R: Infinite

is.inf {splus2R} | R Documentation

## Infinite

### Description

`is.inf` returns a vector of the same length as the input object, indicating which elements are infinite (not missing).

### Usage

      is.inf(x)

### Arguments

`x` | object to be tested

### Details

This calls `is.infinite`.

This returns a vector of the same length as `x`; the `j`th element is `TRUE` if `x[j]` is infinite (i.e., equal to one of `Inf` or `-Inf`). This will be `FALSE` if `x` is not numeric or complex. Complex numbers are infinite if either the real and imaginary part is.

    is.inf(Inf)
    # [1] TRUE
    is.inf(NA)
    # [1] FALSE
    is.inf(1)
    # [1] FALSE
