使用R中的ggplot创建变量与另一个变量的比例的折线图

install.packages("ggplot2")

library(ggplot2)

df <- data.frame(x = c(1, 2, 3, 4, 5), y = c(10, 20, 30, 40, 50))

p <- ggplot(data = df, aes(x = x, y = y))

p <- p + geom_line()

p <- p + geom_point()

p <- p + scale_y_continuous(labels = scales::percent)

p <- p + labs(title = "Variable Proportion Line Chart", x = "X Variable", y = "Y Variable Proportion")

print(p)
