tm_credits

0th

Percentile

Credits text

Creates a text annotation that could be used for credits or acknowledgements.

Usage
tm_credits(text, size = 0.7, col = NA, alpha = NA, align = "left",
  bg.color = NA, bg.alpha = NA, fontface = NA, fontfamily = NA,
  position = NA, just = NA)
Arguments
text

text. Multiple lines can be created with the line break symbol "\n". Facets can have different texts: in that case a vector of characters is required. Use "" to omit the credits for specific facets.

size

relative text size

col

color of the text. By default equal to the argument attr.color of tm_layout.

alpha

transparency number between 0 (totally transparent) and 1 (not transparent). By default, the alpha value of col is used (normally 1).

align

horizontal alignment: "left" (default), "center", or "right". Only applicable if text contains multiple lines

bg.color

background color for the text

bg.alpha

Transparency number between 0 (totally transparent) and 1 (not transparent). By default, the alpha value of the bg.color is used (normally 1).

fontface

font face of the text. By default, determined by the fontface argument of tm_layout.

fontfamily

font family of the text. By default, determined by the fontfamily argument of tm_layout.

position

position of the text. Vector of two values, specifing the x and y coordinates. Either this vector contains "left", "LEFT", "center", "right", or "RIGHT" for the first value and "top", "TOP", "center", "bottom", or "BOTTOM" for the second value, or this vector contains two numeric values between 0 and 1 that specifies the x and y value of the center of the text. The uppercase values correspond to the position without margins (so tighter to the frame). The default value is controlled by the argument "attr.position" of tm_layout.

just

Justification of the attribute relative to the point coordinates. The first value specifies horizontal and the second value vertical justification. Possible values are: "left" , "right", "center", "bottom", and "top". Numeric values of 0 specify left/bottom alignment and 1 right/top alignment. This option is only used, if position is specified by numeric coordinates. The default value is controlled by the argument "attr.just" of tm_layout.
