progress = getOption("bigKNN.progress", interactive())
)Arguments
- x
A
bigmemory::big.matrix, external pointer, or prepared reference.- metric
Distance metric. Supported values are
"euclidean","sqeuclidean", and"cosine".- memory_budget
Memory budget expressed in bytes or a compact size string such as
"2GB".- num_threads
Requested thread count forwarded to common BLAS/OpenMP environment variables during execution.
- progress
Logical flag controlling progress reporting for plan-aware calls.
