R语言画样本不均衡组的箱线图

# 导入 ggplot2 包
library(ggplot2)# 示例数据框，包含数值数据和分组信息
data <- data.frame(Group = c(rep("Group A",10), rep("Group B",15),rep("Group C",20)),Value = c(rnorm(10, mean = 10, sd = 2),rnorm(15, mean = 15, sd = 2),rnorm(20, mean = 20, sd = 2))
)# 使用 ggplot2 绘制箱线图，同时显示每个数据点
ggplot(data, aes(x = Group, y = Value, fill = Group)) +geom_boxplot(outlier.shape = NA) +  # 不显示异常值geom_jitter(width = 0.2, alpha = 0.7) +  # 绘制数据点，width控制点的分布宽度，alpha控制透明度labs(title = "Box Plot with Unequal Group Sizes and Data Points",x = "Group",y = "Value") +theme_minimal()  # 使用简洁的主题
