Plot absolute and relative information

Description

Plot absolute and relative information of influence curves.

Usage

infoPlot(object,  ...)
## S4 method for signature 'IC':
infoPlot(object, ..., withSweave = getdistrOption("withSweave"), 
             colI = grey(0.5), lwdI = 0.7*par("lwd"),
             main = FALSE, inner = TRUE, sub = FALSE, 
             col.inner = par("col.main"), cex.inner = 0.8, 
             bmar = par("mar")[1], tmar = par("mar")[3],
             mfColRow = TRUE)

Arguments

object object of class "InfluenceCurve"
withSweave logical: if TRUE (for working with Sweave) no extra device is opened
main logical: is a main title to be used? or
just as argument main in plot.default.
inner logical: panels have their own titles? or
character vector of / cast to length number of comparands: main in plot.default)
sub logical: is a sub-title to be used? or
just as argument sub in plot.default.
tmar top margin – useful for non-standard main title sizes
bmar bottom margin – useful for non-standard sub title sizes
colI color of the classically optimal IC
lwdI linewidth of the classically optimal IC
cex.inner magnification to be used for inner titles relative to the current setting of cex; as in par
col.inner character or integer code; color for the inner title
mfColRow shall default partition in panels be used — defaults to TRUE
... further parameters for plot

Details

Absolute information is defined as the square of the length of an IC. The relative information is defined as the absolute information of one component with respect to the absolute information of the whole IC; confer Section 8.1 of Kohl (2005).

Any parameters of plot.default may be passed on to this particular plot method.

For main-, inner, and subtitles given as arguments main, inner, and sub, top and bottom margins are enlarged to 5 resp. 6 by default but may also be specified by tmar / bmar arguments. If main / inner / sub are logical then if the respective argument is FALSE nothing is done/plotted, but if it is TRUE, we use a default main title taking up the calling arguments in case of main, default inner titles taking up the class and (named) parameter slots of arguments in case of inner, and a "generated on <data>"-tag in case of sub. Of course, if main / inner / sub are character, this is used for the title; in case of inner it is then checked whether it has correct length. In all title arguments, the following patterns are substituted:
