In rspatial/terra: Spatial Data Analysis

Map panel

Description

Show multiple maps that share a single legend.

Usage

## S4 method for signature 'SpatRaster'
panel(x, main, loc.main="topleft", nc, nr, maxnl=16, 
	maxcell=500000, box=FALSE, pax=list(), plg=list(), range=NULL, ...)

Arguments

x	SpatRaster
main	character. Main plot titles (one for each layer to be plotted). You can use arguments cex.main, font.main, col.main to change the appearance
loc.main	numeric of character to set the location of the main title. Either two coordinates, or a character value such as "topleft")
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)
maxnl	positive integer. Maximum number of layers to plot (for a multi-layer object)
maxcell	positive integer. Maximum number of cells to use for the plot
box	logical. Should a box be drawn around the map?
plg	see plot
pax	see plot
range	numeric. minimum and maximum values to be used for the continuous legend
...	arguments passed to plot("SpatRaster", "numeric") and additional graphical arguments

Examples

 
r <- rast(system.file("ex/elev.tif", package="terra"))
v <- vect(system.file("ex/lux.shp", package="terra"))
x <- c(r, r/2, r*2, r)
names(x) <- paste0("(", LETTERS[1:4], ")")
panel(x)
panel(x, fun=\()lines(v), loc.main="topright")
