问题描述
我需要一些有关列表列表排序的帮助.假设我列出了以下孩子:
I need some help with sorting a list of lists. Suppose I have a list of children given as following:
a <- list(name = "Ann", age = 9)
b <- list(name = "Bobby", age = 17)
c <- list(name = "Alex", age = 6)
my.list <- list(a, b, c)
我想按年龄对他们的名字进行排序，因此请获得以下信息:
I would like to sort their names by their age, so receive the following:
> "Alex" "Ann" "Bobby"
推荐答案
a <- list(name = "Ann", age = 9)
b <- list(name = "Bobby", age = 17)
c <- list(name = "Alex", age = 6)
L <- list(a,b,c)
ages <- sapply(L,"[[","age")
names <- sapply(L,"[[","name")
names[order(ages)]
