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

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

Answer

To get all possible substrings of a string in R, you can use a combination of substrings and nested loops to generate all substrings.

✐ Examples

1 All Substrings of 'Hello'

In this example,

We create a variable named str with a value of 'Hello'.
We initialize an empty vector named substrings to store all substrings.
We use nested loops to iterate through each possible start and end index combination.
For each combination, we extract the substring using substring function and add it to the substrings vector.
Finally, we print the substrings vector.

R Program

str <- 'Hello'
substrings <- character()
for (i in 1:nchar(str)) {
  for (j in i:nchar(str)) {
    substrings <- c(substrings, substr(str, i, j))
  }
}
print(substrings)

Output

[1] "H"    "He"   "Hel"  "Hell" "Hello" "e"    "el"   "ell"  "ello" "l"    "ll"   "llo"  "lo"   "o"
