从数据集中的所有变量命名的特殊字符/符号(Rename special character / sy

我试图改变所有数据集，以取代特殊符号和字符， 但我想用dplyr来执行 ，我没有找到答案。 当我说“特殊”，我的意思是在国外的语言，如葡萄牙语中的典型符号。

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))

         quectão18

为什么我的问题：

论坛成员，帮我用dplyr收集变量和总结其成果 ，但它不是在与特殊符号变量工作：

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，并要检查，要解决这个问题，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(.))))

其次，使用看门包

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