图R中的X轴子标签

Question

我有下面的ggplot代码来渲染下面的框图显示。

ggplot(comparisonData, aes(Group,score)) + 
  geom_boxplot(notch = TRUE, varwidth = TRUE, aes(colour = Group)) +
  geom_jitter(width = 0.2, aes(colour = Group)) + 
  theme(legend.position = "none") + 
  labs(title="User Engagement Score", x="Condition", y="Score (max 140)")

在这个图中，我希望将x轴上的组1和2重命名为“隐形”和“非隐形”，但我找不到这样做的方法。可以不更改数据中的组名吗？

Answer 1

你可以通过刻度来改变标签，例如

library(tidyverse)
library(palmerpenguins)

penguins %>% 
  na.omit() %>%
  mutate(species = factor(ifelse(species == "Adelie", 1, 2))) %>% 
  ggplot(aes(x = species, y = bill_length_mm)) +
  geom_boxplot(aes(colour = species), notch = TRUE, varwidth = TRUE) +
  geom_jitter(width = 0.2, aes(colour = species)) + 
  theme(legend.position = "none") + 
  labs(title="User Engagement Score", x="Condition", y="Score (max 140)") +
  scale_x_discrete(label = c("Stealth", "Non-stealth"))
