R – Vector Length

To get length of a vector in R programming, call length() function and pass the vector to it. length() function returns an integer, representing the length of vector.

In this tutorial, we will learn how to use length() function to find the length of a vector, with examples.

Syntax

The syntax to use length() function to get the length of a vector x is

</> Copy length(x)

Return Value

The function returns an integer.

Examples

In the following program, we take a vector in x, and find its length using length() function.

example.R

</> Copy x <- c(2, 4, 6, 8) vectorLength = length(x) cat("Length of vector x is :", vectorLength)

Output

Length of vector x is : 4

Now, let us take a vector of strings, and find its length.

example.R

</> Copy x <- c("az", "bc", "mn") vectorLength = length(x) cat("Length of vector x is :", vectorLength)

Output

Length of vector x is : 3

Conclusion

In this R Tutorial, we learned how to find the length of a vector, using length() function, with the help of examples.
