Please try to create a complete example with built-in data first. Also 
look carefully at your input data - is there anything specific about your 
data that the built-in data set doesn't match (eg. a factor covariate?). 
Finally, pasting the output of traceback() run immediately after 
gwr.mixed() fails may show where in the function the problem arises.
