I suggest sending a copy of this question to the authors of the package 
with a motivating example. I do note, however, that using the formula 
interface to sarprobit() permits for example:

sarprobit.fit <- sarprobit(y ~ X[,3] + offset(1*X[,2]), W, ndraw=1000,
   thinning=1, prior=NULL)

using the example on the function help page. See ?formula for the offset() 
term.

Hope this helps,

Roger
