It 's not a reprex.
I have maps with very long titles. I put my legend them outside. The font size is very small and I can't control it. The argument title.size = 2
is not working.
map_cp <- tm_shape(choro) +
tm_polygons(col = "taux", style = "jenks",
legend.hist = TRUE) +
tm_borders("#9E9E9E") +
tm_shape(sgf_centro) +
tm_symbols(col = "#f50057", alpha = 0.1, border.col = "#f50057",
size = centro_var,
perceptual = TRUE,
scale = 2) +
tm_layout(title = label$LIBELLE, title.size = 0.6,legend.outside = TRUE)
