Details

Users can customize the plots through ..., which is passed to ggplot2::geom_text() and ggrepel::geom_text_repel(). The colors are specified internally but users can override the settings by appending ggplot2::scale_colour_manual() or ggplot2::scale_colour_brewer(). The legend title can also be modified using ggplot2::labs().
