Function to overlay confidence intervals on the current plot.

Overlays confidence intervals on the current plot. Also draws a right hand axis, a horizontal broken line at zero, and marks the significant comparisons with an arrow, i.e. the CIs that do not intersect zero.

Usage

overlayCI(cis, xpos=NULL,ci.cols = NULL, ci.ex = 2, ci.ocol = "grey40", 
p.col = "grey40", pch = 1, sig.col = "red", sig.lwd = 1, yusr = NULL,
ci.label="Differences",ci.cex=0.5,arrow.length=0.1,...)

Arguments

cis

A matrix containing the confidence intervals. Each row corresponds to a different comparison, the first column is the estimated mean, and succesive pairs of columns give the lower and upper limits for different confidence levels.

ci.cols

A vector of colours, one colour for each confidence level. Defaults to shades of grey.

ci.ex

Controls confidence interval line width.

xpos

Horizonal positions where CIs are drawn. Defaults to 1.5,2.5,3.5,..

ci.ocol

Colour of zero line.

p.col

Colour of point used for CI centre.

pch

Symbol used for CI centre.

sig.col

Colour of arrow marking significant comparisons.

sig.lwd

Width of arrow marking significant comparisons.

yusr

Specifies the vertical par(usr) .Defaults to max and min.

ci.label

Label drawn on right margin.

ci.cex

Controls size of CI mean point symbol.

arrow.length

Controls size arrow at right hand axis.
