Description

Internal method to sample expanded data

Usage

sample_expanded_data(
  object,
  p_control,
  period = NULL,
  subset_condition = NULL,
  seed
)

## S4 method for signature 'te_datastore'
sample_expanded_data(
  object,
  p_control,
  period = NULL,
  subset_condition = NULL,
  seed
)

Arguments

object	An object of class te_datastore.
p_control	Probability of selecting a control.
period	An integerish vector of non-zero length to select trial period(s) or NULL (default) to select all trial periods.
subset_condition	A string or NULL.
seed	An integer seed or NULL (default).

Value

A data.frame of class data.table.

Examples

# Data object normally created by [expand_trials]
datastore <- new("te_datastore_datatable", data = te_data_ex$data, N = 50139L)

sample_expanded_data(datastore, period = 260:275, p_control = 0.2, seed = 123)
