[英]Splitting column of a data.frame into more columns
I want to split the Out column of Test data.frame
into columns separating based on blank space. 我想将Test
data.frame
的Out列data.frame
为基于空白分隔的列。 Here is my MWE. 这是我的MWE。 I tried
separate
function from tidyr
package and strsplit
function from base
R
but couldn't figured out the problem. 我试图
separate
功能从tidyr
包和strsplit
功能从base
R
但不能想出的问题。
Test <-
structure(list(Out = structure(1:2, .Label = c("t1* -0.4815861 0.3190424 0.2309631",
"t2* 0.9189246 -0.1998455 0.2499412"), class = "factor")),
.Names = "Out", row.names = c(NA, -2L), class = "data.frame")
library(dplyr)
library(tidyr)
Test %>% separate(Out, c("A", "B", "C", "D"), sep = " ")
Error: Values not split into 4 pieces at 1, 2
strsplit(Test$Out, " ")
Error in strsplit(Test$Out, " ") : non-character argument
try 尝试
Test %>% separate(Out, c("A", "B", "C", "D"), sep = "\\s+")
which allows for multiple spaces ( \\\\s+
). 允许有多个空格(
\\\\s+
)。
