make_analysis_set: Make analysis set

In nncc: Nearest Neighbors Matching of Case-Control Data

Make analysis set

Description

Set a maximum number of controls that are allowed to be matched to a case; ensure that matched case-control pairs have a distance closer than the predefined threshold; merge strata sharing same controls.

Usage

make_analysis_set(
  var,
  stratified_data,
  data,
  maxdist = 0,
  maxcontrols = 20,
  silent = FALSE
)

Arguments

var	Character of current exposure variable in make_analysis_sets
stratified_data	Stratified dataset, see make_knn_strata
data	Original case control data
maxdist	Reject any controls more than maxdist from their case
maxcontrols	Maximum number of controls to keep per strata
silent	Suppress exposure info useful for *apply/loop implementations

Details

For more information, please refer to the vignette using browseVignettes("nncc").

Value

A list of data frames with the length of number of exposures.
