Description

Create a training set (data.frame) from a time series using a sliding window.

Usage

CasesSeries(t, W, start = 1, end = length(t))

Arguments

t	a time series (numeric vector).
W	a sliding window (with time lags, numeric vector).
start	starting period.
end	ending period.

Details

Check reference for details.

Value

Returns a data.frame, where y is the output target and the inputs are the time lags.
