Arguments

from

character description of source CRS, or object of class crs

to

character description of target CRS, or object of class crs

pts

two-column numeric matrix, or object that can be coerced into a matrix

keep

logical value controlling the handling of unprojectable points. If `keep` is `TRUE`, then such points will yield `Inf` or `-Inf` in the return value; otherwise an error is reported and nothing is returned.

warn

logical; if TRUE, warn when non-finite values are generated

authority_compliant

logical; handle axis order authority compliant (e.g. EPSG:4326 has x=lat, y=lon) or use visualisation order (x=lon, y=lat)

Value

two-column numeric matrix with transformed/converted coordinates, returning invalid values as Inf
