About this object
A flat block of values with dimensionsA block of cells sharing every edge, with nothing above the columns and nothing in it: a name here is hung on the whole block rather than on one column.

A single vector with a dim attribute. All elements share one type. R object catalogue

Values

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

Margins

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 and the column means vary by a similar amount, so neither margin carries the structure on its own.

Columns

This object is 599 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.

The same data in 2 other packages

This data is identical to the data these packages carry, down to the byte. Where they call it something else, the other name is shown.

Structure fingerprint

1 other dataset carries 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 599 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.
