Create a single reusable model specification for subsequent buildModel calls.
An object of class
quantmod is created that can be then be reused with different
modelling methods and parameters. No data frame is specified, as data is retrieved
from potentially multiple environments, and internal calls to getSymbols.

remove all incomplete rows.
Models are specified through the standard formula mechanism.
As financial models may include a
variety of financial and economic indicators,
each differing in source, frequency, and/or class,
a single mechanism to specify sources is
included within a call to specifyModel.

how this process works.

All symbols are first retrieved from the global environment, without inheritence.
If an object is not found in the global environment, it is added to a
list of objects to load through the

It is possible to include any supported series in the formula by simply specifying the object's symbol. See *Details* for a list of currently supported classes.
