Problem about Rconsole: R for Windows Version 1.5.0 Patched (2002-06-05 and 2002-06-12)
R (Windows version) users/developers:
While I have checked R-help/-devel mailing lists and R-bug-tracking
system, this problem has not been reported so far. I would like to know
whether this problem is specific to my machine.
Lately I downloaded the version 1.5.0 patched [for windows] from

Rterm on Windows 2000 now works.
Guido has fixed Rterm hanging on Windows 2000 in interactive and --ess
modes. The problem was that 'PulseEvent' doesn't work under 2000 as
documented (and I can find nothing about this in MicroSoft's Knowledge
Base except that it is known to happen under a debugger).
The cross-compiled pre-release at http://www.stats.ox.ac.uk/pub/bdr/RWin/Rpre

R-patched for Windows
I've put up a build of the current R-patched (and updated recommended
packages) for Windows at
http://www.stats.ox.ac.uk/pub/bdr/RWin/Rpre/SetupRpatched.exe
This should be able to rename files on Win 9x (unlike the mid-May build)
and can build packages accessing Rblas.dll.
As ever, this is less tested than an official release, in particular only
on Windows XP, but ought to have fewer

Manova and specifying the model
Hi,
I would like to conduct a MANOVA. I know that there 's the manova() funciton and the summary.manova() function to get the appropriate summary of test statistics.
I just don't manage to specify my model in the manova() call. How to specify a model with multiple responses and one explanatory factor?
If I type:

MANOVA usage
Hello,
I had a couple questions about manova modeling in R.
I have calculated a manova model, and generated a summary.manova output
using both the Wilks test and Pillai test.
The output is essentially the same, except that the Wilks lambda = 1 -
Pillai. Is this normal? (The output from both is appended below.)
My other question is about the use of MANOVA. If I have one variable which

R 1.1.0 going into feature freeze
The planned release of R 1.1.0 will be next Thursday. The development
version is going into feature freeze tomorrow, meaning that we'll only
do testing and fix simple bugs during the next week.
Those of you who prefer to find bugs before releases instead of
afterwards may want to try it out and tell us what crawls out.

Link on R-help doesn't work
Hi there,
I found a small problem after installing the recent version
of R (1.5.0) for Windows. The link on its documentation (.PDF)
does not work. Am I just the one who has this problem ?
I am using Windows ME.
Thank you.

Rcmd ?
Hi,
I tried running Rcmd.exe to no avail. It doesn't even start because it tries
to read some memory address that NT says it can't and terminate.
I tried downloading and reinstalling rw1020sp.zip with the installer twice
just in case it got corrupted somehow in transport but it resulted in the
same problem.
What should I do?

Repeated Measures MANOVA in R
Can R do a repeated measures MANOVA and tell what dimensionality the statistical variance occupies?
I have been using MATLAB and SPSS to do my statistics. MATLAB can do ANOVAs and MANOVAs. When it performs a MANOVA, it returns a
parameter d that estimates the dimensionality in which the means lie. It also returns a vector of p-values, where each p_n tests
the null hypothesis that the mean

MANOVA: how do I read off within and between Sum-of-Squares info from the manova result?
Hi all,
I am experimenting the function "manova" in R.
I tried it on a few data sets, but I did not understand the result:
I used "summary(manova_result)"
and "summary(manova_result, test='Wilks')"
and they gave a bunch of numbers...
But I need the Sum-of-Squares of BETWEEN and WITHIN matrices...
How do I read off from the R's manova results?

summary.manova and rank deficiency

I have received the following error from summary.manova:

The data is simulated data for 64 variables. The design is a 2*2 factorial with 10 replicates per treatment. Looking at the code for summary.manova, the error involves a problem with qr(). Does anyone have a suggestion as to how to

I had a question wrt the car package. How do I evaluate whether a

Standard deviation from MANOVA??
Hi,
I have problem getting the standard deviation from the manova output.
I have used the manova function: myfit <- manova(cbind(y1, y2) ~ x1

I tried to get the predicted values and their standard deviation by using:
predict(myfit, type="response", se.fit=TRUE)
But the problem is that I don't get the standard deviation values, I only

extracting elements from print object of Manova()
Hi there,
Does anyone know how to extract elements from the table returned by Manova()?
Using the univariate equivalent, Anova(), it's easy:
a.an<-Anova(lm(y~x1*x2))
a.an$F
This will return a vector of the F-values in order of the terms of the model.
However, a similar application using Manova():
m.an<-Manova(lm(Y~x1~x2))
m.an$F
Returns NULL. So does any attempt at calling the

Stepwise Manova
Hello all,
I have a question on manova in R:
I'm using the function "manova()" from the stats package.
Is there anything like a stepwise (backward or forward) manova in R (like there is for regression and anova).
When I enter:
step(Model1, data=Mydata)
R returns the message:
Error in drop1.mlm(fit, scope$drop, scale = scale, trace = trace, k = k, :
