This function gets or sets the color palette of a sequence object, that is, the list of colors used to represent the states.
a state sequence object as defined by the
a vector containing the colors, of length equal to the number of states in the alphabet. The colors can be passed as character strings representing color names such as returned by the
In the plot functions provided for visualizing sequence objects, a different color is associated to each state of the alphabet. The color palette is defined when creating the sequence object, either automatically using the
brewer.pal function of the
RColorBrewer package or by specifying a user defined color vector. The
cpal function can be used to get or set the color palette of a previously defined sequence object.
cpal(seqdata)' a vector containing the colors.
cpal(seqdata) <-' the updated sequence object.
