`RColorBrewer::brewer.pal()` throws an (in this case) unnecessary warning if the output plot requires less than 2 colors. This is an easy fix, and does not change the workings of the code since `RColorBrewer::brewer.pal()` never returns less than three levels anywas: ``` > RColorBrewer::brewer.pal(2, "Set2") [1] "#66C2A5" "#FC8D62" "#8DA0CB" Warning message: In RColorBrewer::brewer.pal(2, "Set2") : minimal value for n is 3, returning requested palette with 3 different levels ```
