convertToLevels: convertToLevels

In lwTools/agriTrf: Agricultural Transformation Package: data management, depiction and modelling

Description

convertToLevels takes as input a column (dfCol), the allowed number of levels (numLevels) for the column, and the number of class divisions (numBreaks) and casts the numeric entries of the column to factor classes. If the column dfCol is already of class factor then the column is returned as it is (see example 2 below).

Usage

convertToLevels(dfCol, numLevels, numBreaks)

Arguments

dfCol	a column of a data.frame object whose entries have to be cast into factor classes. Note that this is not a character string but the column itself (refer to examples).
numLevels	an integer indicating the allowed number of different numeric values.
numBreaks	an integer indicating the number of class divisions (or exact boundaries) that should be taken.

Value

convertToLevels returns an object of class factor which contains the newly created levels (factor classes) from the entries in the column dfCol.

Examples

convertToLevels(iris[,"Sepal.Length"],4,5)
convertToLevels(iris[,"Species"],3,5)
