regex - 在R中按单词拆分字符串

Question

我想用两个词分割一个字符串：

s <- "PCB153 treated HepG2 cells at T18"
strsplit(s, split = <treated><at>)

我应该写什么而不是<>？

我会得到：

"PCB153" "HepG2 cells" "T18"

您必须将其作为字符串输入。拆分处理：

s <- "PCB153 treated HepG2 cells at T18"
s2 <- strsplit(s,split="treated")
unlist(s2)

拆分处理和在：

unlist(strsplit(unlist(s2),split="at"))
