Increasing sequence of integers in an interval
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.
seq2(from, to) seq2_along(from, x)
from |
The starting point of the sequence. |
to |
The end point. |
x |
A vector whose length is the end point. |
An integer vector containing a strictly increasing sequence.
seq2(2, 10) seq2(10, 2) seq(10, 2) seq2_along(10, letters)
