I'm using the vglm function of the VGAM package.

m <- vglm(log(variable+1) ~ ., tobit(Lower=0), data = dat)

I was able to run the code above without any issues previously, but I'm getting this error message.

EDIT:

Also tried running this vglm(log(demand+1) ~ ., tobit(Lower=0), data = BOD)

but I'm also getting the same error message
