Plot a scale bar — mf_scale • mapsf

Plot a scale bar.

Usage

mf_scale(size, pos = "bottomright", lwd = 1.5, cex = 0.6, col, unit = "km")

size: size of the scale bar in units (default to km). If size is not set, an automatic size is used (1/10 of the map width)
pos: position. It can be one of 'bottomright', 'bottomleft', 'interactive' or a vector of two coordinates in map units (c(x, y)).
lwd: width of the scale bar
cex: cex of the text
col: color
unit: units used for the scale bar. Can be "mi" for miles, "m" for meters, or "km" for kilometers (default)

No return value, a scale bar is displayed.

This scale bar does not work on unprojected (long/lat) maps.

mtq <- mf_get_mtq()
