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

1

Arguments

x

input to convert to an rdeque.

...

additional arguments to be passed to or from methods (ignored).

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.

Value

a new rdeque.
