Vectorized switch() — case_match • tidytable

Allows the user to succinctly create a new vector based off conditions of a single vector.

case_match(.x, ..., .default = NA, .ptype = NULL)

Arguments

.x: A vector
...: A sequence of two-sided formulas. The left hand side gives the old values, the right hand side gives the new value.
.default: The default value if all conditions evaluate to FALSE.
.ptype: Optional ptype to specify the output type.

Examples

df <- tidytable(x = c("a", "b", "c", "d"))

df %>%
  mutate(
    case_x = case_match(x,
                        c("a", "b") ~ "new_1",
                        "c" ~ "new_2",
                        .default = x)
  )
#> # A tidytable: 4 × 2
#>   x     case_x
#>   <chr> <chr> 
#> 1 a     new_1 
#> 2 b     new_1 
#> 3 c     new_2 
#> 4 d     d
