get_lower_upper_smart {dRiftDM} | R Documentation |
Turn default/special upper and lower arguments to vectors
Description
The function is used in the depths of the package to get the search space as a vector, matching with the free parameters of a model. Only relevant when users use the "default parameters" approach where they only specify the parameter labels and assume the package figures out how each parameter relates across conditions (see simulate_data). This comes in handy, when freeing a parameter across conditions, while the search space remains the same (otherwise, a user would always have to adapt the vectors for lower/upper to match with x2prms_vals)
Usage
get_lower_upper_smart(drift_dm_obj, lower, upper, labels = TRUE)
Arguments
drift_dm_obj |
an object of type drift_dm |
lower , upper |
either a vector or list (see create_matrix_l_u) |
labels |
optional logical, if |
Details
The function first gets all unique parameters across conditions using
prms_cond_combo. The unique parameter labels are then forwarded
to create_matrix_l_u, together with all (!) the conditions in the
model and the upper
/lower
arguments. Subsequently, the created matrices
are wrangled into vectors in accordance with prms_cond_combo. The
vectors are then passed back.
Value
a list with two vectors named lower/upper
that describe the search
space. The length and names (if requested) matches with
coef(model, select_unique = TRUE).
