r - 我如何整理这个爸爸妈妈数据集？

Question

谁能帮我整理 R 中的这个数据集？

这是原始形式:

## # A tibble: 3 x 5
    ##   famid named  incd namem  incm
    ##   <dbl> <chr> <dbl> <chr> <dbl>
    ## 1     1 Bill  30000 Bess  15000
    ## 2     2 Art   22000 Amy   18000
    ## 3     3 Paul  25000 Pat   50000

我正在尝试将其转换为这种形式:

## # A tibble: 6 x 4
    ##   famid parent name    inc
    ##   <dbl> <chr>  <chr> <dbl>
    ## 1     1 d      Bill  30000
    ## 2     1 m      Bess  15000
    ## 3     2 d      Art   22000
    ## 4     2 m      Amy   18000
    ## 5     3 d      Paul  25000
    ## 6     3 m      Pat   50000

谢谢!

我一直在尝试使用pivot_longer，但不断收到来自 R 的错误

Answer 1

library(tibble)
library(dplyr)
library(tidyr)

mydata <- tribble(
~famid, ~named, ~ incd, ~namem,  ~incm,
 1, "Bill",  30000, "Bess",  15000,
 2, "Art",   22000, "Amy",   18000,
 3, "Paul",  25000, "Pat",   50000)

mydata |> 
  rename(name_d = named, inc_d = incd, name_m = namem, inc_m = incm) |> 
  pivot_longer(!famid, names_to = c(".value", "parent"), names_sep = "_")

# A tibble: 6 × 4
  famid parent name    inc
  <dbl> <chr>  <chr> <dbl>
1     1 d      Bill  30000
2     1 m      Bess  15000
3     2 d      Art   22000
4     2 m      Amy   18000
5     3 d      Paul  25000
6     3 m      Pat   50000
