Put labels on a map.
Usage
mf_label(
x,
var,
col,
cex = 0.7,
overlap = TRUE,
lines = TRUE,
halo = FALSE,
bg,
r = 0.1,
q = 1,
...
)Arguments
- x
object of class
sf- var
name(s) of the variable(s) to plot
- col
labels color, it can be a single color or a vector of colors
- cex
labels cex, it can be a single size or a vector of sizes
- overlap
if FALSE, labels are moved so they do not overlap.
- lines
if TRUE, then lines are plotted between x,y and the word, for those words not covering their x,y coordinate
- halo
if TRUE, a 'halo' is displayed around the text and additional arguments bg and r can be modified to set the color and width of the halo.
- bg
halo color, it can be a single color or a vector of colors
- r
width of the halo, it can be a single value or a vector of values
- q
quality of the non overlapping labels placement. Possible values are 0 (quick results), 1 (reasonable quality and speed), 2 (better quality), 3 (insane quality, can take a lot of time).
- ...
further text arguments.
Examples
mtq <- mf_get_mtq()
mf_map(mtq)
mtq$cex <- c(rep(.8, 8), 2, rep(.8, 25))
mf_label(
x = mtq, var = "LIBGEO",
col = "grey10", halo = TRUE, cex = mtq$cex,
overlap = FALSE, lines = FALSE
)
