Usage

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

Arguments

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)

Value

No return value, a scale bar is displayed.

Note

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

Examples

mtq <- mf_get_mtq()
mf_map(mtq)
