mf_theme()
sets a map theme. A theme is
a set of graphical parameters that are applied to maps created with
mapsf
. These parameters are the figure margins, background
and foreground colors and mf_title()
options.
mapsf
offers some builtin themes. It’s possible to modify
an existing theme or to start a theme from scratch. Themes are
persistent across maps produced by mapsf
(e.g. they survive
a dev.off()
call).
Builtin themes
Here are the builtin themes. We have added a grey background color to
make the margins more visible.
The following table displays the parameters of these themes.
bg | fg | mar | tab | pos | inner | line | cex | font | |
---|---|---|---|---|---|---|---|---|---|

How to modify an existing theme
It is possible to modify an existing theme. In this example we use the “default” theme and modify some title parameters.
How to create a new theme
It is possible to create a new theme.
mf_theme(
bg = "lightblue", fg = "tomato1", mar = c(0, 2, 0, 2),
tab = TRUE, inner = TRUE, line = 1.3, pos = "center",
cex = 1.1, font = 3
)
mf_map(mtq)
mf_title("New theme")
It is also possible to assign a theme to a variable.
