celdaGridSearch.Rd
Yields assigments of genes/cells to clusters, depending on the provided model type.
celdaGridSearch(counts, model, params.test, params.fixed = NULL, max.iter = 200, nchains = 3, cores = 1, best.only = TRUE, seed = 12345, verbose = TRUE, logfile.prefix = "Celda")
counts | A count matrix. |
---|---|
model | Celda model. Options available in `celda::available.models`. |
params.test | List. A list denoting the combinations of parameters to run in a celda model. For example, "list(K=5:10, L=15:20)" will run all combinations of K from 5 to 10 and L from 15 to 20 in model 'celda_CG'. |
params.fixed | List. A list denoting additional parameters to use in each celda model. Default NULL. |
max.iter | Integer. Maximum number of iterations of Gibbs sampling to perform. Default 200. |
nchains | Integer. Number of random cluster initializations. Default 1. |
cores | Integer. The number of cores to use for parallel Gibbs sampling. Default 1. |
best.only | Logical. Whether to return only the chain with the highest log likelihood per combination of parameters or return all chains. Default TRUE. |
seed | Integer. Passed to set.seed(). Default 12345. |
verbose | Logical. Whether to print log messages during celda chain execution. Default TRUE. |
logfile.prefix | Character. Prefix for log files from worker threads and main process. Default "Celda". |
Object of class "celda_list", which contains results for all model parameter combinations and summaries of the run parameters
