如何在 R 中将更宽的 data.frame 重塑为更长的 data.frame? [英] How to reshape a wider data.frame to longer data.frame in R?

问题描述

我在玩 pivot_longer 和 pivot_wider 但可能遗漏了一些东西.我有一个 data.frame 像 D_Wider 并且想把它转换成类似 D_longer 的东西.有什么办法吗?

I was playing with pivot_longer and pivot_wider but probably am missing something. I have a data.frame like D_Wider and would like to convert it to something like D_longer. any way forward?

library(tidyverse)
D_Wider <- data.frame(A = 15, S = 10, D = 25, Z = 16)

期望输出

D_Longer <- data.frame(Stations = c("A","S","D","Z"), Value = c(15,10,25,16))

推荐答案

最简单的是 stack from base R

Easiest would be stack from base R

stack(D_Wider)[2:1]

---

或者使用pivot_longer

library(tidyr)
pivot_longer(D_Wider, cols = everything(), 
     names_to = 'Stations', values_to = 'Value')
