The length of a string means the total number of characters present in a given string.
For example, the string
"Programiz" has the length 9.
In R, there are two ways to find the length of a string. We can use the
str_length() function from the
Example 1: Length of a String in R Using nchar()
# create a string string1 <- "Programiz" # use nchar() to find length of string1 result <- nchar(string1) cat("Total Length:", result)
Total Length: 9
In the above example, we have used the
nchar() function to find the length of a string variable named string1.
Since string1 contains a string
"Programiz", which has a total of 9 characters. So
nchar() returns 9.
Example 2: Length of a String in R Using str_length()
In order to use the
str_length() function, we first import the
# import stringr package library(stringr) string1 <- "Programiz" # use str_length() of stringr package to find length result <- str_length(string1) cat("Total length:", result)
Total length: 9
Here, we have used the
str_length() function provided by the
stringr package to find the length of string1.
