tfplot.forecastCov {dse} R Documentation

## Plots of Forecast Variance

### Description

Generate plots of forecast variance calculated by forecastCov.

### Usage

## S3 method for class 'forecastCov'
tfplot(x, ...,
series = 1:dim(x$forecastCov[[1]])[2], select.cov = 1:length(x$forecastCov), select.true =TRUE,
select.zero =TRUE, select.trend =TRUE, y.limit = NULL, line.labels =FALSE,
lty = NULL, Legend = NULL, Title = NULL,
graphs.per.page = 5, mar=par()$mar, reset.screen=TRUE) ## S3 method for class 'forecastCovEstimatorsWRTdata' tfplot(x, series=1:dim(x$forecastCov[[1]])[2],
select.cov=1:length(x$forecastCov), select.zero=TRUE, select.trend=TRUE, graphs.per.page = 5, mar=par()$mar, reset.screen=TRUE, lty=NULL, ...)

### Arguments

 x The result of forecastCov. series integer or string indicating the series which should be plotted. select.cov logical indicating that for the case of multiple models select the covariance to be plotted. select.true logical indicating that results from the forecast of the true model (if available) should be plotted. select.zero logical indicating that results from a forecast of zero should be plotted. select.trend logical indicating that results from a forecast of trend should be plotted. graphs.per.page The number of graphs to put on a page. mar plot margins (see par). reset.screen logical indicating if the plot window should be cleared before starting. lty see details. Legend optional legend passed to legend. Title optional legend passed to title (but see details). y.limit optional limit on the y scale. Covariance values larger than y.limit will not be shown. line.labels logical indicating line labels should be printed. ... For forecastCov objects this allows additional objects to be plotted. For forecastCovEstimatorsWRTdata ... are passed to other methods.

### Details

This function produces plots of the variance at different horizons. Output graphics can be paused between pages by setting par(ask=TRUE). If lty is NULL (default) it is set to seq(length(select.cov) +select.true+select.zero+select.trend), and corrected if these are TRUE but not in the object.

The Title is not put on the plot if the global option PlotTitles is FALSE. This can be set with options(PlotTitles=FALSE). This provides a convenient mechanism to omit all titles when the title may be added separately (e.g. in Latex).
