Identify inconsistent column names across data frames

This function checks for consistency in column names across a list of data frames. It returns the symmetric difference between the shared columns (those present in all data frames) and the union of all column names (those present in any data frame).

Usage

find_inconsistent_colnames(data_list)

Arguments

data_list

A list of data frames to check.

Value

A character vector of column names that are not shared across all data frames. These are the inconsistent or unique column names that appear in only some of the data frames.

Examples

df1 <- data.frame(a = 1, b = 2)
df2 <- data.frame(a = 3, c = 4)
df_list <- list(df1, df2)
find_inconsistent_colnames(df_list)
#> # A tibble: 2 × 1
#>   colnames
#>   <chr>   
#> 1 b       
#> 2 c       
# Returns: "b" "c"
