Chapter 8 Rmarkdownsyntax

Generate a graph with ggplot (any graph you like, here are some examples) and try some options to make it colourblind-friendly. Test your figure here (Export your graph to jpeg using the export option in Rstudio (bottom right, above the graph) or ggsave() and upload the file to this website.)

library(ggplot2)
# Using median
mpg %>%
  mutate(class = fct_reorder(class, hwy, .fun='median')) %>%
  ggplot( aes(x=reorder(class, hwy), y=hwy, fill=class)) + 
    geom_boxplot() +
    xlab("class") +
    theme(legend.position="none") +
    xlab("")

# Using number of observation per group
mpg %>%
  mutate(class = fct_reorder(class, hwy, .fun='length' )) %>%
  ggplot( aes(x=class, y=hwy, fill=class)) + 
    geom_boxplot() +
    xlab("class") +
    theme(legend.position="none") +
    xlab("") +
