分割字符串

Question

我想用兩個詞來分割字符串：

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

我應該寫的，而不是<>什麼？

我會得到：

"PCB153" "HepG2 cells" "T18" 

Answer 1

strsplit(s, split="treated|at") 
#[[1]] 
#[1] "PCB153 "  " HepG2 cells " " T18" 

Answer 2

您必須輸入它作爲一個字符串。拆就處理：

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

拆就處理，並於：

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