unequally spaced factor levels orthogonal polynomial contrasts coefficients trend analysis
...age where you can do ANOVA based trend analysis on grouped data

Beginner: Homogenity of Variances
Hello,
for my meta-analysis I try to test if two varainces are equal without
using the raw scores. I have is the SD's, N's and the Means.
I want to test the variances from dependent and independend
samples.
I assume I can use the var.test procedure for the independent
samples, but what about the dependent samples ? Has anyone an
idea how to realise this with R ?
Thanks in advance

ANOVA procedure on the sufficient statistics
Hi,
I have a two-way anova with unequal cell numbers that I want to analyze.
The problem is I don't have individual observations of the data.
I only have the sufficient statistics (mean, variance, # of observations) for each cell.
Is there any existing function in S-plus that would allow me to do aov() with the sufficient statistics?
The table is like
G1 G2 G3 G5 G6
T1
T2
T3

candisc plotting
Hello,
I have a file with two dependent variables (three and five) and one
independent variable. I do i.mod <- lm(cbind(three, five) ~ species,
data=i.txt) and get the following output:
Coefficients:
three five
(Intercept) 9.949 9.586
species -1.166 -1.156
I do a" i.can<-candisc(i.mod,data=i):
and get the following output:

Flipping a heatmap
Hi
I am using the heatmap function in package mva to look at large
correlation matrices visually.
Is there any way to "flip" the output of heatmap plot left-right so
that, if presented with a correlation matrix, it plots the unity
elements in the correlation matrix along a diagonal from top left to
bottom right?
For example:
library(mva)
x = matrix(rnorm(1000), ncol=10)
z = cor(x)

(Meta-analysis) How to build|fake a [n]lm[e] object ?
Dear all,
I recently had to review the current litterature about some medical treatment
with two possible variants (let's call them A and B). I collected all available
prospective randomized trials about this treatment : I got four trials for the
A variant and three for the B variant, all studies comparing one variant to a
"suitably choosen" placebo.
Two classes of variables are of
