This section involves understanding the depth of each and every attribute that is considered to be important for the dataset indicated:

1. To get a feel for the data as per the attribute structure, use the following code:

> class(GlassDataset)
[1] "tbl_df" "tbl" "data.frame"

The output shows that the dataset is merely a tabular format of the data frame.
