重命名数据集中所有变量的特殊字符/符号

Question

我正在尝试更改所有数据集以替换特殊符号和字符，但我想使用 dplyr 来执行该操作，但我没有找到答案。当我说 "special" 时，我指的是外语中常见的符号，例如葡萄牙语。

ds <- data.frame(group=c("american", "canadian"), 
                 queçtão.1=rnorm(n=50,mean=100,sd=15),
                 queçtão.2=rnorm(n=50, mean=1500, sd=300),
                 queçtão.18=rnorm(n=50, mean=5, sd=2))

类似于

         quectao1
         quectao2
         quectão18

为什么我的问题：

一位论坛成员帮助我，但它不适用于带有特殊符号的变量：

set.see(123)
ds <- data.frame(group=c("american", "canadian"), 
                 queçtão.1=rnorm(n=50,mean=100,sd=15),
                 queçtão.2=rnorm(n=50, mean=1500, sd=300),
                 queçtão.18=rnorm(n=50, mean=5, sd=2))

ds %>% 
  group_by(group) %>% 
  summarise_at(vars(queçtão.1,queçtão.2,queçtão.18),funs(mean, sd)) %>% 
  gather(key, val, queçtão.1_mean:queçtão.18_sd) %>% 
  separate(key, into = c('key1', 'key2')) %>% 
  unite(group, group, key2) %>%
  spread(group, val)

Error: Duplicate identifiers for rows (1, 7), (5, 11), (3, 9), (2, 8), (6, 12), (4, 10)
In addition: Warning message:
Expected 2 pieces. Additional pieces discarded in 12 rows [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12].

Answer 1

如果你在这里想查看这个问题的答案，我有两个选择。

首先，使用dplyr：

ds <- ds %>% setNames(tolower(gsub("\.","",names(.)))) %>% 
   setNames(tolower(gsub("\_","",names(.)))) %>% 
   setNames(tolower(gsub("ç","c",names(.)))) %>% 
   setNames(tolower(gsub("ã","a",names(.))))

二、使用看门人包

library(janitor)
ds <- ds %>% clean_names()

Rename special character / symbols from all variables in the dataset

r

special-characters

dplyr
