Computed over every cell in the object, reading it as one vector.

The mean of each row, and of each column, summarised. Reading every cell as one vector gives a matrix and its transpose the same answer; these do not.

The row means vary far more than the column means, so what separates the values runs down the rows.

This object is 6 columns wide. A matrix carries no per-column schema, so its width is what the catalogue records and there is nothing to list one column at a time. What it holds is described whole instead, summarised over every cell: see Values and Margins above.

9 other datasets carry the same structure fingerprint. That fingerprint is a digest of the column names and their types, and a matrix carries neither, so on one it comes down to the width and the type held: a match is another object of 6 columns holding the same type rather than one with the same columns. The datasets are not listed, because that is not a list of anything this one is related to.
