R: Expanded "which"-like functionality.

mwhich-methods {bigmemory} | R Documentation

## Expanded “which”-like functionality.

### Description

Implements `which`-like functionality for a `big.matrix`, with additional options for efficient comparisons (executed in C++); also works for regular numeric matrices without the memory overhead. test

### Methods

signature(x = "big.matrix=", cols = "ANY", vals = "ANY",", " comps = "ANY", op = "character")

  ...

signature(x = "big.matrix", cols = "ANY", vals = "ANY",", " comps = "ANY", op = "missing")

  ...

signature(x = "matrix", cols = "ANY", vals = "ANY",", " comps = "ANY", op = "character")

  ...

signature(x = "matrix", cols = "ANY", vals = "ANY",", " comps = "ANY", op = "missing")

  ...
