在ggplot2上为不同长度的向量创建小提琴图？

install.packages("ggplot2")

library(ggplot2)

vec1 <- rnorm(10)
vec2 <- rnorm(20)
vec3 <- rnorm(30)

df <- data.frame(
  length = c(rep("vec1", length(vec1)), rep("vec2", length(vec2)), rep("vec3", length(vec3))),
  value = c(vec1, vec2, vec3)
)

ggplot(df, aes(x = length, y = value)) +
  geom_violin()

ggplot(df, aes(x = length, y = value, fill = length)) +
  geom_violin() +
  scale_fill_manual(values = c("vec1" = "red", "vec2" = "blue", "vec3" = "green")) +
  labs(x = "Vector Length", y = "Value", title = "Violin Plot of Vectors")
