Time Series Value, Velocity and Acceleration Plot

Source: R/ts-vva-plot.R
ts_vva_plot.Rd

This function will produce three plots faceted on a single graph. The three graphs are the following:

  • Value Plot (Actual values)

  • Value Velocity Plot

  • Value Acceleration Plot

Usage

ts_vva_plot(.data, .date_col, .value_col)

Arguments

.data

The data you want to visualize. This should be pre-processed and the aggregation should match the .frequency argument.

.date_col

The data column from the .data argument.

.value_col

The value column from the .data argument

Value

The original time series augmented with the differenced data, a static plot and a plotly plot of the ggplot object. The output is a list that gets returned invisibly.

Details

This function expects to take in a data.frame/tibble. It will return a list object that contains the augmented data along with a static plot and an interactive plotly plot. It is important that the data be prepared and have at minimum a date column and the value column as they need to be supplied to the function. If your data is a ts, xts, zoo or mts then use ts_to_tbl() to convert it to a tibble.
