unfactor: Purge factors

In gu-mi/GOglm: Length Bias Correction in Gene Ontology Enrichment Analysis Using Logistic Regression

Description

Removes all factors from a variable in a sensible way

Usage

  unfactor(var)

Arguments

var	The variable from which you want the factors removed

Details

As factors are their own type, to remove factors we must convert each level into another type. This is currently done using "typeless" behaviour: a factor is converted to a numeric vector if this can be done without inducing NAs, otherwise it is coerced using as.character. Currently supported types are: /codefactor, /codedata.frame and /codelist.

Value

The variable with all factors converted to characters or numbers

Note

This function is written by Matthew D. Young and is used in the goseq package.
