dyngen_estimation | R Documentation |
This function is used to estimate useful parameters from a real dataset by
using infer_trajectory
function in dynwrap package.
dyngen_estimation(ref_data, verbose = FALSE, other_prior, seed)
ref_data |
A count matrix. Each row represents a gene and each column represents a cell. |
verbose |
Logical. |
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 |
seed |
An integer of a random seed. |
In dyngen, users can input cell group information if it is available. If cell
group information is not provided, the procedure will detect cell groups by
kmeans automatically.
See Examples
for more instructions.
A list contains the estimated parameters and the results of execution detection.
