modelPosition: Get parameter(s), result table row and rank of a model.
In benmack/oneClass: One-class classification in the absence of test data

Description Usage Arguments Value Examples

Given the parameter(s), results table row, or rank of a particular metric of the results table, the corresponding two informations are extracted.

1 2	modelPosition(x, modParam = NULL, modRow = NULL, modRank = NULL, by = NULL, decreasing = TRUE)

`x`	an object as returned from train.
`modParam`	data frame with the parameters of the model.
`modRow`	the row or index of the model in the model-selection table.
`modRank`	the rank of the model after sorting by `by`.
`by`	a character or character vector specifying by which column of the `x$results` table to sort. If `NULL` the performance metric is taken from the `train` object.
`decreasing`	only when `modRank` is used. `TRUE` (default) to sort in decreasing order. can be a vector if `by` is a vector.

a list with the parameter, row index and rank of the model.

                                    cMultiplier=c(10, 100)))
## get the position (in the results table) and parameters of model which is 
## on rank 3 according to the performance metric \'puAuc\'
