Legend for Proportional Lines Maps

Description

Plot legend for proportional lines maps

Usage

legendPropLines(
  pos = "topleft",
  title.txt = "Title of the legend",
  title.cex = 0.8,
  cex = 1,
  values.cex = 0.6,
  var,
  lwd,
  col = "red",
  frame = FALSE,
  values.rnd = 0
)

Arguments

pos	position of the legend, one of "topleft", "top", "topright", "right", "bottomright", "bottom", "bottomleft", "bottomleftextra", "left" or a vector of two coordinates in map units (c(x, y)).
title.txt	title of the legend.
title.cex	size of the legend title.
cex	size of the legend. 2 means two times bigger.
values.cex	size of the values in the legend.
var	vector of values (at least min and max).
lwd	width of the larger line.
col	color of symbols.
frame	whether to add a frame to the legend (TRUE) or not (FALSE).
values.rnd	number of decimal places of the values in the legend.

Examples

library(sf)
mtq <- st_read(system.file("gpkg/mtq.gpkg", package="cartography"))
plot(st_geometry(mtq))
box()
legendPropLines(pos = "topleft", title.txt = "Title",
                title.cex = 0.8, values.cex = 0.6, cex = 1,
                var = c(10,100),
                lwd = 15,
                col="red", frame=TRUE, values.rnd=0)
