scale_edge_fill_highcontrast(..., reverse = FALSE, aesthetics = "edge_fill")
A discrete scale.
Arguments passed to ggplot2::discrete_scale()
.
A logical
scalar. Should the resulting
vector of colors be reversed?
A character
string or vector of character
strings listing the name(s) of the aesthetic(s) that this scale works with.
The qualitative color schemes are used as given (no interpolation): colors are picked up to the maximum number of supported values.
According to Paul Tol's technical note, the bright
, highcontrast
,
vibrant
and muted
color schemes are color-blind safe. The
mediumcontrast
color scheme is designed for situations needing color
pairs.
The light
color scheme is reasonably distinct for both normal or
colorblind vision and is intended to fill labeled cells.
The pale
and dark
schemes are not very distinct in either normal or
colorblind vision and should be used as a text background or to highlight
a cell in a table.
Refer to the original document for details about the recommended uses (see references).
