Modeler-class represents (parametrized but not yet
fit) statistical models that can predict binary outcomes. The
Modeler function is used to construct objects of this class.

Additional parameters required for the specific kind of classificaiton model that will be constructed. See Details.
Objects of the
Modeler-class provide a general
abstraction for classification models that can be learned from one
data set and then applied to a new data set. Each type of classifier
is likely to have its own specific parameters. For instance, a
K-nearest neighbors classifier requires you to specify
more complex classifier, PCA-LR has many more parameters, including
the false discovery rate (
alpha) used to select features and
the percentage of variance (
perVar) that should be explained by
the number of principal components created from those features. All
adeditional parameters should be suplied as named arguments to the
Modeler constructor; these addityional parameters will be
bundled into a list and inserted into the
params slot of the
resulting object of the
Modeler-class. The examples
illustrate how to do this for three different kinds of classifiers.

training data and make predictions on new test data.

about the kinds of objects produced by
Modeler-package for a list of the kinds of
classifiers that have been adapted for use in this generic framework.
