as.data.frame.brmsfit: Extract Posterior Draws

In brms: Bayesian Regression Models using 'Stan'

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.
