irtree_fit_mirt: Fit an 'irtree_model' using mirt
In hplieninger/ItemResponseTrees: IR-Tree Modeling in 'mirt', 'Mplus', or 'TAM'

This function takes a data frame and a model object and runs the model in mirt.

irtree_fit_mirt(
  object = NULL,
  data = NULL,
  link = "logit",
  verbose = interactive(),
  control = control_mirt(),
  improper_okay = FALSE
)

`object`	Object of class `irtree_model`. See irtree_model for more information.
`data`	Data frame containing containing one row per respondent and one column per variable. The variable names must correspond to those used in `object`.
`link`	String specifying the link function. Only `logit` is implemented in mirt.
`verbose`	Logical indicating whether output should be printed to the console.
`control`	List. The allowed elements of this list depend on the `engine`. Use `control_mirt()`, `control_mplus()`, or `control_tam()` for convenience. Note that the `fit()` function does not use `...`, but that you can use the `control_*()` functions to pass additional arguments.
`improper_okay`	Logical indicating whether the model should also be fit if it is not a proper IR-tree model. Set this only to `TRUE` if you really know what you are doing.
