[R] Censored Poisson Data

Dear list,

I am wondering whether R allows to perform a Poisson regression on 
counting data which include censored observations, that is, observations of the form 
"2 events or more" or "less than 2 events" or even "1 or 2 events".

Can anyone give me a hint whether this is already possible and how to do it?

Data of the form (obstime is the observation time, "offset" in Poisson 
regression):

obs   obstime   cmin   cmax
1      1             2         Inf
2      2             0         1
3      1             1         2

and so on.

Best wishes,

Justine
