Example 1: Creating Vector with Intervals Using seq() Function

In this example, I’ll show how to create a vector consisting of numeric intervals using the seq function in R.

Have a look at the R code below:

x1 <- seq(from = 100,              # Applying seq function
          to = 200,
          by = 10)
x1                                 # Print vector with intervals
# 100 110 120 130 140 150 160 170 180 190 200

As you can see based on the previous output of the RStudio console, we have created a numeric vector ranging from 100 to 200 with intervals of 10.

Example 2: Extracting Every nth Element from Vector Using seq() Function

This example shows how to use the seq function to extract vector elements based on a specific interval.

For this example, we’ll use the LETTERS object, which is already provided by the basic installation of the R programming language:

LETTERS                            # Print LETTERS object
# "A" "B" "C" "D" "E" "F" "G" "H" "I" "J" "K" "L" "M" "N" "O" "P" "Q" "R" "S" "T" "U" "V" "W" "X" "Y" "Z"

Let’s assume that we want to extract every fifth element of this LETTERS vector. Then, we can apply the following R code:

x2 <- LETTERS[seq(from = 1,        # Subset using seq function
                  to = length(LETTERS),
                  by = 5)]
x2                                 # Print subset of LETTERS
# "A" "F" "K" "P" "U" "Z"

Looks good!
