crds function

Get the coordinates of SpatVector geometries or SpatRaster cells

Get the coordinates of a SpatVector or SpatRaster cells. A matrix or data.frame of the x (longitude) and y (latitude) coordinates is returned. methods

## S4 method for signature 'SpatVector'
crds(x, df=FALSE, list=FALSE)

## S4 method for signature 'SpatRaster'
crds(x, df=FALSE, na.rm=TRUE, na.all=FALSE)

Arguments

• x: SpatRaster or SpatVector
• df: logical. If TRUE a data.frame is returned instead of a matrix
• list: logical. If TRUE a list is returned instead of a matrix
• na.rm: logical. If TRUE cells that are NA are excluded. Ignored if the SpatRaster is a template with no associated cell values
• na.all: logical. If TRUE cells are only ignored if na.rm=TRUE and their value is NA for all layers instead of for any layer

Returns

matrix or data.frame

geom returns the complete structure of SpatVector geometries. For SpatRaster see xyFromCell
