Colour and fill scales using colours from the e61 palette

The colour and fill scales are designed for discrete scales. If the data are continuous, we recommend binning the data as this often makes it easier to distinguish between values than a continuous scale. If a continuous scale is desired, the discrete argument can be set to FALSE.

Usage

scale_colour_e61(
  reverse = FALSE,
  discrete = TRUE,
  aesthetics = "colour",
  palette = c("light", "dark", "diverging", "grey"),
  n = NULL,
  ...
)

scale_fill_e61(
  reverse = FALSE,
  discrete = TRUE,
  aesthetics = "fill",
  palette = c("light", "dark", "diverging", "grey"),
  n = NULL,
  ...
)

Arguments

reverse

Logical. TRUE reverses the colour order. Defaults to FALSE.

discrete

Logical. Indicate whether to use a discrete scale. Defaults to TRUE.

palette

Character. The specific e61 palette for continuous scales. Must be supplied if a continuous scale is used.

n

n is no longer used.

Arguments passed on to ggplot2::scale_colour_manual

values

a set of aesthetic values to map data values to. The values will be matched in order (usually alphabetical) with the limits of the scale, or with breaks if provided. If this is a named vector, then the values will be matched based on the names instead. Data values that don't match will be given na.value.

aesthetics

Character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with. This can be useful, for example, to apply colour settings to the colour and fill aesthetics at the same time, via aesthetics = c("colour", "fill").

breaks

One of:

NULL for no breaks
waiver() for the default breaks (the scale limits)
A character vector of breaks
A function that takes the limits as input and returns breaks as output

na.value

The aesthetic value to use for missing (NA) values

Value

ggplot2 object
