还有,有时候我们分类变量的水平比较多,名字比较长,我们可能会将abbrev参数设定为TRUE来缩略显示长度,比如你注意下面的图和上面的在sex水平上的显示区别就是因为我们将abbrev参数设定为了T: 我们还可以很方便地改变列线图的轴标签,只需要将变量打上我们想要的标签,比如将两个变量标签分别设定为“关注”和“Codewar”后...
我想加一个图例,这个时候就需要继续运行legend函数,比如我想圈圈代表‘关注’,三角代表‘Codewar’,我就可以写出如下代码,这儿的“关注”和“Codewar”你都可以换成你想的任何字符哈,这儿仅用它举例: legend(0,800, c("关注","Codewar"), pch=c(19,17), col=c("lightblue","blue")) 图例当然也可以改,...
