Parse Formulas of brms Models


Parse formulas objects for use in brms.


brmsterms(formula, ...)

## Default S3 method:
brmsterms(formula, ...)

## S3 method for class 'brmsformula'
brmsterms(formula, check_response = TRUE, resp_rhs_all = TRUE, ...)

## S3 method for class 'mvbrmsformula'
brmsterms(formula, ...)



An object of class formula, brmsformula, or mvbrmsformula (or one that can be coerced to that classes): A symbolic description of the model to be fitted. The details of model specification are explained in brmsformula.


Further arguments passed to or from other methods.


Logical; Indicates whether the left-hand side of formula (i.e. response variables and addition arguments) should be parsed. If FALSE, formula may also be one-sided.


Logical; Indicates whether to also include response variables on the right-hand side of formula .$allvars, where . represents the output of brmsterms.


This is the main formula parsing function of brms. It should usually not be called directly, but is exported to allow package developers making use of the formula syntax implemented in brms. As long as no other packages depend on this functions, it may be changed without deprecation warnings, when new features make this necessary.


An object of class brmsterms or mvbrmsterms (for multivariate models), which is a list containing all required information initially stored in formula in an easier to use format, basically a list of formulas (not an abstract syntax tree).
