tmap (version 2.2)

tm_sf: Draw simple features

Description

Creates a tmap-element that draws simple features. Basically, it is a stack of tm_polygons, tm_lines and tm_dots. In other words, polygons are plotted as polygons, lines as lines and points as dots.

Usage

tm_sf(col = NA, size = 0.02, shape = 16, lwd = 1, lty = "solid",
  alpha = NA, palette = NULL, border.col = NA, border.lwd = 1,
  border.lty = "solid", border.alpha = NA, group = NA, ...)

Arguments

col

color of the simple features. See the col argument of tm_polygons, tm_lines and tm_symbols.

size

size of the dots. See the size argument tm_symbols. By default, the size is similar to dot size (see tm_dots)

shape

shape of the dots. See the shape argument tm_symbols. By default, dots are shown.

lwd

width of the lines. See the lwd argument of tm_lines

lty

type of the lines. See the lty argument of tm_lines

alpha

transparency number. See alpha argument of tm_polygons, tm_lines and tm_symbols

palette

palette. See palette argument of tm_polygons, tm_lines and tm_symbols

border.col

color of the borders. See border.col argument of tm_polygons and tm_symbols.

border.lwd

line width of the borders. See border.lwd argument of tm_polygons and tm_symbols.

border.lty

line type of the borders. See border.lwd argument of tm_polygons and tm_symbols.

border.alpha

transparency of the borders. See border.alpha argument of tm_polygons and tm_symbols.

group

name of the group to which this layer belongs in view mode. Each group can be selected or deselected in the layer control item. Groups can either be specified as base or overlay groups in tm_view (arguments base.groups and overlay.groups).

...

other arguments passed on to tm_polygons, tm_lines and tm_symbols

Value

tmap-element
