st_truchet_ms: Truchet mosaics

In paezha/truchet: Package for creating Truchet tiles and random mosaics

Truchet mosaics

Description

Truchet mosaics

Usage

st_truchet_ms(
  df = NULL,
  p1 = 1,
  p2 = 0,
  p3 = 0,
  tiles = c("dr", "dl"),
  xlim = c(1, 3),
  ylim = c(1, 6)
)

Arguments

df	an (optional) data frame with the following columns: x and y (the coordinates of the tiles in a 1 by 1 grid), tiles (characters with types of tiles to use for mosaic), scale_p (the scale of the tile to be placed at each coordinate)
p1	a number between 0 and 1 with the proportion of spots in the mosaic to cover with tiles of scale 1 (the sum of p1, p2, p3 must be equal to one, or less to avoid empty spots in the mosaic)
p2	a number between 0 and 1 with the proportion of spots in the mosaic to cover with tiles of scale 1/2
p3	a number between 0 and 1 with the proportion of spots in the mosaic to cover with tiles of scale 1/4
tiles	a character vector with types of tiles to use for mosaic (default: c("dr", "dl"))
xlim	a numeric vector of length 2 giving the range of the x coordinates of the mosaic (ignored if argument df is an input)
ylim	a numeric vector of length 2 giving the range of the y coordinates of the mosaic (ignored if argument df is an input)

Value

An object of type sf with the tiles arranged as a mosaic

Examples

mosaic <- st_truchet_ms()
plot(mosaic)
mosaic <- st_truchet_ms(p1 = 0.8, p2 = 0.16, p3 = 0.04)
plot(mosaic)
mosaic <- st_truchet_ms(p1 = 0.6, p2 = 0.3, p3 = 0.1, tiles = c("|", "-"))
plot(mosaic)
