Generate viridis or other color code for continuous values
spec_color(
x,
alpha = 1,
begin = 0,
end = 1,
direction = 1,
option = "D",
na_color = "#BBBBBB",
scale_from = NULL,
palette = viridisLite::viridis(256, alpha, begin, end, direction, option)
)
continuous vectors of values
The alpha transparency, a number in [0,1],
The (corrected) hue in [0,1] at which the color map begins.
The (corrected) hue in [0,1] at which the color map ends.
Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed.
A character string indicating the color map option to use. Eight options are available: "magma" (or "A"), "inferno" (or "B"), "plasma" (or "C"), "viridis" (or "D"), "cividis" (or "E"), "rocket" (or "F"), "mako" (or "G") and "turbo" (or "H").
color code for NA values
input range (vector of length two). If not given, is calculated from the range of x
The palette to use as a character vector of colors. If
this is specified, parameters other than x
, na_color
and scale_from
are ignored.
