ciplot.corregp: Plotting Confidence Intervals for Correspondence Regression

In corregp: Functions and Methods for Correspondence Regression

Description

Method to plot confidence intervals for coordinates in correspondence regression.

Usage

## S3 method for class 'corregp'
ciplot(x, parm = "x", axis, cl = 0.95, nq = TRUE,
  horiz = FALSE, na.rm = FALSE, type = "p", col = "darkgrey",
  cex = par("cex"), font = par("font"), family = par("family"),
  alim = NULL, adir = 1, ecol = "darkgrey", ewid = par("lwd"),
  etyp = par("lty"), psym = 16, pcol = par("col"), pcex = cex,
  pbgc = par("bg"), lwd = ewid, lty = etyp, sfrac = 0.01, gap = 0,
  main = NULL, sub = NULL, ...)

ciplot(x, ...)

Arguments

x	The output of a call to corregp (i.e. an object of class "corregp").
parm	The parameter for which to plot the confidence intervals. Can be either "y", "x", or any vector of term names in X, level names in X or level names in Y. Defaults to "x".
axis	The axis for which to plot the confidence intervals.
cl	The confidence level for the confidence intervals. Defaults to 0.95.
nq	Logical specifying whether to use a normal quantile (i.e. apply qnorm) in the computation of the confidence intervals. Defaults to TRUE. If FALSE, then the confidence intervals are computed directly with the quantile function.
horiz	Logical specifying whether the confidence intervals should be plotted horizontally or not. Defaults to FALSE.
na.rm	Logical specifying whether to omit NA coordinates from the plot. Defaults to FALSE.
type	The type of plot: see plot.default. For correspondence regression, there is an additional option "labs" which plots the text labels at the centers of the confidence intervals. Defaults to "p".
col	Color of the text labels: either numeric or see colors.
cex	Character expansion factor: a number to specify the size of the text labels.
font	Font of the text labels: 1 for plain, 2 for bold, 3 for italic, and 4 for bold italic. Defaults to 1.
family	Font family of the text labels: can be "serif", "sans", "mono" or one of the Hershey fonts.
alim	Vector of two values specifying the lower and upper limit between which to plot the axis.
adir	Reading direction of the text labels on the (horizontal) axis: either a numeric value between 0 and 3 (see the las argument in the graphical parameters par) or a character value matching either "horizontal" or "vertical". Defaults to 1 (horizontal).
ecol	Color of the error bars: either numeric or see colors.
ewid	Width of the error bars: a number to specify the line width.
etyp	Line type of the error bars: 0 or "blank", 1 or "solid", 2 or "dashed", 3 or "dotted", 4 or "dotdash", 5 or "longdash", 6 or "twodash". Defaults to 1.
psym	The symbol (or "plotting character") to use for the centers of the confidence intervals.
pcol	Color of the center symbol: either numeric or see colors.
pcex	Character expansion factor of the center symbol.
pbgc	Background color of the center symbol: either numeric or see colors.
lwd	Width of all lines except for the error bars, e.g. the connecting lines: a number to specify the line width.
lty	Line type of all lines except for the error bars, e.g. the connecting lines: 0 or "blank", 1 or "solid", 2 or "dashed", 3 or "dotted", 4 or "dotdash", 5 or "longdash", 6 or "twodash". Defaults to 1.
sfrac	Width of "crossbar" at the end of error bar as a fraction of the x plotting region. Defaults to 0.01.
gap	Space left between the center of the error bar and the lines marking the error bar in units of the height (width) of the letter "O". Defaults to 0.
main	The main title of the plot.
sub	The subtitle of the plot.
...	Further arguments passed to or from other methods.

Details

ciplot (of a corregp output) makes use of plotCI from the package gplots.

Value

A plot window containing the confidence intervals.

Examples

data(HairEye)
haireye.crg <- corregp(Eye ~ Hair * Sex, data = HairEye, b = 3000)
ciplot(haireye.crg, parm = "y", axis = 1)
ciplot(haireye.crg, parm = c("Hair", "Sex"), axis = 1)
