seq2: Increasing sequence of integers in an interval
Description
These helpers take two endpoints and return the sequence of all
integers within that interval. For seq2_along(), the upper
endpoint is taken from the length of a vector. Unlike
base::seq(), they return an empty vector if the starting point is
a larger integer than the end point.
Usage
seq2(from, to)
seq2_along(from, x)
Arguments
from
The starting point of the sequence.
to
The end point.
x
A vector whose length is the end point.
Value
An integer vector containing a strictly increasing
sequence.
