The length of a vector means the total number of elements present in a given vector.
In R, we can use the
length() function to find the total number of elements present in a vector.
Example: Length of a Vector in R Using length()
# create a vector languages <- c("R", "Swift", "Java", "Python") # find length of languages vector length(languages) # 4 # create another vector numbers <- c(1,5,7,9,12,54) # find length of numbers vector length(numbers) # 6
 4  6
In the above example, we have used the
length() function to find the length of the vector named languages and numbers respectively.
- languages contain 4 elements, the function 4.
- numbers contain 6 elements, the function 6.
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.
