[R] Quantitative Microbial Risk Assesment??

[Steven R. Corsi]

Hi, I am searching for a script or set of scripts written in R that 
perform Quantitative Microbial Risk Assessment (QMRA) computations for 
risk of infection from pathogens in recreational waters. My initial 
searches have come up empty. If there are other places I should look for 
this or email lists I should be using, please feel free to forward those 
suggestions to me also.
Thanks
Steve
