## S3 method for class 'varFunc'
summary(object, structName, ...)

`object`	an object inheriting from class `"varFunc"`, representing a variance function structure.
`structName`	an optional character string with a description of the `varFunc` class. Default depends on the method function: `"Combination of variance functions"` for `varComb`, `"Constant plus power of covariate"` for `varConstPower`, `"Exponential of variance covariate"` for `varExp`, `"Different standard deviations per stratum"` for `varIdent`, `"Power of variance covariate"` for `varPower`, and `data.class(object)` for `varFunc`.
`...`	some methods for this generic require additional arguments. None are used in this method.

an object similar to object, with an additional attribute structName, inheriting from class summary.varFunc.
