how to create a shape file from a polygone
Dear R-users,
I have created a map with plot location using longitude/latitude coordinates
with the PlotOnStaticMap() function of the RgoogleMaps package. Everything
works fine until I try to put a polygon on the map. The polygon() function
doesn?t work and I need to use the special function PlotPolysOnStaticMap()
however this requires a shapefile (which I'm not sure what it is) and not XY
coordinates.
So my question is quite simple: How do I transform XY (lon/lat) coordinates
into a shape file.
My polygon:
x.pol.mat<-c(-66.67,-66.46,-66.54,-66.82,-67.06,-66.97)
y.pol.mat<-c(48.87,48.89,48.745...
