Parse formulas objects for use in brms.

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