How to Get Length of a Vector in R - Step by Step Examples

How to Get Length of a Vector in R ?

To get the length of a vector in R, you can use the length function.

In this example,

We first create a numeric vector named num_vector with a set of numeric values using the c function, which combines the values into a vector.
We use the length function to determine the number of elements in num_vector. The length function takes a vector as its argument and returns the number of elements in that vector.
We assign the result of the length function to a variable named num_vector_length.
Finally, we print the length of the vector using the print function to display the value of num_vector_length on the console.

num_vector <- c(10, 20, 30, 40, 50)
num_vector_length <- length(num_vector)
print(num_vector_length)

In this example,

We first create a character vector named char_vector with a set of string values using the c function, which combines the string values into a vector.
We use the length function to determine the number of elements in char_vector. The length function takes a vector as its argument and returns the number of elements in that vector.
We assign the result of the length function to a variable named char_vector_length.
Finally, we print the length of the vector using the print function to display the value of char_vector_length on the console.

char_vector <- c("apple", "banana", "cherry")
char_vector_length <- length(char_vector)
print(char_vector_length)
