Separate a collapsed column into multiple rows

separate_rows() has been superseded in favour of separate_longer_delim() because it has a more consistent API with other separate functions. Superseded functions will not go away, but will only receive critical bug fixes.

If a variable contains observations with multiple delimited values, separate_rows() separates the values and places each one in its own row.

Usage

separate_rows(data, ..., sep = "[^[:alnum:].]+", convert = FALSE)

Arguments

data

A data frame.

...

<tidy-select> Columns to separate across multiple rows

sep

Separator delimiting collapsed values.

convert

If TRUE will automatically run type.convert() on the key column. This is useful if the column types are actually numeric, integer, or logical.

Examples

df <- tibble(
  x = 1:3,
  y = c("a", "d,e,f", "g,h"),
  z = c("1", "2,3,4", "5,6")
)
separate_rows(df, y, z, convert = TRUE)
#> # A tibble: 6 × 3
#>       x y         z
#>   <int> <chr> <int>
#> 1     1 a         1
#> 2     2 d         2
#> 3     2 e         3
#> 4     2 f         4
#> 5     3 g         5
#> 6     3 h         6

# Now recommended
df %>%
  separate_longer_delim(c(y, z), delim = ",")
#> # A tibble: 6 × 3
#>       x y     z    
#>   <int> <chr> <chr>
#> 1     1 a     1    
#> 2     2 d     2    
#> 3     2 e     3    
#> 4     2 f     4    
#> 5     3 g     5    
#> 6     3 h     6
