Add SpatVector data to a map

Description

Add SpatVector data to a plot (map) with points, lines, or polys.

These are simpler alternatives for plot(x, add=TRUE)

Usage

## S4 method for signature 'SpatVector'
points(x, col, cex=1, pch=20, ...)

## S4 method for signature 'SpatVector'
lines(x, y=NULL, col, lwd=1, lty=1, arrows=FALSE, ...)

## S4 method for signature 'SpatVector'
polys(x, col, border="black", lwd=1, lty=1, ...)

## S4 method for signature 'SpatExtent'
points(x, col, ...)

## S4 method for signature 'SpatExtent'
lines(x, col, ...)

Arguments

x

SpatVector or SpatExtent
y

missing or SpatVector. If both x and y have point geometry and the same number of rows, lines are drawn between pairs of points
col

character. Colors
border

character. color(s) of the polygon borders. Use NULL or NA to not draw a border
cex

numeric. point size magnifier. See par
pch

positive integer, line type. See points
lwd

numeric, line-width. See par
lty

positive integer, line type. See par
arrows

logical. If TRUE and y is a SpatVector, arrows are drawn intead of lines. See ?arrows for additional arguments
...

additional graphical arguments such as lwd, cex and pch

Examples

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

r <- rast(v)
values(r) <- 1:ncell(r)
plot(r)
lines(v)
points(v)
