logScoreMultDirPrepare: Internal functions.

In rjbgoudie/structmcmc: Structural inference for Bayesian Networks and Variable Selection.

Description

Convert a data frame to the appropriate format for the fast/incremental logScoreMultDir functions, and return as part of the logScoreParameters list.

Usage

  logScoreMultDirPrepare(data, logScoreParameters,
    checkInput = T)

Arguments

data	A data.frame, with columns being factors giving the values of each random variable.
logScoreParameters	A list, optionally containing other parameters. In particular, it may contain 'hyperparameters'. data A matrix (NOT data.frame), with columns being integers in the range 0, 1, 2, .... giving the values of each random variable. **** The integers MUST start numbering at 0 NOT 1 **** nl A numeric vector of length ncol(data), specifying the number of levels that each random variable takes. hyperparameters A character vector of length one. Either "bdeu", "qi", "one", or "point9"
checkInput	A logical of length 1, specifying whether to check the inputs to the function.

Details

In particular, the data is converted to a matrix, and the factor levels taken integer values from 0, 1, .... ie not on 1, 2, 3.

Value

A list with the contents of logScoreParameters, with the following components added or altered:

data

A matrix (NOT data.frame), with columns being integers in the range 0, 1, 2, .... giving the values of each random variable.

nl

A numeric vector of length ncol(data), specifying the number of levels that each random variable takes.
