Continuous colour filling scales for PHS — scale_fill_continuous

The default continuous colour filling scale for use in PHS

Usage

scale_fill_continuous_phs(
  ...,
  type = "seq",
  palette = 1,
  direction = 1,
  values = NULL,
  space = "Lab",
  na.value = "grey50",
  guide = "colourbar",
  aesthetics = "fill"
)

Arguments

...: Additional parameters passed on to the scale type
type: "seq" (sequential). Please see phs_palette_types for more details.
palette: a number describing which palette to use within that type. Defaulted as 1 referring to the first palette "main-purples" in type "seq". It can also be the actual name of the palette e.g. main-purples. Please see phs_palettes for more details.
direction: either be 1 (following the palette order) or -1 (reversing the palette order). Defaulted as 1.
values: if colours should not be evenly positioned along the gradient this vector gives the position (between 0 and 1) for each colour in the colours vector.
space: colour space in which to calculate gradient. Must be "Lab" - other values are deprecated.
na.value: Missing values will be replaced with this value.
guide: A function used to create a guide or its name. Defaulted as "colourbar".
aesthetics: defaulted as "fill"

Details

There are a list of continuous colour filling scales using interpolated method that can be used for PHS charts, such as interpolating colours for main-purples which contains phs-purple, phs-purple-80, phs-purple-50, phs-purple-30 and phs-purple-10.

Examples

library(ggplot2)
ggplot(faithfuld, aes(waiting, eruptions)) +
geom_raster(aes(fill = density)) +
