selectBestModel {celda} | R Documentation

## Select best chain within each combination of parameters

### Description

Select the chain with the best log likelihood for each combination of tested parameters from a `SCE` object gererated by celdaGridSearch or from a `celdaList` object.

### Usage

    selectBestModel(x, asList = FALSE, altExpName = "featureSubset")

    ## S4 method for signature 'SingleCellExperiment'
    selectBestModel(x, asList = FALSE, altExpName = "featureSubset")

    ## S4 method for signature 'celdaList'
    selectBestModel(x, asList = FALSE)

### Arguments

`x` | Can be one of A SingleCellExperiment object returned from `celdaGridSearch`, `recursiveSplitModule`, or `recursiveSplitCell`. Must contain a list named `"celda_grid_search"` in `metadata(x)`. celdaList object.
`asList` | `TRUE` or `FALSE`. Whether to return the best model as a `celdaList` object or not. If `FALSE`, return the best model as a corresponding celda model object.
`altExpName` | The name for the altExp slot to use. Default "featureSubset".

### Value

One of

- A new SingleCellExperiment object containing one model with the best log-likelihood for each set of parameters in `metadata(x)`. If there is only one set of parameters, a new SingleCellExperiment object with the matching model stored in the metadata `"celda_parameters"` slot will be returned. Otherwise, a new SingleCellExperiment object with the subset models stored in the metadata `"celda_grid_search"` slot will be returned.

- A new `celdaList` object containing one model with the best log-likelihood for each set of parameters. If only one set of parameters is in the `celdaList`, the best model will be returned directly instead of a `celdaList` object.

### Examples

    data(sceCeldaCGGridSearch)
    ## Returns same result as running celdaGridSearch with "bestOnly = TRUE"
    sce <- selectBestModel(sceCeldaCGGridSearch)
    data(celdaCGGridSearchRes)
    ## Returns same result as running celdaGridSearch with "bestOnly = TRUE"
    cgsBest <- selectBestModel(celdaCGGridSearchRes)
