as.rstack {rstackdeque} | R Documentation |
Create an rstack pre-filled from a given input
Description
Creates a new rstack from a given input. Coerces input to a
list first using as.list
, the element at x[[1]]
becomes the top of the new rstack.
Usage
as.rstack(x, ...)
Arguments
x |
input to convert to a stack. |
... |
additional arguments to be passed to or from methods. |
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.rstack
results in a stack of
columns, rather than a stack of rows.
Value
a new rstack.
