A single vector with a dim attribute. All elements share one type. R object catalogue
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.
| Margin | Min. | 1st Qu. | Median | Mean | 3rd Qu. | Max. | Std. dev |
|---|---|---|---|---|---|---|---|
| Rows | -0.30424 | -0.07845 | -0.052693 | -0.061686 | -0.041426 | -0.010209 | 0.033796 |
| Columns | -1.0061 | -0.081131 | -0.03232 | -0.061442 | -0.001185 | 0.060785 | 0.10251 |
The column means vary far more than the row means, so what separates the values runs across the columns.

This object is 922 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.

Dimensions is the row and column count. Missing is how many values were recorded as absent. Distinct is how many different values were counted in the object. Value summary is the six-number summary of the values and their spread.
