I see function *segmentGoogleMaps* from package *plotGoogleMaps* does
exactly what I need with data from dataset *meuse*.
When I ran code:
coordinates(sampledf)<-~x+y # convert to SPDF
proj4string(sampledf) <- CRS('+init=epsg:28992')# adding Coordinate
Referent Sys.
# Create web map of Point data
m<-plotGoogleMaps(sampledf,filename='myMap1.htm')
Everything works just fine. When I try to run code:
# colPalette defines colors for plot
m<-segmentGoogleMaps(sampledf, zcol=c('City','Village'),
mapTypeId='ROADMAP',
filename='myMap4.htm',colPalette=c('#E41A1C','#377EB8'),
strokeColor='black')
everything goes wrong and all points seems to show in one single
coordinate pair.
The problem is I think that data in meuse dataset are different from
mine (I think UTM).
When tried to convert same result.
I desperately need to see pie chart in a google map so please help
solving this issue
Whoa! All bets are off! plotGoogleMaps generates overlays on an HTML
page linked to Google Maps. This is way off what you do with R graphics
devices. Your best bet is to search:
pie chart google maps
on Google and start reading. I have used plotGoogleMaps, but never put
pie charts on them, and I really don't have time to learn how at the moment.
