GoogleMapsCoordinates function

Google Maps with marked coordinates

Google Maps with marked coordinates.

GoogleMapsCoordinates(Longitude,Latitude,Cls=rep(1,length(Longitude)),
zoom=3,location= c(mean(Longitude),mean(Latitude)),stroke=1.7,size=6,sequence)

Arguments

• Longitude: sphaerischer winkel der Kugeloberflaeche, coord 1
• Latitude: sphaerischer winkel der Kugeloberflaeche, coord 2
• Cls: Vorklassification/Clusterung
• zoom: map zoom, an integer from 3 (continent) to 21 (building), default value 10 (city). openstreetmaps limits a zoom of 18, and the limit on stamen maps depends on the maptype. "auto" automatically determines the zoom for bounding box specifications, and is defaulted to 10 with center/zoom specifications. maps of the whole world currently not supported
• location: Optional, default: c(mean(Longitude),mean(Latitude); an address, longitude/latitude pair (in that order), or left/bottom/right/top bounding box
• stroke: Optional, plotting parameter, dicke der linien der coordiantensymbole
• size: Optional, plotting parameter, groesse der koordinatensymbole
• sequence: Optional, vector of length of number of clusers with numbers indicating the plotting symbols and colors to use

Returns
