gnomeR colors can be accessed and used in plotting
gnomer_palette(name = "pancan", n, type = c("discrete", "continuous"))
name |
Name of desired palette, supplied in quotes. Choices are: "pancan" (default) (best for discrete), "main" (better for discrete), "sunset" (continuous) |
n |
Number of colors desired. If omitted, uses all colors, or the needed number of colors if less than the total. |
type |
Either "continuous" or "discrete". Use continuous if you want to automatically interpolate between colours. @importFrom graphics rgb rect par image text @importFrom grDevices colorRampPalette |
A vector of colours.
