How to get the length of a string in R

In this tutorial we are going to learn about, how to find out the length of a string in R language.

The length of a string means total number of characters present in a given string.

Getting the string length

To get the length of a string, we can use the built in nchar() function in R.

The nchar() function takes the string as an argument and returns the number of characters in it or it returns 0 for the empty string (’ ’).

Here is an example, that gets the length of a string stored in the name variable.

name = 'gowtham'
length = nchar(name)
print(length)

Output:

[1] 7

Alternatively, we can use the str_length() function from a stringr package to get the length of a string in R.

library(stringr)

name = 'gowtham'
length = str_length(name)
print(length)
