split.Seurat: Split an Assay

In SeuratObject: Data Structures for Single Cell Data

Split an Assay

Description

Split an Assay

Usage

## S3 method for class 'Seurat'
split(x, f, drop = FALSE, assay = NULL, layers = NA, ...)

Arguments

x	An Assay5 object
f	a ‘factor’ in the sense that as.factor(f) defines the grouping, or a list of such factors in which case their interaction is used for the grouping. If x is a data frame, f can also be a formula of the form ~ g to split by the variable g, or more generally of the form ~ g1 + ... + gk to split by the interaction of the variables g1, ..., gk, where these variables are evaluated in the data frame x using the usual non-standard evaluation rules.
drop	logical indicating if levels that do not occur should be dropped (if f is a factor or a list).
layers	Names of layers to include in the split; pass NA for all layers; pass NULL for the default layer
...	Ignored

Value

Depends on the value of ret:

• “assay”: x with the layers requested in layers split based on f; all other layers are left as-is

• “multiassay”: a list of Assay5 objects; the list contains one value per split and each assay contains only the layers requested in layers with the key set to the split

• “layers”: a list of matrices of length length(assays) * length(unique(f)); the list is named as “layer.split”
