Description

xmuRAM2Ordinal: Convert a RAM model whose data contain ordinal variables to a threshold-based model

Usage

xmuRAM2Ordinal(model, verbose = TRUE, name = NULL)

Arguments

model	An RAM model to add thresholds too.
verbose	Tell the user what was added and why (Default = TRUE).
name	= A new name for the modified model. Default (NULL) = leave it as is).
