Dear members,

I am using gwr.mixed and gwr.basic functions  in package "GWmodel". In the
function specifications it has mentioned that argument: fixed.var, which is
 independent variables appeared in the formula to be treated as global
I am wondering how should I specify (maybe fixed.var = x3+x5+x7).
since I am getting

Error in match(fixed.vars, colnames(x)) :
  object 'x3' not found

Besides:

In gwr.basic results I am  getting :
 ******************F test results of GWR calibration********************
   ---F1 test (Leung et al. 2000)
Error in `rownames<-`(`*tmp*`, value = "   ") :
  attempt to set 'rownames' on an object with no dimensions

I appreciate if help me with these two errors.


I am running R  version 3.0.2 (2013-09-25) -Platform:
x86_64-w64-mingw32/x64 (64-bit)
