Summary method for objects of class netcomb

Description

Summary method for objects of class netcomb.

Usage

## S3 method for class 'netcomb'
summary(
  object,
  common = object$common,
  random = object$random,
  overall.hetstat = object$overall.hetstat,
  backtransf = object$backtransf,
  nchar.comps = object$nchar.comps,
  warn.deprecated = gs("warn.deprecated"),
  ...
)

Arguments

object	An object of class netcomb.
common	A logical indicating whether results for the common effects model should be printed.
random	A logical indicating whether results for the random effects model should be printed.
overall.hetstat	A logical indicating whether to print heterogeneity measures.
backtransf	A logical indicating whether results should be back transformed in printouts and forest plots.
nchar.comps	A numeric defining the minimum number of characters used to create unique component names.
warn.deprecated	A logical indicating whether warnings should be printed if deprecated arguments are used.
...	Additional arguments (to catch deprecated arguments).
