new.name                package:mgcv                R Documentation

Obtain a name for a new variable that is not already in use

Description:

     'gamm' works by transforming a GAMM into something  that can be
     estimated by 'lme', but this involves creating new  variables, the
     names of which should not clash with the names of other  variables
     on which the model depends. This simple service routine checks a 
     suggested name against a list of those in use, and if neccesary
     modifies it  so that there is no clash.

Usage:

      new.name(proposed,old.names)

Arguments:

proposed: a suggested name

old.names: An array of names that must not be duplicated

Value:

     A name that is not in 'old.names'.
