facRename.alldiffs {asremlPlus}R Documentation

Renames factors in the prediction component of an alldiffs.object.

Description

Renames factors in the prediction component of an alldiffs.object. These changes are propogated to the other components of the alldiffs.object.

Usage

## S3 method for class 'alldiffs'
facRename(object, factor.names, newnames,  ...)

Arguments

object

An alldiffs.object.

factor.names

A character containing the names of the factors in the prediction component of object that are to be renamed.

newnames

A character containing the new names of the factors in the prediction component of object.

...

Provision for passsing arguments to functions called internally - not used at present.

Value

A modified alldiffs.object.
