** seq_along()** function in R Language is used to generate a sequence of the same length of the argument passed.

Syntax:seq_along(x)

Parameters:

x:specified arguments

**Example 1:**

`# R program to illustrate ` `# seq_along function ` ` ` `# Calling the seq_along() function ` `seq_along(letters[` `1` `:` `4` `]) ` `seq_along(letters[` `0` `:` `3` `]) ` |

[1] 1 2 3 4 [1] 1 2 3

**Example 2:**

`# R program to illustrate ` `# seq_along function ` ` ` `# Calling the seq_along() function ` `seq_along(c(` `1` `, ` `2` `, ` `3` `)) ` `seq_along(c(` `5` `, ` `10` `, ` `15` `, ` `20` `)) ` `seq_along(c(` `2` `, ` `4` `)) ` `seq_along(` `10` `) ` `seq_along(` `2` `) ` |
