directly transform a set of coordinates

sf_project(
  from,
  to,
  pts,
  keep = FALSE,
  warn = TRUE,
  authority_compliant = st_axis_order()
)

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; TRUE means handle axis order authority compliant (e.g. EPSG:4326 implying x=lat, y=lon), FALSE means use visualisation order (i.e. always x=lon, y=lat)

Value

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