将 data.frame 的列拆分为更多列

Splitting column of a data.frame into more columns

我想将 Test data.frameOut 列拆分为基于空白分隔的列 space .这是我的 MWE。我尝试了 tidyr 包中的 separate 函数和 base R 中的 strsplit 函数,但无法找出问题所在。

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

尝试

Test %>% separate(Out, c("A", "B", "C", "D"),  sep = "\s+")

允许多个空格 (\s+)。
