anyMissing: Checks if there are any missing values in an object or not
In matrixStats: Methods that apply to rows and columns of a matrix

Checks if there are any missing values in an object or not.

1	anyMissing(x, ...)

`x`	A `vector`, a `list`, a `matrix`, a `data.frame`, or `NULL`.
`...`	Not used.

The implementation of this method is optimized for both speed and memory. The method will return TRUE as soon as a missing value is detected.

Returns TRUE if a missing value was detected, otherwise FALSE.

Henrik Bengtsson

Starting with R v3.1.0, there is anyNA() in the base, which provides the same functionality as this function.
