Rainbow categorical colors across multiple groups

Rainbow categorical colors across multiple groups

rainbowJamMulti(ns, do_plot = FALSE, ...)

Arguments

ns

integer vector of n values passed to rainbowJam().

do_plot

logical indicating whether to plot the result using jamba::showColors().

...

additional arguments are passed to rainbowJam().

Value

list of categorical colors, length equal to the input length(ns), with color vectors with lengths ns.

Details

This function applies colorjam::rainbowJam() to multiple vectors, such that the categorical colors are not duplicated, and are assigned as well-spaced across the rainbow for each group as possible.

Examples

opar <- par("mfrow"=c(3, 1));
on.exit(par(opar));
ns <- c(A=8, B=3, C=4);
colorlist1 <- rainbowJamMulti(ns,
   do_plot=TRUE,
   main="rainbowJamMulti()");


# basic assignment in order
colorset2 <- colorjam::rainbowJam(sum(ns));
colorlist2 <- split(colorset2, rep(seq_along(ns), ns))
jamba::showColors(colorlist2, main="sequential assignment")


# re-assign the same colors
colorlist3 <- lapply(ns, colorjam::rainbowJam);
jamba::showColors(colorlist3, main="independent color assignment");

par(opar);
