Generate hexadecimal color vectors for use in plotting based on popular color
palettes and packages. Default is 100 viridis colors.
[continuous palettes] n colors are pulled from the desired palette
[discrete palettes] pulls n colors from discrete palette. If the
number of colors requested is within the number of discrete colors,
the values will be pulled without modification starting from the first
value. If more are requested than exist then the palette will be made
continuous
Usage
getColors(
pal = "viridis",
n = 100,
rev = FALSE,
src = NULL,
strategy = c("interpolate")
)Arguments
- pal
