Description Usage Arguments Value See Also Examples
This is equivalent to if(test) x else y . The main advantage of using this function is better formatting, and a more natural syntax when the result is being assigned; see examples below.
With 5 arguments, this is equivalent to if(test1) x else if(test2) u else v (where arguments are given by name, not position).
In ifelse1, isNumericAtomicVector, test should be a single value, and the calculations for y (or x) are not performed if it is not selected. In contrast, for ifelse, test is normally a vector, both x and y are evaluated, even if not used, and x and y are vectors the same length as test.

x |
any object; this is returned if test is TRUE. |

there should be 3, 5, 7, etc. arguments to this function; arguments 1, 3, 5, etc. should be logical values; the other arguments (even numbered, and last) are objects that may be returned. |
with three arguments, one of x or y. With k arguments, one of arguments 2, 4, ..., k-1, k.
