## S4 method for signature 'function'
ternary_image(f, n = 48, palette = NULL, ...)

Arguments

f	A function that takes three arguments (x, y and z coordinates) and returns a numeric vector (see tile_bin(), tile_density(), tile_interpolate()).
...	Further parameters to be passed to f.
n	A length-one integer vector specifying the maximum number of tiles on each axis.
palette	A function that takes a single numeric vector (the output of f) as argument and returns a vector of color. If NULL, the default color scheme will be used. If FALSE, the output of f is used as colors.
