R help - Jan 2013 - Lambert W question

Dear All,
 
I am using the following model equation:
 
k*(lambertW_base(b=0,((a)/k)*exp(((a)-z*(t-t0))/k)))
 
I would like to run this through OpenBUGS, but it does not recognize the lambert
function. Would you have any thoughts on how to re-vrite this equation
matemathically so that it could be run on OpenBUGS?
 
apreciate the help,
 
Sincerely,
 
Andrs

I don't know anything about OpenBUGS, but implementations of the Lambert W
function exist, or you could roll your own.
