R Documentation

Add Contour Lines to Gradient Field Heatmap.

Description

Add contour lines of the separate objectives to the heatmap of the cumulated path lengths.

Usage

addGGContour(
  g,
  lower,
  upper,
  fn1,
  fn2,
  fn3,
  log.scale = TRUE,
  col1 = "goldenrod1",
  col2 = "white",
  col3 = "cyan3",
  n.points = 30L,
  ...
)

Arguments

`g`	[`ggplot2::ggplot`] `ggplot`-object as created by `ggplotHeatmap`.
`lower`	[`numeric`] Vector of lower bounds.
`upper`	[`numeric`] Vector of upper bounds.
`fn1`	[`function`] The first objective used for computing the multi-objective gradient.
`fn2`	[`function`] The second objective used for computing the multi-objective gradient.
`fn3`	[function] The third objective (if existing) used for computing the multi-objective gradient.
`log.scale`	[`logical`] Should the resulting heights be displayed on a log-scale? The default is `TRUE`.
`col1`	[`character`] Color used for the contour lines of the first objective (default: `"goldenrod1"`).
`col2`	[`character`] Color used for the contour lines of the second objective (default: `"white"`).
`col3`	[`character`] Color used for the contour lines of the third objective (default: `"cyan3"`).
`n.points`	[`integer`] Number of points used for computing the contour lines. The default is `30L`.
`...`	[any] Further arguments to be passed to the `geom_tile` function of `ggplot`.
