameters in the distribution for a given dataset. Does R have a package that provides equivalent functionality? Thanks for any advice you can offer.
