Error with missing values in the response variable

[fred021]

I am fitting a Poisson model using CARbayesST, and as the vignette says, the three functions ST.CARlinear, ST.CARanova, and ST.CARar allow for NA's in the response variable. However, when I have missing values in the response, I get this error:

Error in if (any(y < 0)) stop("negative values not allowed for the 'quasiPoisson' family") :
missing value where TRUE/FALSE needed

Can you please tell me where I am making a mistake?

The issue is solved by running the following code before running the models:
options(na.action = "na.omit")
