简单的字符拆分让我感到困惑

Question

如下所示的拆分使我发疯...需要一些帮助才能发现问题出在哪里

> p5<-Data$poorcoverageusers[5]
> p5
[1] "405874050693761|405874004853834|405874056470063|405874055308702"
> strsplit(p5,"|")
[[1]]
 [1] "4" "0" "5" "8" "7" "4" "0" "5" "0" "6" "9" "3" "7" "6" "1" "|" "4" "0" "5" "8" "7" "4" "0" "0" "4" "8" "5" "3" "8" "3" "4" "|" "4" "0" "5"
[36] "8" "7" "4" "0" "5" "6" "4" "7" "0" "0" "6" "3" "|" "4" "0" "5" "8" "7" "4" "0" "5" "5" "3" "0" "8" "7" "0" "2"

> typeof(Data$poorcoverageusers[5])
[1] "character"

我希望将其用“ |”分隔...因此输出应为405874050693761 405874004853834 405874056470063 405874055308702

我在犯什么错误。

寻求帮助

library(stringr)

s <- "405874050693761|405874004853834|405874056470063|405874055308702"

str_split(s, fixed("|"))                # returns a list of character vectors
# [[1]]
# [1] "405874050693761" "405874004853834" "405874056470063" "405874055308702"

str_split(s, fixed("|"), simplify = T)  # returns a character matrix
#      [,1]              [,2]              [,3]              [,4]             
# [1,] "405874050693761" "405874004853834" "405874056470063" "405874055308702"
