BFBayesFactorList-class {BayesFactor} | R Documentation

## General S4 class for representing a collection of Bayes factor model comprisons, each against a different denominator

### Description

The `BFBayesFactorList` class is a general S4 class for representing models model comparison via Bayes factor. See the examples for demonstrations of BFBayesFactorList methods.

### Usage

    ## S4 method for signature 'BFBayesFactorList'
    t(x)

    ## S4 method for signature 'numeric,BFBayesFactorList'
    e1 / e2

    ## S4 method for signature 'BFBayesFactorList,index,index,missing'
    x[i, j, ..., drop = TRUE]

    ## S4 method for signature 'BFBayesFactorList,index,missing,missing'
    x[i, j, ...,
      drop = TRUE]

    ## S4 method for signature 'BFBayesFactorList,missing,index,missing'
    x[i, j, ...,
      drop = TRUE]

### Arguments

`x` | a BFBayesFactorList object
`e1` | Numerator of the ratio
`e2` | Denominator of the ratio
`i` | indices specifying rows to extract
`j` | indices specifying columns to extract
`...` | further arguments passed to related methods
`drop` | unused

### Details

`BFBayesFactorList` objects inherit from lists, and contain a single slot:

version

  character string giving the version and revision number of the package that the model was created in

Each element of the list contains a single `"BFBayesFactor"` object. Each element of the list must have the same numerators, in the same order, as all the others. The list object is displayed as a matrix of Bayes factors.

### Examples

    ## Compute some Bayes factors to demonstrate Bayes factor lists
    data(puzzles)
    bfs <- anovaBF(RT ~ shape*color + ID, data = puzzles, whichRandom = "ID", progress=FALSE)

    ## Create a matrix of Bayes factors
    bfList <- bfs / bfs
    bfList

    ## Use indexing to select parts of the 'matrix'
    bfList[1,]
    bfList[,1]

    ## We can use the t (transpose) function as well, to get back a BFBayesFactor
    t(bfList[2,])

    ## Or transpose the whole matrix
    t(bfList)
