Mapping levels

Description

mapLevels produces a map with information on levels and/or internal integer codes. As such can be conveniently used to store level mapping when one needs to work with internal codes of a factor and later transfrorm back to factor or when working with several factors that should have the same levels and therefore the same internal coding.

Usage

mapLevels(x, codes=TRUE, sort=TRUE, drop=FALSE, combine=FALSE, ...)

mapLevels(x) <- value

## Default S3 method:
mapLevels(x, codes, sort, drop, combine, ...)

## S3 method for class 'character'
mapLevels(x, codes, sort, drop, combine, ...)

## S3 method for class 'factor'
mapLevels(x, codes, sort, drop, combine, ...)

## S3 method for class 'list'
mapLevels(x, codes, sort, drop, combine, ...)

## S3 method for class 'data.frame'
mapLevels(x, codes, sort, drop, combine, ...)

.unlistLevelsMap(x, ind = FALSE)

## S3 method for class 'levelsMap'
print(x, ...)

## S3 method for class 'listLevelsMap'
print(x, ...)

## S3 method for class 'levelsMap'
x[i]

## S3 method for class 'listLevelsMap'
x[i]

is.levelsMap(x)

is.listLevelsMap(x)

.isCharacterMap(x)

as.levelsMap(x, check = TRUE, ...)

as.listLevelsMap(x, check = TRUE)

.checkLevelsMap(x, method)

.checkListLevelsMap(x, method)

## S3 method for class 'levelsMap'
c(..., sort = TRUE, recursive = FALSE)

## S3 method for class 'listLevelsMap'
c(..., sort = TRUE, recursive = FALSE)

## S3 method for class 'levelsMap'
sort(x, decreasing = FALSE, na.last = TRUE, ...)

## S3 method for class 'levelsMap'
unique(x, incomparables = FALSE, ...)

mapLevels(x) <- value

## Default S3 replacement method:
mapLevels(x) <- value

## S3 replacement method for class 'list'
mapLevels(x) <- value

## S3 replacement method for class 'data.frame'
mapLevels(x) <- value

Arguments

x	object whose levels will be mapped, look into details codes boolean, create integer levelsMap (with internal codes) or character levelsMap (with level names)
codes	boolean, create integer levelsMap (with internal codes) or character levelsMap (with level names)
sort	boolean, sort levels of character x, look into details
drop	boolean, drop unused levels
combine	boolean, combine levels, look into details
...	additional arguments for sort
value	levelsMap or listLevelsMap, output of mapLevels methods or constructed by user, look into details
