sdcMicro (version 4.5.0)

globalRecode: Global Recoding

Description

Global recoding

Usage

globalRecode(obj,...)#, column,breaks, labels, method="equidistant")

Arguments

obj

vector of class numeric or of class factor with integer labels for recoding or an object of class sdcMicroObj

column

which keyVar should be changed

...

see possible arguments below

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

• the modified sdcMicroObj or a factor, 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.

Examples

data(free1)
head(globalRecode(free1[,"AGE"], breaks=c(1,9,19,29,39,49,59,69,100), labels=1:8))
table(globalRecode(free1[,"AGE"], breaks=c(1,9,19,29,39,49,59,69,100), labels=1:8))
table(globalRecode(free1[,"AGE"], breaks=c(1,9,19,29,39,49,59,69,100)))
table(globalRecode(free1[,"AGE"], breaks=6))
table(globalRecode(free1[,"AGE"], breaks=6, method="logEqui"))
table(globalRecode(free1[,"AGE"], breaks=6, method="equalAmount"))

## for objects of class sdcMicro:
data(testdata2)
sdc <- createSdcObj(testdata2,
  keyVars=c('urbrur','roof','walls','water','electcon','relat','sex'), 
  numVars=c('expend','income','savings'), w='sampling_weight')
sdc <- globalRecode(sdc, column="urbrur", breaks=5)
