LunParams: The LunParams class

In Oshlack/splatter: Simple Simulation of Single-cell RNA Sequencing Data

The LunParams class

Description

S4 class that holds parameters for the Lun simulation.

Parameters

The Lun simulation uses the following parameters:

nGenes

The number of genes to simulate.

nCells

The number of cells to simulate.

[nGroups]

The number of groups to simulate.

[groupCells]

Vector giving the number of cells in each simulation group/path.

[seed]

Seed to use for generating random numbers.

Mean parameters

[mean.shape]

Shape parameter for the mean gamma distribution.

[mean.rate]

Rate parameter for the mean gamma distribution.

Counts parameters

[count.disp]

The dispersion parameter for the counts negative binomial distribution.

Differential expression parameters

[de.nGenes]

The number of genes that are differentially expressed in each group

[de.upProp]

The proportion of differentially expressed genes that are up-regulated in each group

[de.upFC]

The fold change for up-regulated genes

[de.downFC]

The fold change for down-regulated genes

The parameters not shown in brackets can be estimated from real data using lunEstimate. For details of the Lun simulation see lunSimulate.
