Truchet tiles made with polygons

Usage

st_truchet_p(x = 0, y = 0, type = "dl", scale_p = 1)

Arguments

x: A number with the x coordinate of the center of the tile
y: A number with the y coordinate of the center of the tile
type: A single character to designate a type of tile; currently supported options are "dl", "dr", "-", "|", "+.", "+", "x.", "tn", "fnw", "fne", "fsw", "fse", "ane", "asw"
scale_p: A number to designate the scale of the tile; currently supported options are 1, 1/2, and 1/4

Value

A list with one or more objects of type sf representing one or more tiles depending on type
