Create a netmeta object from a gemtc object

Description

Auxiliary function to create a netmeta object from a gemtc object (experimental feature).

Usage

gemtc2netmeta(
  x,
  keep.samples = TRUE,
  level = gs("level"),
  level.ma = gs("level.ma"),
  reference.group = levels(x$model$network$treatments$id)[1],
  baseline.reference = gs("baseline.reference"),
  small.values = gs("small.values"),
  all.treatments = gs("all.treatments"),
  seq = gs("seq"),
  backtransf = gs("backtransf"),
  nchar.trts = gs("nchar.trts"),
  nchar.studlab = gs("nchar.studlab")
)

Arguments

`x`	A `gemtc` object created with R package gemtc.
`keep.samples`	A logical indicating whether to keep the generated samples.
`level`	The level used to calculate confidence intervals for individual comparisons.
`level.ma`	The level used to calculate confidence intervals for network estimates.
`reference.group`	Reference treatment (first treatment is used if argument is missing).
`baseline.reference`	A logical indicating whether results should be expressed as comparisons of other treatments versus the reference treatment (default) or vice versa. This argument is only considered if `reference.group` has been specified.
`small.values`	A character string specifying whether small treatment effects indicate a beneficial (`"desirable"`) or harmful (`"undesirable"`) effect (passed on to `netrank`, can be abbreviated.
`all.treatments`	A logical or `"NULL"`. If `TRUE`, matrices with all treatment effects, and confidence limits will be printed.
`seq`	A character or numerical vector specifying the sequence of treatments in printouts.
`backtransf`	A logical indicating whether results should be back transformed in printouts and forest plots. If `backtransf = TRUE`, results for `sm = "OR"` are presented as odds ratios rather than log odds ratios, for example.
`nchar.trts`	A numeric defining the minimum number of characters used to create unique treatment names (see Details).
`nchar.studlab`	A numeric defining the minimum number of characters used to create unique study labels.

Value

A netmeta object with additional class "netmeta.gemtc".

Examples


if (requireNamespace("gemtc", quietly = TRUE)) {
library("gemtc")
# Load the example network and generate a consistency model:
model <- mtc.model(smoking, type="consistency")
results <- mtc.run(model, thin = 10)
detach("package:gemtc")

# Print results in netmeta layout
mtc <- gemtc2netmeta(results)
mtc
# SUCRAs
netrank(mtc)
# Rankogram
rankogram(mtc)
}
