Error when choosing "binomial" in the bw.ggwr function in the 'GWmodel" R-package

Hi,

I want to run the Generalized GWR model using the binomial family but I'm getting the following error when getting the bandwidth with ```bw.ggwr()```:
```
Error in if (abs((old.llik - llik)/llik) < tol) break : 
  missing value where TRUE/FALSE needed
```
This seems like an internal error from the function. How can I fix this?
