Hi Metastate,

Yes, I found there is a problem in the function gwr.mixed, as the Line 119 code should be :
SpatialPolygonsDataFrame(Sr=polygons, data=mgwr.df, match.ID=F)
but the parameter "match.ID=F" is missed.
I've revised it in the attached code. Currently you can re-source this function after loading the package. It will be fine to run you command. I will update the code in the next submission of package. Cheers.

Best regards,

I applied the gwr.basic and gwr.mixed on the same SPDF file using the codes
below. I got an error message on gwr.mixed:
Error in SpatialPolygonsDataFrame(Sr = polygons, data = mgwr.df) :
row.names of data and Polygons IDs do not match
I had no problem with gwr.basic.
The code I used was:
gwr.res2 <- gwr.basic(Yield_Detrend~Tsfc_4_10+PCP_IN_7_8+PCP_IN_4_6,
data = Yield.spdf.sub,kernel = "bisquare", adaptive = TRUE, bw=50,
F123.test = TRUE)
mgwr.res2 <-gwr.mixed(Yield_Detrend~Tsfc_4_10+Pcp_30D_LT_2IN_4+PCP_IN_7_8
                  +Elevation, fixed.vars=c("Pcp_30D_LT_2IN_4",
"Elevation"),data = Yield.spdf.sub,kernel = "bisquare", adaptive =
TRUE, bw=50, diagnostic=T)
Also, Is it any easy way I can provide the spdf file if you need it to
Thank you very much for your help.
