Hi
to all,
I
need to automatically set the geographical coordinates of the projection’s
centre to project different polygons in different territories. My problem is the
following.
By
using spTransform(xy, CRS("+proj=laea +lat_0=LAT +lon_0=LONG +x_0=0 +y_0=0
+ellps=WGS84 +units=m +no_defs")),  I would like to set  +lat_0 and +long_0 as objects (here “LAT” and
“LONG”) that I automatically generated. Unfortunately, this function doesn’t
read objects (even if “as.numeric”) but only numerical values set manually. Is
there a way to set these coordinates as objects?
Many
thanks.
