Returns a viridisLite spec (option, begin, end, direction) for a
sequential gradient. Use directly with ggplot2::scale_*_viridis_c() or
via scale_fill_a11y_seq(). Pass n = to materialize hex codes.
Usage
a11y_palette_seq(name = "cividis", n = NULL)
Arguments
- name
One of "cividis" (default), "viridis",
"plasma".
- n
Optional integer. If supplied, returns n hex codes from the
gradient instead of the spec.
Value
Named list with elements option, begin, end, direction –
a viridisLite specification, NOT a color vector. Pass n = to
materialize hex codes.
Examples
a11y_palette_seq("cividis")
#> $option
#> [1] "cividis"
#>
#> $begin
#> [1] 0
#>
#> $end
#> [1] 1
#>
#> $direction
#> [1] 1
#>
a11y_palette_seq("viridis", n = 7)
#> [1] "#440154FF" "#443A83FF" "#31688EFF" "#21908CFF" "#35B779FF" "#8FD744FF"
