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