plot.proflik: Plots Profile Likelihoods

Description

This function produces plots of the profile likelihoods computed by the function proflik.

Usage

## S3 method for class 'proflik':
plot(x, pages = c("user", "one", "two"), uni.only, bi.only,
             type.bi = c("contour", "persp"), conf.int = c(0.90, 0.95),
             yaxis.lims = c("conf.int", "as.computed"),
             by.col = TRUE, log.scale = FALSE, use.splines = TRUE,
             par.mar.persp = c(0, 0, 0, 0), ask = FALSE, ...)

Arguments

x

an object of the class proflik, typically an output of the function proflik.

pages

specify how the plots will be arranged in the graphics device. The default option, "user", uses the current graphical parameters. The option "one" places all the profiles in the same page and the option "two"

uni.only

only 1-D profiles are plotted even if the object contains results about the 2-D profiles.

bi.only

only 2-D profile are plotted even if the object contains results about the 1-D profiles.

type.bi

Type of plot for the 2-D profiles. Options are "contour" for contour plot (the default) and "persp" for perspective plot.

conf.int

a vector with numbers in the interval $[0,1]$ specifying levels of the (approximated) confidence intervals. Defaults corresponds to the levels 90% and 95%.

yaxis.lims

defines the lower limits for the y-axis in the 1-D plots. If "conf.int" the limit is determined by the level of the confidence interval (the default) otherwise will be determined by the smallest computed value.

by.col

logical, If TRUE the plots are arranged by columns in a multiple graphics device.

log.scale

plots the x-axis in the logarithmic scale. Defaults to FALSE.

use.splines

logical. If TRUE (the default) the function spline is used to interpolate between the points computed by proflik.

par.mar.persp

graphical parameters to be used with persp plots. For more details see par.

ask

logical. Defines whether or not the user is prompted before each plot is produced.

...

additional arguments to be passed to the functions plot, contour and/or persp.

Value

• Produces plots with the profile likelihoods on the current graphics device. No values are returned.
