manova
I am using rw0641 with Windows 98. In the help for aov it states that the
formula can sepecify multiple responses for a "maov". The help doesn't give
an example, Venables and Ripley 1997:381 doesn't either. It isn't mentioned
in the scripts nor in the section R Complements nor in Rnotes. I tried
aov(c(y1,y2,y3)~x)
which seemed reasonable to me but doesn't work. How

lme
I am using rw0641.
In my continuing quest to understand repeated measures analysis, I again
return to lme. I exported the Potthoff and Roy data Orthodont.dat from
S-PLUS 4.5 to avoid capture errors and ran the examples in the R help. I
imported the data.frame with
data <- read.table("Orthodont.dat",header=T)
attach(data)
and created the objects

Influence.measures
I am using rw0641 with Windows 98. To list just the influential
repetitiones that result from "influence.measures", I am using the input
result <- lm(y~x)
and the code from the example in the help for "influence.measures"
INFLM <- function(result){
inflm <- influence.measures(result)
which(apply(inflm$is.inf,1,any))
}
It works fine up to now with the

for loops and counters
I am trying to assign values to a vector (pvalue). Similar code works in C
but not in R. What am I doing wrong?
r <- pvalue <- 0
for(i in (1:(k-1))){
for(j in (i+1):k){
r <- r+1
tstat <- (means[i]-means[j])/rms
pvalue[r] <- 2*(1-pt(abs(tstat),df))
}
}
Thank you.

vector of NA indices
I have a vector Pes with 600 elements some of which are NA's. How can I
form a vector of the indices of the NA's.
for(i in 1:600) if(is.na(Pes[i])) print(i)
prints the indices of the NA's but I can't figure out how to put the
results in a vector.
Thank you very much.

How to cite
I am updating my lab manual in Spanish. How should I cite your supplements
to Venables and Ripley 1997 and the scripts.
Thank you very much

postscript()
I am using RedHat 6.1, the R1.1.0 binary download, and an HP Deskjet 692C.
For some time I have been trying unsuccessfully to integrate R postscript
graphics in LaTex. I consulted the Bug Tracking System.
In the preamble of the LaTex file (test.tex) I have placed the line
\usepackage{graphicx,color}
and I use

Tukey.aov with split-plot designs
I am using R 1.1 with Redhat 6.2 and RW 1.001 with Win98 (the upkey doesn't
work on my IBM either as has been previously reported by others).
The function aov doesn't return either the residuals or the residual
degrees of freedom for split-plot designs.

How to superimpose a histogram and density plot
NCSS has a nice plot of the histogram and density plot superimposed. The
S-PLUS 4 Guide to Statistics on page 45 suggests the following code for a
general purpose density plot for a vector named data
iqd <- summary(data)[5]-summary(data)[2]
plot(density(data,width=2*iqd),xlab="x",ylab="",type="l")
Is it possible to superimpose the density plot on a histogram

rwinst + metafile + gif
1) rwinst
Brian Ripley has provided me a new version of 'rwinst.exe' which
should solve the signaled problem (installing in the root of the hard-disk).
It should be available tomorrow from Wien (and in few days from the other
mirrors).
2) gif
There was some problems in rw0641. It used to work before and it should
work again in rw0642 (at least, it does on my system). So, please,

ESRI shapes --again
thanks to all the help so far I have code now that works on windows
(albeit very clunky) that can read the pertinent info from the shape header
and return a list with all the necessary parameters to read info out of
the shape file. Now come the big design questions

hold the info from the shape file and a data frame as part of

Packages under windows
I just downloaded the NT version of R and cannot
find anything concrete on loading packages.
There is alot on how to do it under Unix.
The windows FAQ briefly mentions it but
does not explain it.
I have donwloaded windows binaries of the package
"clust.zip" and unzipped it into my

directory... So I have

Using rw0642 under win95, on executing from a directory on the c: drive:

there is a whirring from drive a: (empty), then the message appears in a

Repeating the command a few times finally results in success with no

covariance matrix of the regression coefficients
Greetings,
Cohen, Cohen, West, and Aiken 2003 (Applied Multiple Regression-Correlation
Analysis for the Behavioral Sciences, Third Edition) on page 273 state the
covariance matrix of the regression coefficients is provided by standard
programs for multiple regression, including SAS, SPSS, and SYSTAT. How can
it be calculated with R. Thank you very much.
