[R] Queueing models

[Coburn Watson]

Hello R-Help,

Is anyone aware of an R package which which handles queueing models (M/M/1, 
etc)? Basically I was looking for a package which applies Little's law and 
other methods to analysis of continuous state Markov processes (to calculate 
predicted time spent in queue based on workload).  I might be off base on 
this and be looking for something which shouldn't exist within a package like 
R (but just a simple spreadsheet program).  There are such plug-ins for Excel 
(QTP, etc) but I have started using R more significantly at work and was 
looking to see if it had additions in the queueiing arena as well.

Thanks,

Coburn (please remove _nospam from email to reply directly).
