Description Usage Arguments Author(s) Examples
This function was created to make the different kinds of data classes at
least seem more fungible. It allows the user to pass in a data
object without being concerned that the function requires a matrix,
data.frame, vector, xts, or timeSeries object. By using checkData
,
the function "knows" what data format it has to work with.
