New release of maplegend: version 0.6.3

maplegend is a package for creating legends for maps and other graphics.

This release introduces several changes. The main ones are the improvement of the proportionnal symbols display and the addition of four new legend types:

• choropleth legend on circles or squares
• choropleth legend on lines
• choropleth legend on symbols
• typology legend on lines.

Other changes are bug fixes and minor improvements.

Proportionnal symbols

png("legend.png", width = 150, height = 150, res = 110)
library(maplegend)
par(mar = c(1,1,1,1))
plot(0, ann = FALSE, axes = FALSE, pch = NA)
leg(type = "prop", val = c(10, 50, 100), inches = .35, pos = "top", 
    title = "v0.6.3", col = "#940000", border = "grey90", fg = "black", lwd = 1)
dev.off()

New legend types

library(maplegend)
plot(0, ann = FALSE, axes = FALSE, pch = NA)
# choropleth legends on circles or square
leg(type = "choro_point", val = seq(0, 100, 20), pos = "topleft", pal = 'Burg', 
    cex = 1, val_rnd = 0, symbol = "circle", title = "type = 'choro_point'")
leg(type = "choro_point", val = seq(0, 100, 20), pos = "topleft", pal = 'Burg', 
    cex = 1, val_rnd = 0, symbol = "square", title = "       ", adj = c(15, 0))
# choropleth legend on lines
leg(type = "choro_line", val = c(10, 20, 30, 40, 50), pos = "topright", 
    pal = 'Teal', lwd = 5, val_rnd = 0, no_data = TRUE, no_data_txt = "No data",
    title = "type = 'choro_line'")
# choropleth legend on symbols
leg(type = "choro_symb", val = c(10, 20, 30, 40, 50), pch = 24, pal = "Rocket", 
    pos = "bottomleft", cex = 2, val_rnd = 1, lwd = 1,  
    title = "type = 'choro_symb'")
# typology legend on lines
leg(type = "typo_line", val = c("A", "B", "C"), lwd = 4, pos = "bottomright", 
    pal = c("#da131a", "#ffb915", "#007847"), no_data = TRUE, col_na = "white",  
    frame = TRUE, bg = "#292421", fg = "white", frame_border = NA, 
    box_cex = c(2, 1), title = "type = 'typo_line'")
