Hi,
This is the bug in segment function,at the moment, infoWindow
works only for 3 variables. I'm sending to you alternative solution.
I'll fix it in new version of package. There will be fixed version of
segmentGoogleMaps, and added pie function which can be used for
spplot and plotKML.
library('plotGoogleMaps')
data(meuse)
coordinates(meuse)<-~x+y
proj4string(meuse) <- CRS('+init=epsg:28992')
source('pie.R')
a=pie(meuse,zcol=c('zinc','lead','copper'))
a$col=rep(c('zinc','lead','copper'),155)
m=plotGoogleMaps(a,zcol='col',colPalette=c('red','green','blue') )
# this works for 2 or more variables.
a=pie(meuse,zcol=c('zinc','lead','copper','dist.m'))
a$col=rep(c('zinc','lead','copper','dist.m'),155)
m=plotGoogleMaps(a,zcol='col',colPalette=rainbow(4) )
# you can use it for spplot
a$col=rep(1:4,155)
spplot(a,zcol='col', col.regions=rainbow(4))
# or for plotKML
plotKML(a)
Hope this helps.
Best,
Kili
