ifelse: Conditional Element Selection

In jonmcalder/refactor: Better factor handling for R

Description

Conditional Element Selection

Usage

ifelse(test, yes, no, ...)

Arguments

test	an object which can be coerced to logical mode.
yes	return values for true elements of test.
no	return values for false elements of test.
...	further arguments to be passed to cfactor.

Details

A refined version of ifelse that allows for factor appending.

Value

If either yes or no are of class factor, the function returns an object of class factor whereas levels are determined using cfactor internally. Otherwise, the base method is called directly.

Examples

f <- factor(c('c','a','a',NA,'b','a'), levels= c('a','b','c'))
base::ifelse(is.na(f), "g", f) # not nice
refactor::ifelse(is.na(f), "g", f) # probably what you wanted
