r - 在散点图上添加 PIL 逊相关系数

Question

这个问题已经有答案了:

How to plot additional statistics in boxplot for each group? (1 个回答)

已关闭 9 年前。

我制作了一个散点图，需要在图表中的某处包含年龄和高度的 PIL 逊相关系数。这是我已经完成的部分工作。

plot(survey$Age, survey$Height,main="A scatter plot of Age against Height",xlab="Age(years)",ylab="Height(cm)")

我使用的数据集在这里。调查

Answer 1

我通常使用legend或text向绘图添加信息。例如:

legend(x='bottomright', legend='Cor = 0.34')

在你的情况下，它会更像这样:

legend(x='bottomright', legend=paste('Cor =',round(cor(survey$Age, survey$Height),2)))
