Usage

h_mmrm_tmb_formula_parts(
  formula,
  covariance = as.cov_struct(formula, warn_partial = FALSE)
)

formula: (formula)
Original formula.
covariance: (cov_struct)
A covariance structure from which additional formula parts should be added.

List of class mmrm_tmb_formula_parts with elements:

formula: the original input.
model_formula: formula with the covariance term is removed.
model_formula: formula with the covariance term removed.
full_formula: same as model_formula but includes the covariance structure's subject, visit and (optionally) group variables.
cov_type: string with covariance term type (e.g. "us").
is_spatial: flag indicator of whether the covariance structure is spatial
visit_var: character with the visit variable name.
subject_var: string with the subject variable name.
group_var: string with the group variable name. If no group specified, this element is NULL.
model_var: character with the variables names of the formula, except subject_var.
