我只想将文本添加到一列。
我尝试了以下（这里作为示例）：
employee <- c('John Doe','Peter Gynn','Jolie Hope')
addMe <- c('test1','test2','test3')
salary <- c(21000, 23400, 26800)
dat <- data.frame(employee, salary, addMe)
dat[] <- lapply(dat$addMe, function(x) paste(' Please delete this col!', x))
但是，我的结果框架如下所示：
employee salary addMe
1 Please delete this col! John Doe Please delete this col! 21000 Please delete this col! test1
2 Please delete this col! Peter Gynn Please delete this col! 23400 Please delete this col! test2
3 Please delete this col! Jolie Hope Please delete this col! 26800 Please delete this col! test3
但是，我希望得到以下结果：
employee salary addMe
1 John Doe 21000 Please delete this col! test1
2 Peter Gynn 23400 Please delete this col! test2
3 Jolie Hope 26800 Please delete this col! test3
有什么建议我做错了吗？
感谢您的答复！
最佳答案
赶紧跑
dat$addMe <- paste0("Please delete this col! ", dat$addMe)
代替你的麻线。
