In tmap: Thematic Maps

Map component: logo

Description

Map component that adds a logo.

Usage

tm_logo(
  file,
  height,
  margins,
  between_margin,
  stack,
  position,
  frame,
  frame.lwd,
  frame.r,
  group.frame,
  resize_as_group,
  z
)

Arguments

file	either a filename or url of a png image. If multiple files/urls are provided with a character vector, the logos are placed near each other. To specify logos for small multiples use a list of character values/vectors. In order to stack logos vertically, multiple tm_logo elements can be stacked.
height	height of the logo in number of text line heights. The width is scaled based the height and the aspect ratio of the logo. If multiple logos are specified by a vector or list, the heights can be specified accordingly.
margins	margins
between_margin	Margin between
stack	stack with other map components, either "vertical" or "horizontal".
position	An object created with tm_pos_in() or tm_pos_out(). Or, as a shortcut, a vector of two values, specifying the x and y coordinates. The first is "left", "center" or "right" (or upper case, meaning tighter to the map frame), the second "top", "center" or "bottom". Numeric values are also supported, where 0, 0 means left bottom and 1, 1 right top. See also vignette about positioning.
frame	frame
frame.lwd	frame line width
frame.r	Radius of the rounded frame corners. 0 means no rounding.
group.frame	group.frame
resize_as_group	resize_as_group
z	z
