Yes, these are unimplemented.

Usually censoring is important in Survival Analysis, so you might check out any 
on that. This reference mentions estimating the hazard function via wavelets:


But when you say you want to 'separate based on smoothness within group', it 
like you are dealing with a classification problem. If so, there are many 
that might work. You could start here:

I don't know exactly what's wrong, but I would start by making
sure you have only one cygwin1.dll, and make sure it has all the 
necessary packages in it.
