| as.rpqueue {rstackdeque} | R Documentation |
Create a pre-filled rpqueue from a given input
Description
Creates a new rpqueue from a given input. Coerces input to a
list first using as.list, the element at x[[1]] becomes the front of the new queue.
Usage
as.rpqueue(x, ...)
Arguments
x |
input to convert to an rpqueue. |
... |
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.rpqueue results in a queue of
columns, rather than a queue of rows.
Value
a new rpqueue.
