将向量列表附加到向量列表中

Question

Let x be a list of vectors:

 a <-list( c(1,2,3),   c(4,5,6), c(7,8) ,c(9) )
 b <-list(c(11,22,33),c(44,55,66), c(77,88) ,c(99) )
 x <- list(a=a,b=b)

My desired output is the following:

>foo(x)

 list(c(1,2,3,11,22,33),c(4,5,6,44,55,66),c(7,8,77,88),c(9,99)

Summary of Answers by the Akrun and gfgm

1. Map(c, a, b)
2. do.call(Map, c(f = "c", unname(x)))
3. mapply(function(i, j){c(i,j)}, a, b)

Answer 1

This is a good use case for mapply()

a <-list( c(1,2,3),   c(4,5,6), c(7,8) ,c(9) )
b <-list(c(11,22,33),c(44,55,66), c(77,88) ,c(99) )

mapply(function(i, j){c(i,j)}, a, b)
