# Creating a Vector of sequenced elements in R Programming – seq() Function

• Last Updated : 04 Jun, 2020

`seq()` function in R Language is used to create a sequence of elements in a Vector. It takes the length and difference between values as optional argument.

Syntax:
seq(from, to, by, length.out)

Parameters:
from: Starting element of the sequence
to: Ending element of the sequence
by: Difference between the elements
length.out: Maximum length of the vector

Example 1:

 `# R Program to illustrate``# the use of seq() Function`` ` `# Creating vector using seq()``vec1 <``-` `seq(``1``, ``10``, by ``=` `2``)`` ` `vec2 <``-` `seq(``1``, ``10``, length.out ``=` `7``)`` ` `# Printing vectors``print``(vec1)``print``(vec2)`

Output:

``` 1 3 5 7 9
  1.0  2.5  4.0  5.5  7.0  8.5 10.0
```

Example 2:

 `# R Program to illustrate``# the use of seq() Function`` ` `# Creating vector using seq()``vec1 <``-` `seq(``10``, ``1``, by ``=` `-``2``)`` ` `vec2 <``-` `seq(``10``, ``1``, length.out ``=` `4``)`` ` `# Printing vectors``print``(vec1)``print``(vec2)`

Output:

``` 10  8  6  4  2
 10  7  4  1
```
