Folks,
Since Aaron has revive the group with his grouped data question, I thought I'd pass along some code I have posted under my R Applications page. I'll get a manuscript associated with this code up soonish. there are several pieces of code in the zip and the Weibull6.R file. There is a set of rdpq functions to do most of the variants of Weibull - 2P, 3P, reverse, left and right truncation. There is an MLE parameter estimation function as well as a parameter recovery function. There is also an interactive parameter finder.
Any comments are greatly appreciated.
