Exercise

# Multidimensional scaling in three dimensions

In this exercise, you will perform multidimensional scaling of all numeric columns of the `wine`

data, specifying three dimensions for the final representation.

Instructions

**100 XP**

- Exclude the first column containing the wine type and compute the distance matrix for all other columns and assign it to an object
`wine.dist`

. - Compute the multidimensional scaling of the data to represent the distance in three dimensions.
- Use the
`scatterplot3d()`

function to plot the representation and color them by wine type.
