I've tested the effect of the projections on overlaying graphs using
levelplot() + layer()
In short, the user's object must be in epsg:4326, probably because
layer() carries out a reprojection.
The bad news is that it carries out a wrong reprojection, perhaps
because the incorrect

the so-called

Dear all,
I used this code to plot a map.
