Create a matrix of output plots from a brmsfit object

A pairs method that is customized for MCMC output.

# S3 method for 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.

Examples

if (FALSE) {
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)
