R pivot_更长，将第一列行名转换为列名

使用这些数据：

第一列包含行： 自杀人数 男性的 女的 全部的 每100000人的年龄标准化死亡率 男性的 女的 总数

但是，我需要这些作为列标题。这是通过pivot_实现的吗

谢谢

这是一个非常难看的数据文件，但希望它能满足您的需要：

library(dplyr)
library(tidyr)

# After downloading the file in your project folder
dat <- readxl::read_excel("suicide-2015-tables.xlsx", skip = 2)

dat %>% 
  select(variables = ...1, `2006`:`2015`) %>% # Remove unneeded/blank columns
  mutate(headers = if_else(is.na(`2006`), variables, NA_character_)) %>% # Create a headers variable
  fill(headers, .direction = "down") %>% # Fill the headers down
  pivot_longer(`2006`:`2015`, names_to = "year", values_to = "counts") %>% # Reshape data from wide to long
  drop_na() %>% 
  unite("headers_vars", headers, variables, sep = " - ") %>% # Create a new variable that combines the headers and the subgroup breakdown
  pivot_wider(names_from = headers_vars, values_from = counts) # Reshape back from long to wide
