[R] analysis of life tables

[Christoph Scherber]

Dear all,

How can I analyze a life table (e.g. for a cohort of insects) in R?

I have 20 insects in 200 cages with two different treatments, whose 
survival is followed over time, such that, e.g., in one treatment, the 
number of animals surviving is c(20,18,16,12,10,8,4,0), while in the 
other treatment the survival is c(20,20,18,18,16,15,15,14) at 8 
subsequent time intervals.

I would very much appreciate any suggestions on how to analyze such a 
dataset.

Best regards
Christoph.
