r - 非典型数据格式从长转换为宽

Question

我的数据:

    # A tibble: 6 x 4
  X__1            X__6                                                     X__7     X__8        
  <chr>           <chr>                                                    <chr>    <chr>       
1 Emp #:          xxyy                                                    Departm~ Corporate S~
2 Reason of Resi~ I think below are areas of improvement within my team C~ NA       NA          
3 Emp #:          xyyy                                                    Departm~ Corporate S~
4 Reason of Resi~ better oppurtunity                                       NA       NA          

我想把数据改成下面的格式

Emp #     Reason                                                 Department
10282     I think below are areas of improvement within my team  Corporate
10308     better oppurtunity                                     Corporate

复现数据

structure(list(X__1 = c("Emp #:", "Reason of Resignation:", "Emp #:", 
"Reason of Resignation:", "Emp #:", "Reason of Resignation:", 
"Emp #:", "Reason of Resignation:", "Emp #:", "Reason of Resignation:"
), X__6 = c("10282", "I think below are areas of improvement within my team CS / SME or my be cross the organization on my level (L1-L2). Lack of career growth specially in my department i.e. CS HOD/RSM/TLs/KAMs are on same position from last 5 years. Many people are here on same position from last 10-12 years. lack in focus on low level staff (L1 / L2) in terms of capacity building and career growth i.e. not a single training for my team on it.

"10308", "better oppurtunity", "11230", "Moving on another organization for career persuade", 
"13370", "Get a new job outside the company.", "14694", "Health Issues"
), X__7 = c("Department:", NA, "Department:", NA, "Department:", 
NA, "Department:", NA, "Department:", NA), X__8 = c("Corporate Solutions", 
NA, "Corporate Solutions", NA, "Region Central A", NA, "Region North", 
NA, "Finance Operations", NA)), row.names = c(NA, -10L), class = c("tbl_df", 
"tbl", "data.frame"))

更详细一些。

X__1 中的

Emp# 将出现在第一列标题中，该标题的值来自 X__6 等等。

Answer 1

我添加了一个名为 rid 的新列，该列对行进行分组，然后过滤出所需的列，然后 left_join() 通过它们的 rid< 将它们重新组合在一起.

library(dplyr)

df <- mutate(df, rid = lapply(1:(nrow(df)/2), function(x) rep(x, 2)) %>% unlist())

left_join(
  df %>%
    filter(X__1 == "Emp #:") %>%
    select(rid, X__6) %>%
    rename("Emp #" = "X__6"),
  df %>%
    filter(X__1 == "Reason of Resignation:") %>%
    select(rid, X__6) %>%
    rename("Reason" = "X__6"),
  by = "rid") %>%
  left_join(df %>%
              filter(X__7 == "Department:") %>%
              select(rid, X__8) %>%
              rename("Department" = "X__8"),
            by = "rid") %>%
  select(-rid)

#  `Emp #` Reason                                                    Department     
#   <chr>   <chr>                                                     <chr>
