Offset for spautolm function in Spatialreg package

Dear members of the R-sig-Geo,
Is there a way to set an 'offset' when running a Poisson regression using
the spautolm function offered in the Spatialreg package?

I have count data of disease at administrative levels and I am trying to
use CAR model to account for the spatial dependence between the admin
levels. I would appreciate suggestions of setting the offset (the log of a
total number of animals in each admin level) or ways to work around this
using spautolm function.

Thank you very much.

Further details below:

# Unit of analysis is ?Districts? i.e. administrative divisions

# Count_disease = number of animals with the disease

# Var 1 and 2 are selected independent variables

# We have the count of animals per each district and I am trying to set
this as the ?offset?



# The same model was run as a zero inflated Poisson regression using the
following

offset = log(Ani_pop)

ZIP.D <- zeroinfl(formula_Red, data = Data, dist = "poisson", EM = TRUE,
link = "logit", offset = offset)



#Formula

formula <-  Count_disease ~  Variable 1 + Variable2

# CAR fit

CAR.D <- spautolm(formula_Red, data= Thai.D.shp2, listw=ThaiD.listw,
family="CAR",zero.policy = TRUE, method="eigen")



How to set the offset?

Or suggestions to work around this?
