如何以指定顺序连接字符串 [英] How to concatenate strings in a specified order

问题描述

尝试通过这篇文章对角地连接字符串如何交替连接3个字符串，但未成功。

Tried to concatenate strings diagonally from this post how to alternatively concatenate 3 strings, but was not successful.

我的输入是：

a<-c("a1","a2","a3")
b<-c("b1","b2","b3")
c<-c("c1","c2","c3")

我的预期输出为

   "a1" "b2" "c3" "a2" "b3" "a3"

如何从中获取以上信息

  c(rbind(a,b,c))  

推荐答案

How about ordering the vector by values derived by the row and columns after setting the lower diagonal to missing

mat <- rbind(a,b,c)

mat[lower.tri(mat)] <- NA
