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] 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
