rstackdeque (version 1.1.1)

as.rdeque: Create a pre-filled rdeque from a given input

Description

Creates a new rdeque from a given input. Coerces input to a list first using as.list, the element at x[[1]] becomes the front of the new rdeque.

Usage

as.rdeque(x, ...)

Arguments

x
input to convert to an rdeque.
...
additional arguments to be passed to or from methods (ignored).

Value

a new rdeque.

Details

Runs in $O(N)$ in the size of the input. Because data.frames return a list of columns when run through as.list, running as.rdeque results in a deque of columns, rather than a deque of rows.
