colsplit不守所有列在數據幀

Question

我已經採取一列，並使用colsplit它一分爲二。我的數據框由分割的兩列組成。我丟失了數據框中的所有其他列。如何拆分一列並將新的拆分列添加到當前數據框？

數據幀之前拆分

   X0  X1 Period 
      <chr> <dbl> <int> 
1 1973 January 108.289  1 
2 1973 February 97.698  2 
3 1973 March  97.366  3 
4 1973 April  93.084  4 
5 1973 May  94.346  5 
6 1973 June  97.757  6 

應用colsplit

> A <- colsplit(subemission$X0, " ", c("Year", "Month")) 
> head(A) 
    Year  Month 
1 1973 January 
2 1973 February 
3 1973 March  
4 1973 April  
5 1973 May  
6 1973 June  

Answer 1

我們可以使用separate從tidyr與remove=FALSE

library(tidyverse) 
separate(subemission, XO, into = c("Year", "Month"), remove = FALSE)

或用cSplit

cSplit(subemission, "XO", " ", drop = FALSE) 

---

或用read.table

cbind(subemission, read.table(text= subemission$XO, 
    header=FALSE, col.names = c("Year", "Month"), stringsAsFactors=FALSE))
