r - 在 R 中拆分 CamelCase

Question

有没有办法在 R 中拆分驼峰式字符串？

我尝试过:

string.to.split = "thisIsSomeCamelCase"
unlist(strsplit(string.to.split, split="[A-Z]") )
# [1] "this" "s"    "ome"  "amel" "ase" 

Answer 1

string.to.split = "thisIsSomeCamelCase"
gsub("([A-Z])", " \\1", string.to.split)
# [1] "this Is Some Camel Case"

strsplit(gsub("([A-Z])", " \\1", string.to.split), " ")
# [[1]]
# [1] "this"  "Is"    "Some"  "Camel" "Case" 

看看 Ramnath 和我的，我可以说我最初的印象是，这是一个未具体说明的问题得到了支持。

并为 Tommy 和 Ramanth 的指出点赞 [:upper:]

strsplit(gsub("([[:upper:]])", " \\1", string.to.split), " ")
# [[1]]
# [1] "this"  "Is"    "Some"  "Camel" "Case"
