Calculating the Dot Product in R

To calculate the dot product in R, you can use the %*% operator. The dot product of two vectors is the sum of the products of their corresponding elements. Here's how you can do it step by step:

1. Create Vectors: First, create two vectors, let's say v1 and v2, containing the elements you want to find the dot product of.

2. Calculate the Dot Product: Use the %% operator to calculate the dot product of the two vectors. For example, if v1 and v2 are the vectors, the dot product can be calculated as v1 %% v2.

3. Example: ``` # Create vectors v1 <- c(1, 2, 3) v2 <- c(4, 5, 6)

# Calculate the dot product dot_product <- v1 %*% v2 ```

The dot_product variable will now contain the result of the dot product calculation.
