In jrboyd/seqsetvis: Set Based Visualizations for Next-Gen Sequencing Data

safeBrew

Description

Allows RColorBrew to handle n values less than 3 and greater than 8 without warnings and return expected number of colors.

Usage

safeBrew(n, pal = "Dark2")

Arguments

n	integer value of number of colors to make palette for. Alternatively a character or factor, in which case palette will be generated for each unique item or factor level repsectively.
pal	palette recognized by RColorBrewer

Details

For convenience, instead of the number n requested, n may be a character or factor vector and outputs will be appropriately named for use with scale_color/fill_manual.

Additionally, accepts pal as "gg", "ggplot", or "ggplot2" to reproduce default ggplot colors in the same way.

Value

a character vector of hex coded colors of length n from the color brewer palette pal. If n is supplied as character or factor, output will be named accordingly.

Examples

plot(1:2, rep(0, 2),  col = safeBrew(2, "dark2"), pch = 16, cex = 6)
plot(1:12, rep(0, 12),  col = safeBrew(12, "set1"), pch = 16, cex = 6)
plot(1:12, rep(0, 12),  col = safeBrew(12, "set2"), pch = 16, cex = 6)
plot(1:12, rep(0, 12),  col = safeBrew(12, "set3"), pch = 16, cex = 6)
