Convert numbers to English words

Description

This can be helpful when writing reports with knitr/rmarkdown if we want to print numbers as English words in the output. The function n2w() is an alias of numbers_to_words().

Usage

numbers_to_words(x, cap = FALSE, hyphen = TRUE, and = FALSE)

n2w(x, cap = FALSE, hyphen = TRUE, and = FALSE)

Arguments

`x`	A numeric vector. The absolute values should be less than `1e15`.
`cap`	Whether to capitalize the first letter of the word. This can be useful when the word is at the beginning of a sentence. Default is `FALSE`.
`hyphen`	Whether to insert hyphen (-) when the number is between 21 and 99 (except 30, 40, etc.).
`and`	Whether to insert `and` between hundreds and tens, e.g., write 110 as “one hundred and ten” if `TRUE` instead of “one hundred ten”.

Value

A character vector.
