R: Create a matrix of output plots from a 'brmsfit' object

pairs.brmsfit {brms} | R Documentation

## Create a matrix of output plots from a `brmsfit` object

### Description

A `pairs` method that is customized for MCMC output.

### Usage

    ## S3 method for class 'brmsfit'
    pairs(x, pars = NA, variable = NULL, regex = FALSE, fixed = FALSE, ...)

### Arguments

`x` | An object of class `brmsfit`
`pars` | Deprecated alias of `variable`. Names of the parameters to plot, as given by a character vector or a regular expression.
`variable` | Names of the variables (parameters) to plot, as given by a character vector or a regular expression (if `regex = TRUE`). By default, a hopefully not too large selection of variables is plotted.
`regex` | Logical; Indicates whether `variable` should be treated as regular expressions. Defaults to `FALSE`.
`fixed` | (Deprecated) Indicates whether parameter names should be matched exactly (`TRUE`) or treated as regular expressions (`FALSE`). Default is `FALSE` and only works with argument `pars`.
`...` | Further arguments to be passed to `mcmc_pairs`.

### Details

For a detailed description see `mcmc_pairs`.

### Examples

    ## Not run:
    fit <- brm(count ~ zAge + zBase * Trt
               + (1|patient) + (1|visit),
               data = epilepsy, family = "poisson")
    pairs(fit, variable = variables(fit)[1:3])
    pairs(fit, variable = "^sd_", regex = TRUE)

    ## End(Not run)
