export(object, con,
    matrix=assayNames(object)[1], rownames_attr="rownames", colnames_attr="colnames")

Arguments

object

A LoomExperiment object to be exported. File must have the .loom extension.

con

The connection from which data is loaded or to which data is saved. If this is a character vector, it is assumed to be a filename and a corresponding file connection is created and then closed after exporting the object. If a RTLFile derivative, the data is loaded from or saved to the underlying resource.

matrix

A matrix in which the column and rows for the Loom file will be derived. The default argument is dervied from the the first assay in the LoomExperiment object.

rownames_attr

A character vector indicating the name of the rowData attribute to represent the names rownames in the LoomExperiment object.

colnames_attr

A character vector indicating the name of the colData attribute to represent the names colnames in the LoomExperiment object.

Value

An error code indiciating whether the operation was successful.
