get_formula(model, ...)

## Default S3 method:
get_formula(model, ...)

## S3 method for class 'brmsfit'
get_formula(model, resp = NULL, dpar = NULL, ...)

Arguments

model

The fitted model object.

...

Ignored.

resp

For brmsfit objects, the response variable for which the formula is desired. brmsfit objects may have multiple formulas, so this selects a particular one. If NULL, the first formula is chosen (unless dpar is specified).

dpar

For brmsfit objects, the distributional variable for which the formula is desired. If NULL, no distributional parameter is used. If there are multiple responses with distributional parameters, then resp should be specified or else the first formula will be used by default.
