### Usage

from_coord_polygon(coord, carto)


### Arguments

 coord a vector of length 2 or a two columns matrix containing xy coordinates to transform carto a cartogramR object

### Value

a vector of length 2 or a two columns matrix containing xy coordinates in the coordinate systems of polygons used to build the cartogram

data(usa)
carto <- cartogramR(usa, "electors64")
from_coord_polygon(c(-0.007, -0.348), carto)
