如何在R中的表上的边距处增加比例总数？

2024-02-24 06:20:03 496

表格中的总计比例有助于我们了解总计中每一行和每一列的贡献。因此，如果我们想在边距处找到比例总和，如果我们有比例表，则可以使用addmargins函数；如果没有该表，则首先需要创建它，然后再使用addmargins函数。例如，如果我们有一个称为prop的比例表，则命令将为addmargins(prop)。

例1

考虑下表的比例-

> x1<-rpois(5,2)
> x2<-rpois(5,2)
> x3<-rpois(5,2)
> x4<-rpois(5,2)
> x5<-rpois(5,2)
> x6<-rpois(5,2)
> x7<-rpois(5,2)
> x8<-rpois(5,2)
> table1<-prop.table(rbind(x1,x2,x3,x4,x5,x6,x7,x8))
> table1

输出结果

         [,1]       [,2]       [,3]       [,4]       [,5]
x1 0.07692308 0.01538462 0.01538462 0.00000000 0.06153846
