plotVector: Plot a SpatVector

Description

Plot SpatVector data to make a map

Usage

# S4 method for SpatVector,character
plot(x, y, col, type, mar=NULL, legend=TRUE,
     add=FALSE, axes=!add, main=y,
     plg=list(), pax=list(), nr, nc, ...)
# S4 method for SpatVector,numeric
plot(x, y, ...)
# S4 method for SpatVector,missing
plot(x, y, ...)
# S4 method for SpatExtent,missing
plot(x, y, ...)

Arguments

x

SpatVector

y

missing or positive integer indicating the layer(s) to be plotted, or the name of the layer

col

character. Colors

type

character. Type of map/legend. One of "none", "continuous", "classes", "interval"

mar

numeric vector of lenght 4 to set the margins of the plot (to make space for the legend). The default is c(3.1, 3.1, 2.1, 7.1) for a plot with a legend. Use mar=NA to not set the margins

legend

logical. Draw a legend?

add

logical. If TRUE add the object to the current plot

axes

logical. Draw axes?

main

character. Text for the main title of the plot

plg

list with parameters for drawing the legend. See the arguments for legend

pax

list with parameters for drawing axes. See the arguments for axis

nc

positive integer. Optional. The number of columns to divide the plotting device in (when plotting multiple layers)

nr

positive integer. Optional. The number of rows to divide the plotting device in (when plotting multiple layers)

...

additional arguments passed to plot("SpatVector", "character") method, and graphical arguments such as lwd, cex and pch

# NOT RUN {
f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)

plot(v)

plot(v, 2, pax=list(sides=1:2), plg=list(x=6.2, y=50.2, cex=1.2))

plot(v, 4, pax=list(sides=1:2), plg=list(x=6.2, y=50.2, ncol=2), main="")
 
plot(v, 1, plg=list(x=5.9, y=49.37, horiz=TRUE, cex=1.1), main="", mar=c(5,2,0.5,0.5))

plot(v, density=1:12, angle=seq(18, 360, 20), col=rainbow(12))

plot(v, "NAME_2", col=rainbow(12), border=c("gray", "blue"), lwd=3, type="classes")

plot(v, "AREA", type="interval", breaks=3, mar=c(3.1, 3.1, 2.1, 3.1),
  plg=list(x="topright"), main="")

plot(v, "AREA", type="interval", breaks=c(0,200,250,350), mar=c(2,2,2,2), 
  plg=list(legend=c("<200", "200-250", ">250"), cex=1, 
  bty="o", x=6.4, y=50.125, box.lwd=2, bg="light yellow", title="My Legend"))
