R: Extract Posterior Draws

as.data.frame.brmsfit {brms}

R Documentation

Extract Posterior Draws

Description

Extract posterior draws in conventional formats as data.frames, matrices, or arrays.

Usage

## S3 method for class 'brmsfit'
as.data.frame(
  x,
  row.names = NULL,
  optional = TRUE,
  pars = NA,
  variable = NULL,
  draw = NULL,
  subset = NULL,
  ...
)

## S3 method for class 'brmsfit'
as.matrix(x, pars = NA, variable = NULL, draw = NULL, subset = NULL, ...)

## S3 method for class 'brmsfit'
as.array(x, pars = NA, variable = NULL, draw = NULL, subset = NULL, ...)

Arguments

`x`	A `brmsfit` object or another R object for which the methods are defined.
`row.names, optional`	Unused and only added for consistency with the `as.data.frame` generic.
`pars`	Deprecated alias of `variable`. For reasons of backwards compatibility, `pars` is interpreted as a vector of regular expressions by default unless `fixed = TRUE` is specified.
`variable`	A character vector providing the variables to extract. By default, all variables are extracted.
`draw`	The draw indices to be select. Subsetting draw indices will lead to an automatic merging of chains.
`subset`	Deprecated alias of `draw`.
`...`	Further arguments to be passed to the corresponding `as_draws_*` methods as well as to `subset_draws`.

Value

A data.frame, matrix, or array containing the posterior draws.
