GraphicsVisualisation is often the first step in understanding the patterns in time series data. The package uses ggplot2 to produce customisable graphics to visualise time series patterns. 


Auto and Cross Covariance and Correlation plots 

Seasonal plot 

Seasonal subseries plots 

Ensemble of time series displays 

Ensemble of time series residual diagnostic plots 

Lag plots 

Plot characteristic ARMA roots 

DecompositionsUseful for decomposing a time series into some simpler structural components.
