`vecNA`

computes the frequency of missing values in an atomic vector.
`vecNA`

is essentially a wrapper for `sum`

or `mean`

+
`is.na`

or `!is.na`

and can be useful for functional programming
(e.g., `lapply(FUN = vecNA)`

). It is also used by other functions in the
quest package related to missing values (e.g., `mean_if`

).

`x` |
atomic vector or list vector. If not a vector, it will be coerced to
a vector via |

`prop` |
logical vector of length 1 specifying whether the frequency of missing values should be returned as a proportion (TRUE) or a count (FALSE). |

`ov` |
logical vector of length 1 specifying whether the frequency of observed values (TRUE) should be returned rather than the frequency of missing values (FALSE). |

numeric vector of length 1 providing the frequency of missing values
(or observed values if `ov`

= TRUE). If `prop`

= TRUE, the value
will range from 0 to 1. If `prop`

= FALSE, the value will range from 1
to `length(x)`

.
