Hello,
May i know whether it is possible to generate data twice from Weibull
distribution and use one as the start time and the
other as the end time, below is my code.
Any suggestion on how to estimate the parameters of Weibull distribution with
interval data will be highly appreciated.
Thank
Bert
I have read Deepayan's book and done all the examples but there is no

I just cannot get the fully meaning of what has been written
regarding passing arguments to panel functions.

I did get subset to work on a character vector last night, the only difference
being I used two equals signs:

I am unsure why this is, but it worked. I believe this

R works on the idea that factor level ordering is a property of the
data rather than a property of the graph. So if you have the factor
levels ordered properly in the data, then the graph will take care of
itself. To order the levels see functions like: factor, relevel, and
reorder.
