Auto-Plot a Random Walk

Plot a random walk with side-by-side facets showing both the random variable and cumulative product (random walk path).

Usage

ts_random_walk_plot(.data, .interactive = FALSE)

Arguments

.data

The data from ts_random_walk() function.

.interactive

The default is FALSE, TRUE will produce an interactive plotly plot.

Value

A ggplot2 object or an interactive plotly plot

Details

This function will take output from the ts_random_walk() function and create a side-by-side faceted plot. The left panel shows the random variable (y) over time, and the right panel shows the cumulative product (cum_y, i.e., the random walk path) over time. Each simulation run is shown as a separate line. The legend is set to "none" if the simulation count is higher than 9.
