Mosaics with flexible Truchet tiles

Usage

st_truchet_fm(
  df = NULL,
  tiles = c("Al", "Cl"),
  b = 1/2,
  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), b (control of the boundary; defaults to 1/2)

tiles

a character vector with types of tiles to use for mosaic (default: c("dr", "dl"))

b

A number between zero and one that controls the shape of the boundary between the two parts of the tile

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
