Discrete colour and fill scales

Source: R/scales.R
scale_japanesecolors.Rd

Discrete ggplot2 scales using a japanesecolors palette. scale_color_japanesecolors() is an alias for scale_colour_japanesecolors().

Usage

scale_colour_japanesecolors(palette, ..., reverse = FALSE, na.value = "grey50")

scale_color_japanesecolors(palette, ..., reverse = FALSE, na.value = "grey50")

scale_fill_japanesecolors(palette, ..., reverse = FALSE, na.value = "grey50")

Arguments

palette

A palette ID, such as "kawaii_tri_07". See palette_names().

...

Passed on to ggplot2::scale_colour_manual() or ggplot2::scale_fill_manual(), for example name, labels or guide.

reverse

Whether to reverse the colour order.

na.value

Colour used for missing values.

Value

A ggplot2 scale, to add to a plot.

Details

Palettes are curated categorical sets and are used in their printed order. If the data have more levels than the palette has colours, ggplot2 raises an error rather than recycling or interpolating; use palettes() with the n argument to find a palette large enough.
