### 123.txt
comment: "it is nice and great"
comment: "it is nice"
comment: "it is great:"
### main.r
test=readLines("C:\\Users\\Administrator\\Desktop\\123.txt")
sapply(test, function(v) {
tmp = strsplit(v, " ")[[1]]
c(tmp[1], paste(tmp[2:length(tmp)], collapse = " "))})
Result:
[1,] "comment:" "comment:"
[2,] "\"it is nice and great\"" "\"it is nice\""
[1,] "comment:"
[2,] "\"it is great:\""
Note: 如果不要什麼，就用gsub取代成""就好
※ 引述《ryansun (sun)》之銘言：
: 請問我有一段話 形式大概如這樣
: comment: "it is nice and great"
: 想把comment與"it is nice and great"分別存在兩個變數裡
: 我試著用下列code做
: test=readLines("123.txt")
: strsplit(test, " ")
: 但結果是只要遇到空白就會切開
: [1] "comment:" "\"it" "is" "nice" "and" "great\""
: 有什麼方法是讀到第一個空白處才會分割 後面就不會繼續切下去
: 謝謝指教
