Confidence Intervals on Coefficients

Description:

     Confidence intervals on the parameters associated with the model
     represented by 'object' are obtained. This function is generic;
     method functions can be written to handle specific classes of
     objects. Classes which already have methods for this function
     include: 'gls', 'lme', and 'lmList'.

Usage:

     intervals(object, level, ...)

Arguments:

  object: a fitted model object from which parameter estimates can be
          extracted.

   level: an optional numeric value for the interval confidence level.
          Defaults to 0.95.

     ...: some methods for the generic may require additional
          arguments.

Value:

     will depend on the method function used; see the appropriate
     documentation.
