Description Usage Arguments Details Examples

View source: R/objects.R

Description

Create an Assay object from a feature (e.g. gene) expression matrix. The expected format of the input matrix is features x cells.

Usage

1
CreateAssayObject(counts, data, min.cells = 0, min.features = 0)

Arguments

counts

Unnormalized data such as raw counts or TPMs

data

Prenormalized data; if provided, do not pass counts

min.cells

Include features detected in at least this many cells. Will subset the counts matrix as well. To reintroduce excluded features, create a new object with a lower cutoff.

min.features
