Source: R/discrete-igv.R

See pal_igv() for details.

scale_color_igv(palette = c("default", "alternating"), alpha = 1, ...)

scale_colour_igv(palette = c("default", "alternating"), alpha = 1, ...)

scale_fill_igv(palette = c("default", "alternating"), alpha = 1, ...)

Arguments

palette

Palette type. There are two available options:

  • "default" (51-color palette).

  • "alternating" (2-color palette).

alpha

p1 + scale_color_igv()
#> `geom_smooth()` using formula = 'y ~ x'

p2 + scale_fill_igv()


p1 + ggplot2::scale_colour_manual(
  values = rep(pal_igv("alternating")(2), times = 3)
)
#> `geom_smooth()` using formula = 'y ~ x'

p2 + ggplot2::scale_fill_manual(
  values = rep(pal_igv("alternating")(2), times = 3)
