View source: R/tm_layers.R

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.

)

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. Set group = NULL to hide the layer in the layer control item. By default, it will be set to the name of the shape (specified in tm_shape).

...

other arguments passed on to tm_polygons, tm_lines and tm_symbols

Value

tmap-element
