You will also learn how to use these palettes in ggplot2 and in R base plots.

These. pal().

The color scales defined in the RColorBrewer and in other packages, such as viridis, have a fixed number of colors.

For continuous scale, we cannot use the RColorBrewer package directly since it only has discrete palettes.

The scales scale_colour_binned() and scale_fill_binned() are equivalent scale functions that assign discrete color bins to the continuous values instead of using a continuous color spectrum. The brewer scales provide sequential, diverging and qualitative colour schemes from ColorBrewer. I wrote a function and on the same chart I superimpose from 1 to 4 lines.

The scales scale_colour_continuous() and scale_fill_continuous() are the default colour scales ggplot2 uses when continuous data values are mapped onto the colour or fill aesthetics, respectively.
