Pat uses R to show how to recreate a stacked bar plot positioned next to a bar plot that was posted by the Pew Research Center describing people's sense of how different groups will fare under the Trump Administration. To pull this off he uses the ggplot2, showtext, and ggtext packages. The functions he uses from these packages include abs, aes, annotate, as.character, case_when, coord_cartesian, element_blank, element_markdown, element_text, factor, font_add_google, function, geom_col, geom_crossbar, geom_text, geom_text, geom_vline, ggplot, ggsave, if_else, labs, library, margin, max, mutate, mutate, mutate, mutate, pivot_longer, rev, scale_fill_manual, select, select, showtext_auto, showtext_opts, theme, and tribble.
