尝试仅在 R 中的箱线图轴上显示两个十年

Question

Hi!

This is how my plot looks at the moment... Want to try and only display decades 1980 and 2010 in my box plots. This is how my code looks now:

 gender_race_income <- ggplot(data = gender_pay_gap, aes(x = factor(decade), y = income, colour 
                                                    = sex)) +
   geom_boxplot() +
   coord_flip() +
   facet_grid(rows = vars(race)) +
   scale_y_log10() +
   theme_bw() +
   scale_color_brewer(palette = "Set2")

Thank you:)

welcome to Stack Overflow. You can subset your data using filter() from dplyr and then pass this onto the ggplot using the %>% pipe.

gender_pay_gap %>%
  dplyr::filter(decade == 1980 | decade == 2010) %>%
  ggplot(aes(x = factor(decade), y = income, colour = sex)) +
  geom_boxplot() +
  coord_flip() +
  facet_grid(rows = vars(race)) +
  scale_y_log10() +
  theme_bw() +
  scale_color_brewer(palette = "Set2")
