[R-sig-Geo] resolution of openmap() raster layers

[Agustin Lobo]

Is there any way to download the raster layers
of openmap() with an increased resolution?
I find the quality of the labels very low,
or am I doing something wrong? i.e.

require(raster)
require(mapmisc)
nica <- getData("GADM", country="NIC", level=0)
nicabg <- openmap(nica, path="landscape")
plot(nicabg)

Thanks

Agus
