对于R到data.frame的循环

Question

我有以下data.frame

Name<-c("Jack","Jerry","Emma","Andy","Jayde","Lynn","Liam")
Education<-c("Master","Master","Master","Bach","Bach","PhD","PhD")
Salary<-c(20000,20000,20000,30000,10000,70000,70000)
People<-data.frame(Name,Education,Salary)

我现在必须使用for循环（愚蠢，我知道）循环框架，找到＆＃34;教育＆＃34;等级，并增加工资增长。

怎么办呢？

Answer 1

即使按照评论中提到的那样做得更好，你也可以用丑陋的方式做到：

for (i in 1:nrow(People)) {
  if (People$Education[i] == "Bach") {
    People$Salary[i] <- People$Salary[i]+1000
  } else if (People$Education[i] == "Master") {
    People$Salary[i] <- People$Salary[i]+2000
  } else {
    People$Salary[i] <- People$Salary[i]+3000
  }
}
