Convert ftable to latex?
Dear list,
I cannot make the latex command to output a ftable objet the way I
want it. Is it posible?
I found a post in the archives saying that one should use the rgroup
and n.rgroup arguments to supply the row names, but so far I have been
unsuccessful.
This is what I have:

Incoming calls from Andrews & Arnold failing to authenticate
I have service with both VoIPtalk.org and Andrews & Arnold (aa.net.uk).
VoIPtalk calls are unauthenticated and reach me fine, but Andrews &
Arnold calls are authenticated. The last call I successfully received
was on Tuesday afternoon. Initially, A&A were for some odd reason not
sending calls to my server, but that has been resolved. The problem now
is that the calls fail to

Use voice onset timing to identify voiceless
In increasing the computation time and bit rate with VBR:
Has anyone considered implementing the standard audiological
recognition technique of using the duration of zero energy (voice
onset timing) to identify the presence of voiceless sounds?
I would like a means of determining whether or not a given window will
be full of voiced speech or not.

smbclient gives strange results
Hello,
I've been using Samba on a Sun server but we recently discontinued using the
Sun and switched to using Samba on a RH linux server. I can't get file
sharing to work on the new server. When I test the connection to the samba
server (velar) by running smbclient //velar/homes -U eric I get an error

How to compute Wilk's Lambda
Dear helpeRs,
the following data set comes from Johnson/Wichern: Applied Multivariate
Statistical Analysis, 6th ed, pp. 304-306.
/X <- structure(c(9, 6, 9, 3, 2, 7), .Dim = as.integer(c(3, 2)))
Y <- structure(c(0, 2, 4, 0), .Dim = as.integer(c(2, 2)))
Z <- structure(c(3, 1, 2, 8, 9, 7), .Dim = as.integer(c(3, 2)))/
I would like to compute Wilk's Lambda in R, which I know is 0.0385.

spelling with <g>?
Hello,
What should the following input produce?
Dutch has shifted Germanic g to the velar fricatives [?] and [x], but
retained the spelling with <g> and thus at least a visual similarity
to German; English and Frisian have shifted g to [j] before palatal
vowels
The Dingus says:

evaluation of discriminant functions+multivariate homoscedasticity
Hello,
I am switching from SPSS-Windows to R-Linux. My university is very
SPSS-oriented so maybe that's the cause of my problems. I am a beginner
in R and my assignments are SPSS-oriented, so I hope I don't annoy
anyone with my questions...
Right now I've got 2 problems:
-I have to evaluate discriminant functions I have calculated with
lda(MASS). I can't find a measure that

Thank you!
Thank you very much for your help, your fuction runs on R without
any change, and the results are the same that your obtain with Splus,
but there still a small difference.
In SAS
W=0.960439
With your shapiro.wilk.test
W=0.9606107
But the p-values are almost the same.
Thank you very much for your help.

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

Built-In Wilks Lambda for lda?
Hello,
using the lda-method from MASS-package I was wondering whether there is
a built-in method for figuring out Wilks' Lambda?
Searching the Web I found in the r-help archive a thread form june 2002,
but it didn't help me.
I understand I can use manova and its summary-method to get Wilks' Lambda
on the screen, but I don't see the connection to lda from MASS.

Animal Morphology: Deriving Classification Equation with Linear Discriminat Analysis (lda)
Fellow R Users:
I'm not extremely familiar with lda or R programming, but a recent editorial
review of a manuscript submission has prompted a crash cousre. I am on this
forum hoping I could solicit some much needed advice for deriving a
classification equation.
I have used three basic measurements in lda to predict two groups: male and
female. I have a working model, low Wilk's lambda,

discriminant analysis
Hello,
I have run a discriminant analysis (with lda() from the MASS package)
but I can't find a way to examine the p-values for the discriminant
functions. I would like to calculate a Wilk's lambda and then the
Bartlett's V statistic which is distributed as a chi squared and test
its significance, but I haven't found out how to do so. Can anyone help?
Thank you,

multivariate F distribution
Dear List,
Is there any function in R to generate multivariate F distribution with
given correlation/covariance matrix?
Actually, I just want to generate some 2-dimentional non-normal data
sets (skewed) for low (may be around 0.3 cor coeff.) negatively and also
positively correlated variables ?
Thanks in advance.

MANOVA / Hotelling's Test
Hi everybody ...
I have to perform Hotteling's T^2 Test - more generally a MANOVA - on a
set of data. Is there a (simple?) possibility to do it in R?
The somewhat obvious way to do it would be
> summary(aov(Y ~ x1 + x2 ... + xn))
where Y would be a two-column matrix.
But this does not work in any possible combination of matrix or factor
dimensions! Is it principally not possible
