Row-wise tibble creation

Create tibbles using an easier to read row-by-row layout. This is useful for small tables of data where readability is important. Please see tibble-package for a general introduction.

Usage

tribble(...)

Arguments

...

<dynamic-dots> Arguments specifying the structure of a tibble. Variable names should be formulas, and may only appear before the data. These arguments are processed with rlang::list2() and support unquote via rlang::!! and unquote-splice via rlang::!!!.

Value

A tibble.

See rlang::quasiquotation for more details on tidy dots semantics, i.e. exactly how the ... argument is processed.

Examples

tribble(
  ~colA, ~colB,
  "a",   1,
  "b",   2,
  "c",   3
)
#> # A tibble: 3 × 2
#>   colA   colB
#>   <chr> <dbl>
#> 1 a         1
#> 2 b         2
#> 3 c         3

# tribble will create a list column if the value in any cell is
# not a scalar
tribble(
  ~x,  ~y,
  "a", 1:3,
  "b", 4:6
)
#> # A tibble: 2 × 2
#>   x     y        
#>   <chr> <list>   
#> 1 a     <int [3]>
#> 2 b     <int [3]>

# Use dplyr::mutate(dplyr::across(...)) to assign an explicit type
tribble(
  ~a, ~b, ~c,
  1, "2000-01-01", "1.5"
) %>%
  dplyr::mutate(
    dplyr::across(a, as.integer),
    dplyr::across(b, as.Date)
  )
#> # A tibble: 1 × 3
#>       a b          c    
#>   <int> <date>     <chr>
#> 1     1 2000-01-01 1.5
