Okabe-Ito color palette

Source: R/scale_color_okabeito.R
palette_okabeito.Rd

The palette based proposed by Okabe and Ito (2008).

Usage

palette_okabeito(palette = "full_amber", reverse = FALSE, order = 1:9, ...)

palette_oi(palette = "full_amber", reverse = FALSE, order = 1:9, ...)

Arguments

palette

Character name of palette. Depending on the color scale, can be one of "full", "ice", "rainbow", "complement", "contrast", "light" (for dark themes), "black_first", full_original, or black_first_original. The latter three options are especially for the Okabe-Ito color palette. The default is NULL and either "contrast" or "gradient" is used (depending on whether discrete is TRUE or FALSE), which are the two scale useful for discrete or gradient color scales, respectively.

reverse

Boolean indicating whether the palette should be reversed.

order

A vector of numbers from 1 to 9 indicating the order of colors to use (default: 1:9)

...

Additional arguments to pass to colorRampPalette().

Details

This function is usually not called directly, but from within scale_color_material().
