如何在ggplot2中绘制伽玛分布

install.packages("ggplot2")

library(ggplot2)

x <- seq(0, 10, by = 0.1)  # 设置x轴的取值范围和步长
y <- dgamma(x, shape = 2, rate = 1)  # 计算伽玛分布的概率密度函数的值
data <- data.frame(x, y)  # 创建数据框

plot <- ggplot(data, aes(x = x, y = y))

plot <- plot + geom_line()

plot <- plot + labs(title = "Gamma Distribution", x = "X", y = "Density")

print(plot)
