crds: Get the coordinates of SpatVector geometries or SpatRaster cells

Description

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

Usage

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

Value

matrix or data.frame

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

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

Examples

x1 <- rbind(c(-175,-20), c(-140,55), c(10, 0), c(-140,-60))
x2 <- rbind(c(-125,0), c(0,60), c(40,5), c(15,-45))
x3 <- rbind(c(-10,0), c(140,60), c(160,0), c(140,-55))
x4 <- rbind(c(80,0), c(105,13), c(120,2), c(105,-13))
z <- rbind(cbind(object=1, part=1, x1), cbind(object=2, part=1, x2), 
           cbind(object=3, part=1, x3), cbind(object=3, part=2, x4))
colnames(z)[3:4] <- c('x', 'y')
z <- cbind(z, hole=0)
z[(z[, "object"]==3 & z[,"part"]==2), "hole"] <- 1

p <- vect(z, "polygons")
crds(p)

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
g <- crds(v)
