R:将单词从一列中提取到不同的列中 [英] R:Extracting words from one column into different columns

问题描述

我已经弄清楚了两个小时. 假设我有一列包含1-4个单词的列，并用空格隔开:

I've been figuring this out for a couple of hours now. Let's say I have a column with 1-4 words, separated by space:

aba bkak absbs
a2aj akls bios
sad
fasa lgk
.
.
.

我希望这些词放在不同的列中，以便于进一步处理.因此，这些单词放在一列中，如何将它们分开?

I would like those words to be in separate columns, for easier further processing. SO instead those words are in one column, how do I get them to separate columns?

感谢您的帮助.

推荐答案

尝试

library(splitstackshape)
cSplit(df1, 'V1', ' ')

或

library(tidyr)
separate(df1, 'V1', paste0('V', 1:4), sep= ' ', extra='drop')

或使用base R

read.table(text=df1$V1, sep=' ', fill=TRUE)

注意:将列名用作"V1"，将数据集用作"df1"

NOTE: Used the column name as 'V1' and dataset as 'df1'
