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
