In eeptools: Convenience Functions for Education Data

a function to convert numeric factors into numeric class objects

Description

This function allows you to convert directly from a numeric factor to the numeric class in R and strip away the underlying level index of a factor. This makes it safer to convert from factors to numeric characters directly without accidentally misassigning numbers.

Usage

makenum(x)

Arguments

x	a factor with numeric levels

Details

This function should only be used on factors where all levels are valid numbers that can be coerced into a numeric class.

Value

A numeric

Note

This will force all levels to be converted to characters and then to numeric objects. Leading zeroes will be stripped off and commas will cause errors.
