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.
| Margin | Min. | 1st Qu. | Median | Mean | 3rd Qu. | Max. | Std. dev |
|---|---|---|---|---|---|---|---|
| Rows | 0.48475 | 0.5344 | 0.55356 | 0.56066 | 0.58327 | 0.70915 | 0.035297 |
| Columns | 0.0083473 | 0.32053 | 0.57429 | 0.56066 | 0.8389 | 0.98664 | 0.28238 |
The column means vary far more than the row means, so what separates the values runs across the columns.

Columns
This object is 1,279 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.
