How to get all the possible K length Substrings in a String in R - Step by Step Examples

How to get all the possible K length Substrings in a String in R ?

Answer

To get all possible K length substrings of a string in R, you can use substring operations and nested loops to iterate through each possible substring.

✐ Examples

1 All Substrings of Length 3 in 'Hello World'

In this example,

We create a variable str with a value of "Hello World".
We initialize an empty vector substrings to store all substrings of length 3.
We use nested loops to iterate through each possible start and end index for the substring.
Within the loops, we extract the substring using substring operations and add it to the substrings vector.
Finally, we print the substrings vector.

R Program

str <- 'Hello World'
k <- 3
substrings <- character()
for (i in 1:(nchar(str) - k + 1)) {
  for (j in i:(i + k - 1)) {
    substrings <- c(substrings, substr(str, i, j))
  }
}
print(paste('All substrings of length', k, ':', substrings, collapse = ', '))

Output

[1] "All substrings of length 3 : Hel, ell, llo, lo , o W,  Wo, Wor, orl, rld"

Summary
