Different generic functions for classes JOC and JOCMV

Description

Generic functions for summarising and plotting objects of class JOC or JOCMV.

Usage

## S3 method for class 'JOC'
plot(x, equi=log(c(0.8, 1.25)), axnames=NULL, main=NULL, xlim=log(c(0.77, 1.3)),
     ylim=log(c(0.77, 1.3)), col="black", convexify=FALSE, ...)

## S3 method for class 'JOC'
print(x, digits=max(3, getOption("digits") - 4), ...)

## S3 method for class 'JOC'
summary(object, digits=max(3, getOption("digits") - 4), ...)

## S3 method for class 'JOCMV'
plot(x, axnames=NULL, main=NULL, xlim=NULL, ylim=NULL, col="black", ...)

## S3 method for class 'JOCMV'
print(x, digits=max(3, getOption("digits") - 4), ...)

## S3 method for class 'JOCMV'
summary(object, digits=max(3, getOption("digits") - 4), ...)

Arguments

x

An output object of class JOC or JOCMV.

object

An output object of class JOC or JOCMV.

digits

A numeric value giving the number of significant digits to be printed.

equi

A numeric vector of length 2 specifying the equivalence region (lower and upper equivalence threshold) to be shaded in grey. When set to NULL no equivalence region is drawn. Default is log(c(0.8, 1.25)).

axnames

A vector of two character strings giving the x and y axis labels. For plot.JOC, when set to NULL the column names of dat are used as axis labels. Default is NULL.

main

A character string giving the plot title. Default is NULL.

xlim

A numeric vector of length two specifying the plotting range on the x-axis. Default is log(c(0.77, 1.3)) for plot.JOC and NULL for plot.JOCMV.

ylim

A numeric vector of length two specifying the plotting range on the y-axis. Default is log(c(0.77, 1.3)) for plot.JOC and NULL for plot.JOCMV.

col

A character string specifying the colour of the plotted region or intervals.

convexify

A logical specifying whether the convex hull around a non-convex region should be plotted instead of the region itself. Ignored unless method="limacon.fin" or method="limacon.asy" for the JOC object. Default is FALSE.

...

Further plotting arguments to be passed to methods. Type ?plot for details.

Details

print and summary summarise the estimates and confidence set boundaries of an object of class JOC or JOCMV that was created with cset or csetMV, respectively. plot displays a (simultaneous) confidence region or intervals when applied to an object of class JOC or JOCMV.

Value

An on-screen summary or graphical display.

Note

Warning: please use with care! Some of the functionality has not yet been thoroughly tested.

Examples

## Not run: 
# Example 1: simultaneous 90% confidence region for bivariate data

bivar <- mvtnorm::rmvnorm(n=100, mean=rep(0.05, 2), sigma=diag(2) * 0.05)

hotelling <- cset(dat=bivar, method="hotelling", alpha=0.1)
summary(hotelling)
plot(hotelling, main="90% Hotelling Region")

# Example 2: simultaneous 90% confidence region for the mean and variance of univariate normal data

univar <- rnorm(n=50)

moodvar <- csetMV(dat=univar, method="mood", alpha=0.1, scale="var")
summary(moodvar)
plot(moodvar, main="90% Mood Region")
