gzAzymuth() in the maptools package is for geographical coordinates, as
its help page says, and yours seem to be projected.

Hello,
I have four doubts:
1)
why gzAzymuth is giving me Northern direction in this case, for example?
require(sp); require(rgdal)
kk=data.frame(x=c(575552.8,576295.9), y=c(4103900,4103611))
coordinates(kk)=~x+y
plot(kk, typ="o", col=4)
gzAzimuth(coordinates(kk)[1,], coordinates(kk)[2,])
2) h
