sm_north: Adds a north symbol to a ggplot map

In samesag/emu: Encuesta de Movilidad Uniandina

Adds a north symbol to a ggplot map

Description

This function inserts a pretty north symbol in a ggplot map

Usage

sm_north(
  data = NULL,
  location = "topleft",
  scale = 0.1,
  symbol = 1,
  x.min,
  x.max,
  y.min,
  y.max,
  anchor = NULL
)

Arguments

data	The dataframe containing the spatial information for the box limits.
location	string indicating the symbol's location in the plot. Possible options: "topleft" (default), "bottomright", "bottomleft" and "topright".
scale	a variable (or vector of variables) quoted that you want to change to binary.
symbol	number between 1 and 3 to choose a symbol (1: black, 2: grey, 3: white)
x.min	if data is not defined, number with the minimum x coordinate. Useful for ggmap.
x.max	if data is not defined, number with the maximum x coordinate. Useful for ggmap.
y.min	if data is not defined, number with the minimum y coordinate. Useful for ggmap.
y.max	if data is not defined, number with the maximum y coordinate. Useful for ggmap.
anchor	named vector with coordinates to control the symbol position. For location = "topright", anchor defines the coordinates of the symbol's topright corner and so forth. The x coordinate must be named as x and the y coordinate as y.

Details

North symbols are included in the plot with the annotation_custom function, which do not works when used together with an empty call to ggplot (see last example). When it is convenient to use an empty call to ggplot, use north2 instead.

Value

The binary answers, changing "no" or "none" to 0 and "yes" to 1.

Examples

## Not run:
library(sf)
data(domestic_violence)
ggplot(domestic_violence, aes(fill = Scaled)) +
geom_sf() +
north_map(domestic_violence, location = "bottomright", symbol = 3) +
scale_fill_continuous(low = "#fff7ec", high = "#7F0000")
