| summary.varFunc {nlme} | R Documentation |
A structName attribute, with the value of corresponding
argument, is appended to object and its class is changed to
summary.varFunc.
## 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.
