About this object
Sparse and compact storageEmpty outlines inside brackets stand for the matrix a reader prints, and it is not in the file. What the file holds is below: shorter rows of cells tagged i, p, x and Dim, which together are enough to rebuild it, and nothing is in any of them.as printedin the fileipxDim

The standard sparse matrix format in compressed-column form. Non-zero entries are kept as row indices i, column pointers p, values x, and a Dim pair. R object catalogue

Values

Computed over the stored entries only, not over every cell. The implicit zeros are excluded.

Columns

This object is 2,700 columns wide. A dgCMatrix 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 its stored entries: see Values above.

Structure fingerprint

28 other datasets carry the same structure fingerprint. That fingerprint is a digest of the column names and their types, and a dgCMatrix carries neither, so a match is not another object with the same columns. Nor is it one of the same width: on this kind the same fingerprint is carried at more than one width. The datasets are not listed, because that is not a list of anything this one is related to.
