pmgetSignature {HiLDA} | R Documentation

## Obtain the parameters for mutation signatures and memberships

### Description

Obtain the parameters for mutation signatures and memberships

### Usage

    pmgetSignature(
      mutationFeatureData,
      K,
      numInit = 10,
      tol = 1e-04,
      maxIter = 10000
    )

### Arguments

`mutationFeatureData` | the mutation data (MutationFeatureData class (S4 class)) by the `hildaReadMPFile`.
`K` | the number of mutation signatures
`numInit` | the number of performing calculations with different initial values
`tol` | tolerance for the estimation (when the difference of log-likelihoods become below this value, stop the estimation)
`maxIter` | the maximum number of iteration of estimation

### Value

The output is an instance of EstimatedParameters S4 class, which stores estimated parameters and other meta-information, and will be used for saving parameter values and visualizing the mutation signatures and memberships

### Examples

    ## After obtaining G (see e.g., hildaReadMPFile function)
    load(system.file("extdata/sample.rdata", package="HiLDA"))
    Param <- pmgetSignature(G, K = 3)
