## Legend for Double Proportional Triangles Maps

### Description

Plot legends for double proportional triangles maps.

### Usage

legendPropTriangles(
pos = "topleft",
title.txt,
var.txt,
var2.txt,
title.cex = 0.8,
cex = 1,
values.cex = 0.6,
var,
var2,
r,
r2,
col = "red",
col2 = "blue",
frame = FALSE,
values.rnd = 0,
style = "c"
)


### Arguments

 pos position of the legend, one of "topleft", "top", "topright", "right", "bottomright", "bottom", "bottomleft", "left" or a vector of two coordinates in map units (c(x, y)). title.txt title of the legend. var.txt name of var. var2.txt name of var2. 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 a first vector of positive values. var2 a second vector of positive values. r a first vector of sizes. r2 a second vector of sizes. col color of symbols. col2 second 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. style either "c" or "e". The legend has two display styles, "c" stands for compact and "e" for extended.

### Examples

library(sf)
mtq <- st_read(system.file("gpkg/mtq.gpkg", package="cartography"))
plot(st_geometry(mtq))
box()
var <- runif(10, 0,100)
var2 <- runif(10, 0,100)
r <- sqrt(var)*1000
r2 <- sqrt(var2)*1000
legendPropTriangles(pos = "topright", var.txt = "population 1",
var2.txt = "population 2", title.txt="Population totale",
title.cex = 0.8, values.cex = 0.6, cex = 1,
var = var, var2 = var2, r = r, r2 = r2,
col="green", col2="yellow", frame=TRUE, values.rnd=2,
style="c")
