Source: R/graphics_helpers.R
ft_discretize_colorscale.Rd

When one is using a continuous colorscale to visualize data (say log-fold-changes or correlations), it may be useful to create discrete colors from a usually continuous color scale.

Usage

ft_discretize_colorscale(
  color_scale = NULL,
  discrete_locs = c(25, 75),
  show_colors = TRUE
)

Arguments

color_scale

the color scale to take colors from

discrete_locs

where to take them from

show_colors

create a plot showing the continuous and discrete colors

discrete_n

how many colors to take

Value

vector of colors
