seq is short for sequence. A sequence is an ordered list of objects (or events). Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. Sometimes, sequence is used as a generic name for both list, array and set for convenience.

Creating a repeating sequence in R
I need to create a pattern like this with the rep() and seq() commands.
It should look like this:
[1] 0.0 0.0 0.0 0.8 0.8 0.8 1.6 1.6 1.6 2.4 2.4 2.4 3.2 3.2 3.2 4.0 4.0 4.0 4.8
[20] 4.8 4.8
Do you have any idea how to do so?
