Estimate k-nearest neighbours graph from a TourExperiment object

Estimate k-nearest neighbours graph from a TourExperiment object

estimate_neighbors(.data, num_neighbors, .on = NULL,
  .engine = BiocNeighbors::KmknnParam())

Arguments

.data	a TourExperiment object
num_neighbors	An integer scalar for number of neighbors
.on	a character scalar, indicating the part of .data to estimate nearest neighbors. If missing the first assay will be used.
.engine	A BiocNeighbor::BiocNeighborParam() object that reperesents the algorithm used to compute nearest neighbors.

Value

A TourExperiment object with the neighborSets slot filled.

Details

The representation of the nearest neighbors is a matrix of size ncol(.data) by num_neighbors containing the neighbor indexes for each sample in .data
