Time Series Splits Plot

Sometimes we want to see the training and testing data in a plot. This is a simple wrapper around a couple of functions from the timetk package.

Usage

ts_splits_plot(.splits_obj, .date_col, .value_col)

Arguments

.splits_obj

The predefined splits object.

.date_col

The date column for the time series.

.value_col

The value column of the time series.

Value

A time series cv plan plot

Details

You should already have a splits object defined. This function takes in three parameters, the splits object, a date column and the value column.
