variable.names.tramME: Return variable names.

In tramME: Transformation Models with Mixed Effects

Return variable names.

Description

Returns the variable names corresponding to different variable groups in a tramME model.

Usage

## S3 method for class 'tramME'
variable.names(
  object,
  which = c("all", "response", "grouping", "shifting", "interacting", "smooth", "ranef"),
  ...
)

Arguments

object	a tramME object (fitted or unfitted)
which	all: all variables, response: response variable, grouping: grouping factors for random effects, shifting: shifting variables, interacting: interacting variables, smooth: variables in smooth terms, ranef: all random effects variables (covariates with random slopes and grouping factors).
...	optional parameters

Details

The returned names are the names as they are used by tramME. For example, when the response is a Surv object, variable.names returns the name of that object, and not the names of the variables used to create it.

Value

A vector of variable names.

Examples

data("sleepstudy", package = "lme4")
mod <- LmME(Reaction ~ Days + (Days | Subject), data = sleepstudy, nofit = TRUE)
variable.names(mod)
variable.names(mod, "response")
