autoplot.ts: Automatically create a ggplot for time series objects

In pli2016/forecast: Forecasting Functions for Time Series and Linear Models

Description

autoplot takes an object of type ts or mts and creates a ggplot object suitable for usage with stat_forecast.

fortify.ts takes a ts object and converts it into a data frame (for usage with ggplot2).

Usage

## S3 method for class 'ts'
autoplot(object, series = NULL, ...)
## S3 method for class 'mts'
autoplot(object, colour=TRUE, facets=FALSE, ...)
## S3 method for class 'ts'
autolayer(object, colour=TRUE, series=NULL, ...)
## S3 method for class 'mts'
autolayer(object, colour=TRUE, series=NULL, ...)
## S3 method for class 'ts'
fortify(model,data, ...)

Arguments

object	Object of class “ts” or “mts”.
series	Identifies the timeseries with a colour, which integrates well with the functionality of geom_forecast.
facets	If TRUE, multiple time series will be faceted (and unless specified, colour is set to FALSE). If FALSE, each series will be assigned a colour.
colour	If TRUE, the time series will be assigned a colour aesthetic
model	Object of class “ts” to be converted to “data.frame”.
data	Not used (required for fortify method)
...	Other plotting parameters to affect the plot.

Value

None. Function produces a ggplot graph.
