buildNNIndex {BiocNeighbors} | R Documentation |
Build indices for nearest-neighbor searching with different algorithms.
buildNNIndex(..., BNPARAM=NULL)
... |
Further arguments to be passed to individual methods.
The mandatory argument for all methods is |
BNPARAM |
A BiocNeighborParam object specifying the type of index to be constructed.
This defaults to a KmknnParam object if |
Supplying a KmknnParam object as BNPARAM
will dispatch to buildKmknn
.
Supplying an AnnoyParam object as BNPARAM
will dispatch to buildAnnoy
.
A BiocNeighborIndex object containing indexing structures for each algorithm.

buildKmknn
and buildAnnoy
for specific methods.
