proj_trans: Transform coordinates

In paleolimbot/rlibproj: Generic Coordinate Transformation Library ('PROJ') R API

Description

Transform coordinates

Usage

proj_trans(pj, coord, direction = "fwd", verbose = FALSE)

Arguments

pj	A PROJ object or definition coerced using as_proj().
coord	A matrix with four columns (x, y, z, t)
direction	One of "fwd", "ident", or "inv".
verbose	Use FALSE to keep log output during transforms. This is usually not what you want, since you might be transforming millions of coordinates (which may result in millions of log messages).

Value

A transformed value of coord

Examples

p <- proj_create_crs_to_crs("OGC:CRS84", "EPSG:3857")
x <- proj_coord(-64, 45)
proj_trans(p, x)
