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

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.**seq()**

Syntax:

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

Parameters:from:Starting element of the sequenceto:Ending element of the sequenceby:Difference between the elementslength.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] 1 3 5 7 9 [1] 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:**

[1] 10 8 6 4 2 [1] 10 7 4 1
