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.

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")
