The GSEA GenePattern color scales — scale_color

See pal_gsea() for details.

scale_color_gsea(palette = c("default"), alpha = 1, reverse = FALSE, ...)

scale_colour_gsea(palette = c("default"), alpha = 1, reverse = FALSE, ...)

scale_fill_gsea(palette = c("default"), alpha = 1, reverse = FALSE, ...)

Arguments

palette: Palette type. Currently there is one available option: "default" (continuous palette with 12 base colors).
alpha: Transparency level, a real number in (0, 1]. See alpha in grDevices::rgb() for details.
reverse: Logical. Should the order of the colors be reversed?
...: Additional parameters for ggplot2::discrete_scale().

Examples

data("mtcars")
cor <- cor(mtcars)
cor_melt <- data.frame(
  Var1 = rep(seq_len(nrow(cor)), times = ncol(cor)),
  Var2 = rep(seq_len(ncol(cor)), each = nrow(cor)),
  value = as.vector(cor)
)

ggplot(
  cor_melt,
  aes(x = Var1, y = Var2, fill = value)
) +
  geom_tile(colour = "black", size = 0.3) +
