Makes available for use outside the quantmod workflow a dataset
of appropriately transformed variables, using the same mechanism
underlying specifyModel
. Offers the ability to apply transformations
to raw data using a common formula mechanism, without having to explicitly
merge different data objects.
Interally calls specifyModel
followed by modelData
, with the
returned object being coerced to the desired 'return.class' if possible,
otherwise returns a zoo
object.
See getSymbols
and specifyModel
for more information
regarding proper usage.
