Finding the most repeated character in a string in R

Question

On this string "apple", I want to execute a test to see which character has the most occurring in the string, which is "p".

I have used the str_extract_all("apple"), and turn the list into a tibble, use group_by() and summarise() to return the most occurring character.

I would like to ask if there's an easier way to do this task?

Answer 1

You can easily separate every character and calculate their occurrence using a table and return the one with max frequency.

most_repeated_character <- function(x) {

  tab <- table(strsplit(x, '')[[1]])

  names(tab)[tab == max(tab)]

}

most_repeated_character('apple')

#[1] "p"

most_repeated_character('potato')

#[1] "o" "t"
