Question

我有这样一个向量：

a<-c(0.8,1,1.2,3,4,5,6)

每个值都用年份表示，我想将它们分为三个类别（“一年以下”，“一年至五年以上”和“五年以上”）

我的代码如下：

AAA_factor <- cut(x = a, breaks = c(0, 1, 5),labels = c("One year or less","Over one year to five years", "Over five years"))

当我运行这段代码时，它会向我返回此错误：

Error in cut.default(x = a, breaks = c(0, 1, 5), labels = c("One year or less",  : 
  lengths of 'breaks' and 'labels' differ

如何解决此问题？

我还想将子分组添加为a的另一列。

尝试过：

a_group <-data.frame(a,cut(x = a, breaks = c(0, 1, 5),labels = c("One year or less","Over one year to five years", "Over five years"))) 
names(a_group)[2]<-"Time bucket"

有更好的方法吗？

Answer 1

三个端点将仅给出2个区域。而是添加无限大的上限

AAA_factor <- cut(x = a, breaks = c(0, 1, 5, Inf),
    labels = c("One year or less","Over one year to five years", 
    "Over five years"))
AAA_factor
[1] One year or less            One year or less           
[3] Over one year to five years Over one year to five years
[5] Over one year to five years Over one year to five years
[7] Over five years
