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

In This article, we will discuss how we Create a Vector of sequenced elements in R Programming Language using seq() Function.

What are sequenced elements?

Sequenced elements mean things that are placed in a particular order, one after another. This concept is often used in various fields.

seq() Function

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

Creating a Vector of sequenced using seq() Function

#Create sequence elements
seq(1:10)

Output:

[1]  1  2  3  4  5  6  7  8  9 10

Creating a Vector of sequenced using by arguments

# R Program to illustrate 
# the use of seq() Function 
  
# Creating vector using seq() 
vec1 <- seq(1, 10, by = 2)

vec1

Output:

[1] 1 3 5 7 9

Creating a Vector of sequenced using from and to arguments

# R Program to illustrate 
# the use of seq() Function 

# Creating vector using seq() 
vec1 <- seq(from=22,to=44)
vec1

Output:

[1] 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

Seq() function with argument length.out

# Using seq() with length.out argument
result_vector <- seq(from = 1, to = 10, length.out = 5)
print(result_vector)

Output:

[1]  1.00  3.25  5.50  7.75 10.00

The length.out argument is set to 5, meaning that R will create a sequence of length 5 starting from 1 to 10. The result will be a sequence evenly spaced between 1 and 10 with a length of 5.
