## Number agreement with a vector

### Description

This function chooses the singular or plural form of a word based on the length of an associated vector, or an integer.

### Usage

    pluralise(singular, x = NULL, n = NULL, plural = NULL)

### Arguments

`singular` | The singular form of the word.
`x` | A vector of any mode, whose length is used to choose the correct word form, unless `n` is specified.
`n` | An integer which is used to choose the correct word form (singular if n = 1, plural otherwise). Take priority over `x` if not `NULL`.
`plural` | The plural form of the word. If `NULL`, an 's' is simply appended to the singular form.

### Value

Either `singular` or `plural`, as appropriate.
