英文:
expand data from column to multiple rows
问题
这是我试图在R中扩展到多列的数据的一个示例练习
Location <- c(rep("ATL", 3), rep("CLE", 3), rep("BOS", 3))type <- rep(c("sedan", "truck", "coupe"), 3)pro1 <- rep(c("0800 SC", "1500 SC", "0900 SC"), 3)pro2 <- rep(c("0800 SC", "1500 SC", "0900 SC"), 3)pro3 <- rep(c("1000 SC", "1700 SC", "1100 SC"), 3)pro4 <- rep(c("1300 SC", "1100 SC", "2300 SC"), 3)x <- data.frame(Location, type, pro1, pro2, pro3, pro4)
我试图将数据转移到Excel文件的屏幕截图
期望的输出（来自Excel的屏幕截图）:
当前的输出:

This is a practice an example of the data I am trying to expand over multiple columns in R
Location<-c(rep("ATL",3),rep("CLE",3),rep("BOS",3))type<-rep(c("sedan","truck","coupe"),3)pro1<-rep(c("0800 SC","1500 SC","0900 SC"),3)pro2<- rep(c("0800 SC","1500 SC","0900 SC"),3)pro3<-rep(c("1000 SC","1700 SC","1100 SC"),3)pro4<-rep(c("1300 SC","1100 SC","2300 SC"),3)x<-data.frame(Location,type,pro1,pro2,pro3,pro4)
I am trying to transfer the data into the screenshot of the excel file

你只需要使用 tidyr::pivot_longer()。
library(tidyr)Location<-c(rep("ATL",3),rep("CLE",3),rep("BOS",3))type<-rep(c("sedan","truck","coupe"),3)pro1<-rep(c("0800 SC","1500 SC","0900 SC"),3)pro2<- rep(c("0800 SC","1500 SC","0900 SC"),3)pro3<-rep(c("1000 SC","1700 SC","1100 SC"),3)pro4<-rep(c("1300 SC","1100 SC","2300 SC"),3)x<-data.frame(Location,type,pro1,pro2,pro3,pro4)x |> pivot_longer(starts_with("pro"), names_to = "pro", values_to = "time")#> # A tibble: 36 × 4#> Location type pro time#> <chr> <chr> <chr> <chr>#> 1 ATL sedan pro1 0800 SC#> 2 ATL sedan pro2 0800 SC#> 3 ATL sedan pro3 1000 SC#> 4 ATL sedan pro4 1300 SC#> 5 ATL truck pro1 1500 SC#> 6 ATL truck pro2 1500 SC#> 7 ATL truck pro3 1700 SC#> 8 ATL truck pro4 1100 SC#> 9 ATL coupe pro1 0900 SC#> 10 ATL coupe pro2 0900 SC#> # ℹ 26 more rows
