[S] MLE's with censored data

I sent this note out a week ago, but have not gotten any response. Can
anyone answer the question below?

I am having a problem trying to get MLE's for a single population of life
data with some censored observations. It seems the gui portion of S+ 4.5
requires two populations to do any caluclations at all. After it has
finished, it is not clear where the parameter estimates are located in the
report screen. If I try to enter only one population, I get an error that
my design matrix is collinear. Does anyone know how get the parameter
estimates for a given distribution?

Thanks,

Charlie Whitman
