hablar (version 0.3.0)

if_else_: if_this_else_that_

Description

A vectorised if or else function. It checks that the true or false (or the optional missing) arguments have the same type. However it accepts a generic NA. Built upon dplyr's [if_else()] function. The only difference is that the user do not have to specify the type of NA. if_else_ is faster than base [ifelse()] and a tad slower than dplyr's [if_else()]. Attributes are taken from either true or false because one generic NA.

Usage

if_else_(condition, true, false, missing = NULL)

Value

Details

If the returning vector have attributes (e.g. for factors) it returns the attributes for the first non-generic NA in the order true, false and then missing.
