Details

The function is useful to build named RGB color values from factors. brewer.pal.factor return a color-HTML-string vector as the same length of the input factor vector, which is named by the input factor as well. brewer.pal.factorLevels returns a color vector of the length of the factor level, and the colors are named by the levels. See examples below.

From version 1.1-16, the color palette is automatically reduced/expanded when the levels of input factors underlies or exceeds the minimum and maximum colors. See example below.

Examples

# \donttest{
myFac <- factor(c("HSV", "BVB", "FCB", "HSV", "BVB", "HSV"))
brewer.pal.factor(myFac, name="Set1")

myLongFac <- factor(paste("Sample", 1:20))
brewer.pal.factor(myLongFac, name="Set1")

myShortFac <- factor(paste("Sample", 1:2))
brewer.pal.factor(myShortFac, name="Set1")
# }
