r - 将R中的单词与数字分开

Question

如何在单词和数字之间创建空格？我一直在搜索 SO，但没有找到 R 的结果。

我有这样的数据框:

1 This is the case34
2 To to that case23/234
3 Only Monday223.23

期望的输出:

1 "This is the","case 34"
2 "To to that","case 23/234"
3 "Only","Monday 223.23"

如此将数字与单词分开，如何处理？

Answer 1

尝试像这样使用 read.table 和 sub:

# data in reproducible form
DF <- data.frame(s=c("This is the case34", "To to that case23/234", "Only Monday223.23"))

read.table(text = sub("(.*\\S) ([[:alpha:]]+)(\\d.+)$", "\\1,\\2 \\3", DF$s), sep = ",")

它给出了这个数据框:

           V1            V2
1 This is the       case 34
2  To to that   case 23/234
3        Only Monday 223.23
