case_when: Case when

In tidytable: Tidy Interface to 'data.table'

Case when

Description

This function allows you to use multiple if/else statements in one call.

It is called like dplyr::case_when(), but utilizes data.table::fifelse() in the background for improved performance.

Usage

case_when(..., .default = NA, .ptype = NULL, .size = NULL)

Arguments

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

Examples

df <- tidytable(x = 1:10)

df %>%
  mutate(case_x = case_when(x < 5 ~ 1,
                            x < 7 ~ 2,
                            TRUE ~ 3))
