Hi all,
I'm faced with a problem applying the sp package: The projection argument in
readShapePoly(Shapefile,proj4string="CRS class argument")
e.g.: CRS("+proj=aea +lat_1=46 +lat_2=73 +lat_0=60 +lon_0=84 +x_0=0
+y_0=0 +ellps=clrk66 +units=m +no_defs")
doesn't have any impact on the plotted object. I also tested the simple
example:
xy = cbind(x = 2 * runif(100) - 1, y = 2 * runif(100) - 1)
plot(SpatialPoints(xy, proj4string =
CRS("+proj=longlat")),xlim=c(-1,1),ylim=c(-1,1))
looks exactly like
plot(SpatialPoints(xy, proj4string =CRS("+proj=stere +lon_0=98 +over"))
or
plot(SpatialPoints(xy))
without any projection.
What I'm doing wrong?
I use the latest versions of sp and rgdal.
With many thanks for any hint,
