Standardise a probability distribution name

Converts a probability distribution name to the name used by R, so that distributions can be given with any capitalisation and by their full name as well as the R name. For example, "Negative binomial", "negbinom" and "nbinom" all give "nbinom".

Usage

.clean_distribution_name(x)

Arguments

x

A character string with the name of a probability distribution.

Value

A character string.

Details

Names are cleaned with .clean_string() before being matched, so capitalisation, surrounding whitespace, and underscores or hyphens in place of spaces are all accepted. Names that are not recognised as an alias are returned cleaned but otherwise unchanged, leaving them to be validated by the calling function.
