augment_synthetic: Add jointly resampled source variables to existing data

In simulab: Simulates a Wide Variety of Data Shapes, Sizes and Distributions

Add jointly resampled source variables to existing data

Description

Add jointly resampled source variables to existing data

Usage

augment_synthetic(data, source, variables = NULL, seed = NULL)

Arguments

data	Destination base data.frame.
source	Source base data.frame.
variables	Variables to resample. NULL, the default, resamples every variable in source.
seed	Optional random seed.

Value

A simulab_sim base data.frame with the resampled variables added, one source row drawn per row of data. as.data.frame(x, what = "provenance") gives the source row each destination row was drawn from.

Examples

source_data <- data.frame(x = stats::rnorm(100))
data <- data.frame(id = 1:20)
result <- augment_synthetic(data, source = source_data, variables = "x", seed = 1)
head(result)
