如何使用具有句点3答案的strsplit函数

I have:

我有：

"word1.word2"

and I want:

而且我要：

"word1" "word2"

I know I have to use strsplit with perl=TRUE, but I can't find the regular expression for a period (to feed to the split argument).

我知道我必须使用strsplit和perl = TRUE，但我找不到一段时间的正则表达式（以反馈split参数）。

There are several ways to do this, both with base R and with the common string processing packages (like "stringr" and "stringi").

有几种方法可以做到这一点，包括基本R和常见的字符串处理包（如“stringr”和“stringi”）。

Here are a few in base R:

以下是基数R中的一些：

str1 <- "word1.word2"

strsplit(str1, ".", fixed = TRUE)  ## Add fixed = TRUE
strsplit(str1, "[.]")              ## Make use of character classes
strsplit(str1, "\\.")              ## Escape special characters

Try this

尝试这个

library(stringr)
a <- "word1.word2"
str_split(a, "\\.")
