set
Which palette set (see Details).
alpha
0 for maximum transparency, 1 for no transparency.
func
if TRUE, the returned object will be a function rather than
a character vector
Value
Either a character vector, or, when the func parameter is TRUE,
a function that takes only one argument (a single number)
Details
A few palettes have been predefined in tmod, and this function can be
used to extract them. The following palettes have been defined:
* friendly -- a set of distinct, colorblind-friendly colors
* bwr, rwb, ckp, pkc -- gradients (b-blue, r-red, w-white, c-cyan, k-blacK, p-purple)
By default, either all colors are returned, or, if it is a gradient
palette, only three.
Yes, I wrote this function to save myself the slightest amount of typing.
