Chromosome color scale — scale_color_chromosome • ggwas

Alternating color scale for chromosomes in Manhattan plots.

Usage

scale_color_chromosome(
  colors = c("#1A5276", "#76D7C4"),
  chromosomes = NULL,
  ...
)

scale_fill_chromosome(
  colors = c("#1A5276", "#76D7C4"),
  chromosomes = NULL,
  ...
)

Arguments

colors: Two-element character vector of alternating colors.
chromosomes: Chromosome codes present in the data, in the order they appear along the genome. Colors alternate across this set, so any organism is handled (e.g. cattle with 29 autosomes plus X coded as 30). When NULL, defaults to the human coding (autosomes 1-22 plus X/Y/XY/MT as 23-26).
...: Additional arguments passed to ggplot2::scale_color_manual().

Value

A ggplot2 color scale.

Examples

data(example_gwas)
manhattan_plot(example_gwas, colors = c("#E64B35", "#4DBBD5"))
