hashFactor: Create a hashFactor

Description

Creates a hashFactor object, which operates in much the same way as a factor, but doesn't require a continuous sequence of integers for the levels.

Usage

hashFactor(x = character(), levels, codes)

Arguments

x

The values to be encoded into a factor

levels

The labels associated with each level of the factor

codes

the integer codes associated with each level of the factor

Examples

fac <- hashFactor(sample(LETTERS[1:5], 10, replace=TRUE),
	levels=LETTERS[1:5], codes=c(1,5,8,2,6))
d <- data.frame(i=11:20, f=fac)
