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)

Value

An integer vector containing a strictly increasing sequence.

Arguments

from

The starting point of the sequence.

to

The end point.

x

A vector whose length is the end point.

Examples

seq2(2, 10)
seq2(10, 2)
seq(10, 2)

seq2_along(10, letters)
