SingleR.Combine: Combining SingleR objects together to one object.
In dviraran/SingleR: Reference-based single-cell RNA-seq annotation

This function can be useful when the memory is insufficient to analyze the whole counts matrix. We can analyze subsets of the full data and combine them together afterwards.

1 2	SingleR.Combine(singler.list, order = NULL, clusters = NULL, expr = NULL, xy = NULL)

`singler.list`	a list of SingleR objects
`order`	a vector of the cells name to order the SingleR object by. Important if there is a pre-built single-cell object, and the order of cells in SingleR needs to be in the same order.
`clusters`	a vector of clusters per cell. Optional.
`expr`	the counts matrix. Optional.
`xy`	the t-SNE coordinates of all cells.
