indices: Get indices of matched set

In nullranges/nullranges: Generation of null ranges via bootstrapping or covariate matching

Get indices of matched set

Description

Extracts the indices of a specified matched set from a Matched object.

Usage

indices(x, set = "matched", ...)

## S4 method for signature 'Matched'
indices(x, set)

Arguments

x	Matched object.
set	A character string describing from which set to extract indices. can be one of 'focal', 'matched', 'pool', or 'unmatched'.
...	Additional arguments.

Details

Indices from 'focal' come from the focal set of matchRanges() used to construct the Matched object while indices from 'matched', 'pool', and 'unmatched' come from the pool set. Default returns the 'matched' indices from the pool set.

Value

An integer vector corresponding to the indices in the focal or pool which comprise the "focal" or c("matched", "pool", "unmatched") sets.

Examples

set.seed(123)
mdf <- makeExampleMatchedDataSet(matched = TRUE)
head(indices(mdf))

head(indices(mdf, set = 'focal'))
head(indices(mdf, set = 'pool'))
head(indices(mdf, set = 'matched'))
head(indices(mdf, set = 'unmatched'))
