Tidying “Benchmark” columns

 原文  2019-02-18 18:05:04  3   1    r/ tidyverse

Question

I have a data frame that is mostly tidy but 2 columns contain benchmarks rather than incorporating the benchmarks as observations. How do I tidy this so both "Facility_score" and "TTP" col_names are added as observations under "Facility_label" for each unique FYQ and Metric combination?

Input data: 

library(zoo)

dd <- structure(list(Facility_label = structure(c(1L, 1L, 1L, 1L, 2L, 
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 
3L, 3L, 3L, 4L, 4L, 4L, 4L, 4L, 4L), .Label = c("A", "B", "C", 
"D", "Nashville"), class = "factor"), FYQ = structure(c(2017.75, 
2018, 2018.25, 2018.5, 2017.75, 2018, 2018.25, 2018.5, 2018.75,

We can do it with tidyr::gather and some dplyr::mutate manipulation: 

library(tidyverse)

dd %>%
  mutate(ID = row_number()) %>%
  gather(var, Facility_score, Facility_score:TTP_score) %>%
  group_by(FYQ, Metric,
           temp_ID = case_when(var == "Facility mean" ~ 1, 
                               var == "TTP_score" ~ 2, 
                               TRUE ~ 0)) %>%
  slice(if(any(temp_ID == 0)) row_number() else 1) %>%
  mutate(Facility_label = if_else(var == "Facility_score", as.character(Facility_label), var)) %>%
  ungroup() %>%
  arrange(ID, temp_ID) %>% 
  select(ID, everything(), -var, -temp_ID)

Note that I have added the ID column to indicate the original row number. This makes it less confusing when all the scores in the same row are combined.

Notes:

  1. gather reshapes the table from wide to long format treating the entries of Facility_score , Facility mean and TTP_score as the new Facility_score 's. A variable var is created to temporarily store the value labels.

  2. We then group_by FYQ , Metric , and a temporary ID variable ( temp_ID ) created by setting Facility mean to 1 , TTP_score to 2 , and everything else in var to 0 .

  3. Based on temp_ID , we use slice to grab all rows if it's 0 , and only the first row otherwise. This effectively returns all rows corresponding to Facility_score , but only one of Facility mean and TTP_score in each FYQ + Metric combination.

  4. Next, we replace Facility_label with the corresponding labels in var .

  5. Finally, ungroup , arrange by ID and temp_ID , and rearrange the column order while deleting var and temp_ID ( everything is useful when we want to bring a variable(s) in front while keeping other variables untouched).

Output:
