In cppcontainers: 'C++' Standard Template Library Containers

Create deque

Description

Create a deque, i.e. a double-ended queue.

Usage

cpp_deque(x)

Arguments

x	An integer, numeric, character, or logical vector.

Details

C++ deque methods implemented in this package are assign, at, back, clear, emplace, emplace_back, emplace_front, empty, erase, front, insert, max_size, pop_back, pop_front, push_back, push_front, resize, shrink_to_fit, and size. The package also adds the == and [ operators and various helper functions (print, to_r, type).

All object-creating methods in this package begin with cpp_ to avoid clashes with functions from other packages, such as utils::stack and base::vector.
