我创建了一个包含以下数据的数据框
name <- c("A","B","C","D","E","F","G","H","I","J")
age <- c(22,43,12,17,29,5,51,56,9,44)
sex <- c("M","F","M","M","M","F","F","M","F","F")
rock <- data.frame(name,age,sex,stringsAsFactors = TRUE)
rock
现在我想找出:
如果名称是E到J且性别不等于F则状态为"1F",如果名称为A到D且年龄大于15,则状态为"年轻".其他一切都是"他人"
所以,我正在申请以下代码:
rock$status <- ifelse(rock$name==c("E","F","G","H","I","J")&
rock$sex!="F","1F",
ifelse(rock$name==c("E","F","G","H","I","J")&rock$sex=="F","Fenamle",
ifelse(rock$name==c("A","B","C","D") & rock$age>15,"Young","Others")))
rock
但我得到的输出如下:
name age sex status
1 A 22 M Young
2 B 43 F Young
3 C 12 M Others
4 D 17 M Young
5 E 29 M Others
6 F 5 F Others
7 G 51 F Others
8 H 56 M Others
9 I 9 F Others
10 J …
