Get colors by bin.

Source: R/plotting.R

Get colors for elements according to their bin. Colors are assigned to bins forming a gradient from col1 to col2 in the order of levels{b}. col0 is assigned to the neutral bin (attribute "") if available.

getColsByBin(
  b,
  col1 = c("#003C30", "#01665E", "#35978F", "#80CDC1", "#C7EAE5"),
  col2 = c("#F6E8C3", "#DFC27D", "#BF812D", "#8C510A", "#543005"),
  col0 = "#F5F5F5"
)

Arguments

Value

A character vector with colors for the elements in b.
