LEM-combine: LEM combining methods

In SingleCellExperiment: S4 Classes for Single Cell Data

Description

Methods to combine LinearEmbeddingMatrix objects.

Usage

## S4 method for signature 'LinearEmbeddingMatrix'
rbind(..., deparse.level=1)

## S4 method for signature 'LinearEmbeddingMatrix'
cbind(..., deparse.level=1)

Arguments

...	One or more LinearEmbeddingMatrix objects.
deparse.level	An integer scalar; see ?base::cbind for a description of this argument.

Details

For rbind, LinearEmbeddingMatrix objects are combined row-wise, i.e., rows in successive objects are appended to the first object. This corresponds to adding more samples to the first object. Note that featureLoadings and factorData will only be taken from the first element in the list; no checks are performed to determine whether they are consistent or not across objects.

For cbind, LinearEmbeddingMatrix objects are combined columns-wise, i.e., columns in successive objects are appended to the first object. This corresponds to adding more factors to the first object. featureLoadings will also be combined column-wise across objects, provided that the number of features is the same across objects. Similarly, factorData will be combined row-wise across objects.

Combining objects with and without row names will result in the removal of all row names; similarly for column names. Duplicate row names are currently supported by duplicate column names are not, and will be de-duplicated appropriately.

Value

A LinearEmbeddingMatrix object containing all rows/columns of the supplied objects.
