count a string length in R

nchar("sample string")

This code calculates the length of a given string. The nchar() function is used in R to measure the length of a given string, which is passed as an argument inside the parentheses. So, in this example, the string “sample string” is passed as an argument and when the code is executed, it will return the length of the string. The length is returned as the number of characters which includes letters, spaces, and any other characters. In this example, the result will be 13 as it is a string of 13 characters.
