Draw a map with labeled regions
Like map, but labels the regions.
map.text(database, regions = ".", exact = FALSE, labels, cex = 0.75, add = FALSE, move = FALSE, ...)
database |
character string naming a geographical database, or a list of
|
regions |
character vector that names the polygons to draw. |
exact |
If 'TRUE', only exact matches with 'regions' are selected for drawing. |
labels |
character vector of labels, one for each region selected. Defaults to the names in the database. |
cex |
character expansion factor. |
add |
If |
move |
If |
... |
Other arguments are the same as in |
If add = FALSE, a map is drawn by calling map.
Then the label for each region is placed at the centroid of the region
polygon.
The return value is a map object, as from map.
