ifelse1

Conditional Data Selection

Description

Places values into an object according to the logical values in test.

Usage

ifelse1(test, x, y, ...)

Arguments

`test`	logical object. Missing values (NA) are allowed
`x`	action to be taken if test is TRUE
`y`	action to be taken if test is FALSE
`...`	other

Details

NA values in test cause NAs in the result. Compared with ifelse() in Splus, the length of test in ifelse1() is 1, which means ifelse1() will do only one test.

Value

x or y depending on test.
