BrewerClusterCol {Heatplus} | R Documentation |
This function returns a color vector based on one of the qualitative
paletters supported by RColorBrewer
. This allows visually distinct
coloring of clusters and ensures sure that adjacent clusters have different
colors.

This is just a wrapper for brewer.pal
that checks that the
specified palette is qualitative, and allows for an arbitrary number of
colors: for less than three colors, it just returns the first and second
colors of the palette; for more than maxcolors
colors, it recycles
the basic palette as often as required. This is ok, because the main point
is to have different colors for neighboring clusters.
A character vector of length n
of hexadecimal color codes.
## A Color Wheel: default palette with maximum number of colors pie(rep(1,9), col=BrewerClusterCol(9)) ## Double the number of colors pie(rep(1,18), col=BrewerClusterCol(18)) ## Only two clusters/colors pie(rep(1,2), col=BrewerClusterCol(2)) ## Different qualitative palette: stronger colors pie(rep(1,12), col=BrewerClusterCol(12, "Paired"))
