Recipe Objective

Vector is a type of object or data structure in R-language. They are designed to store multiple values of same data-type. For example: if you want to store different 50 food items for each cuisine, you don't need to create 50 variables for each cuisine but just a vector of length 50 of datatype character.

Note: It can not have a combination of any two datatype. It has to be homogeneous in nature.

This recipe demonstrates how to find the length of a vector

Step 1: Creating a vector

We use combine function "c()" to create a vector

Example: Vector food_items with data of 3 different cuisine of character datatype

food_items = c("pasta", "burrito", "butter chicken")

Using class function to check the datatype of the vector

class(food_items)
'character'

Step 2: Length of a vector

We use length() function to find the length of vector or the number of elements

length(food_items)
3
