Estimate Lun simulation parameters

Estimate simulation parameters for the Lun simulation from a real dataset.

lunEstimate(counts, params = newLunParams())

# S3 method for SingleCellExperiment
lunEstimate(counts, params = newLunParams())

# S3 method for matrix
lunEstimate(counts, params = newLunParams())

Arguments

counts	either a counts matrix or an SingleCellExperiment object containing count data to estimate parameters from.
params	LunParams object to store estimated values in.

Value

LunParams object containing the estimated parameters.

Details

The nGenes and nCells parameters are taken from the size of the input data. No other parameters are estimated. See LunParams for more details on the parameters.

Examples

# Load example data
library(scater)
set.seed(1)
sce <- mockSCE()

params <- lunEstimate(sce)
