Interactive function to build an l1 model specification for setup_glm_pipeline

Description

Interactive function to build an l1 model specification for setup_glm_pipeline

Usage

build_l1_models(
  gpa = NULL,
  trial_data = NULL,
  l1_model_set = NULL,
  from_spec_file = NULL,
  onset_cols = NULL,
  onset_regex = ".*(onset|time).*",
  duration_cols = NULL,
  duration_regex = ".*duration.*",
  value_cols = NULL,
  value_regex = NULL,
  isi_cols = NULL,
  isi_regex = "^(iti|isi).*"
)

Arguments

gpa	a glm_pipeline_arguments object containing an analysis pipeline to which $l1_models should be added. If $l1_models is already present, these will be amended.
trial_data	a data.frame containing trial-level data for one or more subjects
l1_model_set	optional existing l1_model_set to be modified
from_spec_file	optional YAML or JSON file containing settings to populated into l1 models
onset_cols	an optional character vector of columns in trial_data that should be in the set of event onsets
onset_regex	an optional PCRE-compatible regular expression for identifying potential event onset columns in trial_data
duration_cols	an optional character vector of columns in trial_data that should be in the set of event durations
duration_regex	an optional PCRE-compatible regular expression for identifying potential event duration columns in trial_data
value_cols	an optional character vector of columns in trial_data that should be in the set of signal values
value_regex	an optional PCRE-compatible regular expression for identifying potential event value columns in trial_data
isi_cols	an optional character vector of columns in trial_data that should be in the set of signal isi/iti
isi_regex	an optional PCRE-compatible regular expression for identifying potential isi/iti columns in trial_data

Details

if gpa is not passed in, then we will work from trial_data and l1_model_set.

Value

a l1_model_set object containing events, signals, and models, compatible with build_design_matrix
