parameters |
A object generated by |
other_prior |
A list with names of certain parameters. Some methods need
extra parameters to execute the estimation step, so you must input them. In
simulation step, the number of cells, genes, groups, batches, the percent of
DEGs are usually customed, so before simulating a dataset you must point it out.
See |
return_format |
A character. Alternative choices: list, SingleCellExperiment,
Seurat, h5ad. If you select |
verbose |
Logical. Whether to return messages or not. |
seed |
A random seed. |
In phenopath, users can only set nCells
and nGenes
to specify the number of cells and genes in the
simulated dataset. See Examples
for instructions.
For more customed parameters, see splatter::PhenoParams()
and splatter::phenoSimulate()
