reproducer (version 0.4.2)

ExtractExperimentData: ExtractExperimentData

Description

This function reads datasets from a defined directory in the reproducer package that hold the results of a family crossover experiments in the long format. It converts the data to the wide format if required.

Usage

ExtractExperimentData(
  DataSet,
  ExperimentNames,
  idvar = "ParticipantID",
  timevar = "Period",
  ConvertToWide = TRUE
)

Value

A list with an entry for the data for each experiment. If ConvertToWide is TRUE, it returns the data in the wide format otherwise it returns the data as it was read. Within each list item the data is returned as a tibble #importFrom stats # importFrom tibble # importFrom base

Arguments

DataSet

This is a tibble holding the data for each crossover experiment in a family (a family can include only one experiment).

ExperimentNames

This is a list with the full names of each experiment.

idvar

This is the name of the column that contains the data for specific participants. It is only assumed to be unique within an experiment (default idvar="ParticipantID").

timevar

This is the name of the table column that defines which data was collected in a specific time period. This function assumes that there are only two time periods (default timevar="Period").

ConvertToWide

This determine whether the function converts the data to the wide format (default ConvertToWide=TRUE).
