Methods for Function `crossVal` in Package x12

Description

Cross Validation with function crossVal in package x12.

Usage

## S4 method for signature 'ts'
crossVal(object, x12Parameter, x12BaseInfo,
		showCI=FALSE, main="Cross Validation",
		col_original="black", col_fc="#2020ff", col_bc="#2020ff",
		col_ci="#d1d1ff", col_cishade="#d1d1ff",
		lty_original=1, lty_fc=2, lty_bc=2, lty_ci=1,
		lwd_original=1, lwd_fc=1, lwd_bc=1, lwd_ci=1, ytop=1,
		points_bc=FALSE, points_fc=FALSE, points_original=FALSE,
		showLine=TRUE, col_line="grey", lty_line=3,
		ylab="Value", xlab="Date",ylim=NULL,span=NULL)
## S4 method for signature 'x12Single'
crossVal(object, x12BaseInfo=new("x12BaseInfo"),
		showCI=FALSE, main="Cross Validation",
		col_original="black", col_fc="#2020ff", col_bc="#2020ff",
		col_ci="#d1d1ff", col_cishade="#d1d1ff",
		lty_original=1, lty_fc=2, lty_bc=2, lty_ci=1,

		showLine=TRUE, col_line="grey", lty_line=3,
		ylab="Value", xlab="Date",ylim=NULL,span=NULL)

Arguments

`object`	object of class `ts` or `x12Single-class`.
`x12Parameter`	object of class `x12Parameter`.
`x12BaseInfo`	object of class `x12BaseInfo`.
`showCI`	logical specifying if the prediction interval should be plotted.
`main`	plot title.
`col_original`	color of the original time series.
`col_fc`	color of the forecasts.
`col_bc`	color of the backcasts.
`col_ci`	color of the prediction interval.
`col_cishade`	color of the shading of the prediction interval.
`lty_original`	line type of the original time series.
`lty_fc`	line type of the forecasts.
`lty_bc`	line type of the backcasts.
`lty_ci`	line type of the prediction interval.
`lwd_original`	line width of the original time series.
`lwd_fc`	line width of the forecasts.
`lwd_bc`	line width of the backcasts.
`lwd_ci`	line width of the prediction interval.
`ytop`	multiplication factor for `ylim`.
`points_bc`	logical specifying if backcasts should additionally be indicated with points.
`points_fc`	logical specifying if forecasts should additionally be indicated with points.
`points_original`	logical specifying if the original time series should additionally be indicated with points.

`ylab`	label of y-axis.
`xlab`	label of x-axis.
`ylim`	range of the y-axis
`span`	vector of length 4, limiting the data used for the plot. Start and end date of said time interval can be specified by 4 integers in the format `c(start year, start seasonal period, end year, end seasonal period)`
