Source: R/pg_coords_from_id.R
pg_coords_from_id.Rd

Returns the centre coordinates of cells in a configured PRIO-GRID.

Usage

pg_coords_from_id(
  pgid,
  crs = 4326,
  invalid = c("error", "NA"),
  config = priogrid::pg_current_config()
)

Arguments

pgid

Numeric vector of PRIO-GRID cell IDs.

crs

Coordinate reference system for the returned coordinates. Any value accepted by sf::st_crs() may be used.

invalid

How unknown or missing IDs should be handled: raise an error or return missing coordinates.

config

A PRIO-GRID configuration object.

Value

A data frame with pgid, xcoord, and ycoord.

Examples

config <- priogrid::pg_config(nrow = 18, ncol = 36)
pg_coords_from_id(1:3, config = config)
#>   pgid xcoord ycoord
#> 1    1   -175    -85
#> 2    2   -165    -85
#> 3    3   -155    -85
