gf_function_2d: Plot functions of two variables

Description

Plot functions of two variables as tile and/or contour plots.

  ylim = NULL,
  ...,
  tile = TRUE,
  contour = TRUE,
  resolution = 50
)
gf_function2d(
  object = NULL,
  fun = identity,
  xlim = NULL,
  ylim = NULL,
  ...,
  tile = TRUE,
  contour = TRUE,
  resolution = 50
)
gf_function_contour(
  object = NULL,
  fun = identity,

Value

A gg plot.

Arguments

object

An R object, typically of class "gg".

fun

A function of two variables to be plotted.

xlim

x limits for generating points to be plotted.

ylim

y limits for generating points to be plotted.

...

additional arguments passed to gf_tile() or gf_contour().

tile

A logical indicating whether the tile layer should be drawn.

contour

A logical indicating whether the contour layer should be drawn.

resolution

A numeric vector of length 1 or 2 specifying the number of grid points at which the function is evaluated (in each dimension).

formula

A formula describing a function of two variables to be plotted. See mosaic::makeFun() for details regarding the conversion from a formula to a function.

Examples

theme_set(theme_bw())
gf_function_2d(fun = function(x, y) sin(2 * x * y), xlim = c(-pi, pi), ylim = c(-pi, pi)) |>
  gf_refine(scale_fill_viridis_c())
gf_function_2d(fun = function(x, y) x + y, contour = FALSE)
gf_function_tile(fun = function(x, y) x * y) |>
  gf_function_contour(fun = function(x, y) x * y, color = "white") |>
  gf_refine(scale_fill_viridis_c())
gf_fun_tile(x * y ~ x + y, xlim = c(-3, 3), ylim = c(-2, 2)) |>
  gf_fun_contour(x * y ~ x + y, color = "white") |>
  gf_refine(scale_fill_viridis_c()) |>
  gf_labs(fill = "product")
