scale_colour_discrete.Rd. The default discrete colour scale. Defaults to scale_fill_hue () / scale_fill_brewer () unless type (which defaults to the ggplot2.discrete.fill / ggplot2.discrete.colour options) is.
Changing a palette is a modification of the color (or fill) scale: it involves a change in the mapping from numeric or categorical values to aesthetic attributes. There are two types of scales that use colors : fill scales and color scales. With scale_fill_hue (), the colors are taken from around the color wheel in the HCL (hue-chroma-lightness) …

The functions scale_ colour _manual(), scale_fill_manual(), scale_size_manual(), etc. work on the aesthetics specified in the scale name: colour , fill, size, etc. However, the functions scale_ colour _manual() and scale_fill_manual() also have an optional aesthetics argument that can be used to define both colour and fill aesthetic mappings via a single function call (see examples).
theme(axis.text.x=element_text(size=15, color =black), axis.text.y=element_text(size=15, color =black))+ scale_ fill_discrete (name =House Allegiance, labels=c(Season 1, Season 2, Season 3, Season 4))+ coord_flip(), For discrete == FALSE (the default) all other arguments are as to scale_fill_gradientn or scale_color_gradientn . Otherwise the function will return a discrete_scale with the plot-computed number of colors. See viridis for more information on the color scale.
