R: Number of Valid Cases

nvalid {rapportools} | R Documentation

## Number of Valid Cases

### Description

Returns the number of valid (non-`NA`) values in a variable. This is a wrapper around `univar` function with `length` function passed in `fn` argument, but with missing values previously removed. However, it's not possible to cancel `NA` omission with this function (doing so will yield error).

### Usage

    nvalid(...)

### Arguments

`...` | parameters to be passed to `univar` function

### Value

a numeric value with number of valid (non-NA) vector elements
