使用ggplot对`R‘中的多个列进行箱图

install.packages("ggplot2")

library(ggplot2)

df <- data.frame(A = c(1, 2, 3, 4, 5),
                 B = c(6, 7, 8, 9, 10),
                 C = c(11, 12, 13, 14, 15))

p <- ggplot(data = df)

p + geom_boxplot(aes(x = "A", y = A)) +
    geom_boxplot(aes(x = "B", y = B)) +
    geom_boxplot(aes(x = "C", y = C))

p + geom_boxplot(aes(x = "A", y = A)) +
    geom_boxplot(aes(x = "B", y = B)) +
    geom_boxplot(aes(x = "C", y = C)) +
    labs(title = "Boxplot of Columns A, B, and C",
         x = "Columns",
         y = "Values")
