modSearch: Generate an empty dataframe to match 'modAcc' lists

In jknowles/EWStools: Tools for automating the testing and evaluation of education early warning system models

Description

Used for generating the data to make good looking ROC curves of training and test data.

Usage

modSearch(methods, ...)

Arguments

methods	a list of train method names to generate the dataframe for
...	additional arguments passed to modTest

Details

The sensitivities and specificities come from the roc object stored in the ROCit object

Value

a data.frame with the following columns:

• sens - the sensitivities of the model at various thresholds

• spec - the specificities of the model at various thresholds

• grp - whether the model is using training or test data

• auc - the area under the curve

• method - the model method

• elapsedTime - the time reported for the model to run

Note

Currently the arguments passed to modSearch are evaluated in the parent frame. This means that you cannot pass list elements or data.frame elements to the parameters of modSearch that get passed along to modTest via .... Instead, you need to declare them as separate variables in the parent environment and save them there.
