In addition to the color palette in R that can be represented as either color literals or hexadecimal values, numeric values can also be used to add colorization to a plot. Numeric values ranging from 1 to 8 provide 8 basic colors that can be deployed. The rcolorconst function returns both a Named Vector and a color palette plot that connects these numeric values with their corresponding color.
