Compatibility wrapper for stored column-wise sparse top-k selection

run_sparse_stored_topk_by_column() preserves the stored-entry column-wise interface used in earlier releases. New code should call run_sparse_topk_stored() with by = "col".

Usage

run_sparse_stored_topk_by_column(x, k, decreasing = TRUE)

Arguments

x

A dgCMatrix (or something coercible to one).

k

Number of top entries to retain per column or row. Must be a positive integer.

decreasing

Whether to sort in decreasing order (largest values first). Default is TRUE.

Value

A list with idx and value matrices as described in run_sparse_topk_stored().
