Plot a scale bar.
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)
mf_scale()
