Equal-length columns presented as a table, R's standard rectangular format. R object catalogue
Computed over every cell in the object, reading it as one vector. It stands in for a per-column list: 1,012 columns of one type, described whole.
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. With no per-column list, this is what says whether the columns differ from one another.
| Margin | Min. | 1st Qu. | Median | Mean | 3rd Qu. | Max. | Std. dev |
|---|---|---|---|---|---|---|---|
| Rows | 0.096838 | 0.92811 | 1.2223 | 1.3251 | 1.501 | 62.859 | 2.0962 |
| Columns | 0.032009 | 0.087196 | 0.15508 | 1.3251 | 0.48151 | 452.5 | 14.723 |
The column means vary far more than the row means, so what separates the values runs across the columns.
All 1,012 columns hold integer values, so this object is described whole rather than column by column. A list of one type repeated 1,012 times says less than a summary over every cell, and no column is left out of that summary. See Values and Margins above.
