[R] ERROR: gamm function (mgcv package). attempt to set an attribute on NULL

[Simon Wood]

Thanks. This is a bug, the source code made an implicit assumption that there 
would always be at least one smooth, when creating the gam object after 
fitting. Fixed for the next release (1.7-5). For now, you could use glmmPQL 
from the MASS library to get an equivalent fit when there are no smooth 
terms.
