 Who told you about gw.adapt?

 It seems to now be not exported from the spgwr package, but the help
page is still there (Roger: is that a bug? Either you've missed it out
of the exports or you've left in the .Rd file!).

 If you want to use it you can use the triple-colon notation to get an
unexported function from a package:

res = spgwr:::gw.adapt(cbind(columbus$x,columbus$y),cbind(columbus$x,columbus$y),quant=0.5)

 Roger may have removed it for a good reason, and possibly put the
functionality into another function. But the quick fix would be the
triple-colon trick.

 It's also useful if you give package versions with your questions -
here's mine:

> packageDescription("spgwr")$Version
[1] "0.6-14"
