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.
