globalRecode: Global Recoding

Description

Global recoding

Usage

globalRecode(x, breaks, labels, method="equidistant")

Arguments

x

vector of class numeric or of class factor with integer labels for recoding

breaks

either a numeric vector of cut points or number giving the number of intervals which x is to be cut into.

labels

labels for the levels of the resulting category. By default, labels are constructed using "(a,b]" interval notation. If labels = FALSE, simple integer codes are returned instead of a factor.

method

method equidistant for equal sized intervalls method logEqui for equal sized intervalls for log-transformed data method equalAmount for interval

Value

• A factor is returned, unless labels = FALSE which results in the mere integer level codes.

Details

If a labels parameter is specified, its values are used to name the factor levels. If none is specified, the factor level labels are constructed.
