加载内置数据集
data(mtcars)
绘制散点图，显示马力和每加仑英里数的关系
正确写法：括号要包住所有内容
plot(
x = mtcars$hp,
y = mtcars$mpg,
col = "blue",
pch = 19,
main = "必杀技测试成功！"
)
添加红线
abline(lm(mtcars$mpg ~ mtcars$hp), col = "red")
添加线性回归线
abline(lm(mtcars$mpg ~ mtcars$hp), col = "red")
使用ctrl+enter运行这个代码时候
r$> plot()
Error in plot.default() : argument "x" is missing, with no default
r$> x = mtcars$hp,
