Unbalanced Manova
Dear all,
I need to do a Manova but I have an unbalanced design. I have
morphological measurements similar to the iris dataset, but I don't have
the same number of measurements for all species. Does anyone know a
procedure to do Manova with this kind of input in R?
Thank you very much,
Naiara.

reading contigency tables
Hi all,
I need some help using read.ftable to read a contingency table. My columns
are organized as follows:
order--family--species--location--number of individuals
I couldn't figure out how to change the data on my text file to be
imported into R; and after you do that, is it possible to convert the
table into a data frame? Any tips would be greatly appreciatted!
Thanks a lot,
Naiara.

polr (MASS)
Hello all,
I am trying to use polr (the ordered logistic model from MASS) but I am
getting the following error message:
Error in if (all(pr > 0)) -sum(wt * log(pr)) else Inf :

My response variable is a factor with 3 levels and I have 2 independent
variables. I am not sure if I guessed the starting parameters right, which

Rcmdr and scatter3d
Hi folks,
I'd like to use scatter3d (which is in R commander) to plot more than one
dataset in the same graph, each dataset with a different color. The kind
of stuff you would do with "holdon" in Matlab.
I read a recent message that was posted to this list with a similar
problem, but I couldn't understand the reply. Could someone give me one
example? How do you plot subgroups

Random forests
Dear all,
I would like to use a tree regression method to analyze my dataset. I
am interested in the fact that random forests creates in-bag and
out-of-bag datasets, but I also need an estimate of support for each
split. That seems hard to do in random forests since each tree is
grown using a subset of the predictor variables.
I was thinking of setting mtry = number of predictor variables,

random forest regression
Dear all,
I am doing a regression in ramdomForest, using the option "sampsize" reduce
the number of records used to produce the randomForest object.
The manual says "For classification, if sampsize is a vector of the length
the number of strata, then sampling is stratified by strata, and the
elements of sampsize indicate the numbers to be drawn from the strata". I

sampsize in Random Forests
Hi all,
I have a dataset where each point is assigned to a class A, B, C, or
D. Each point is also assigned to a study site. Each study site is
coded with a number ranging between 1-100. This information is stored
in the vector studySites.
I want to run randomForests using stratified sampling, so I chose the option
strata = factor(studySites)
But I am not sure how to control the number of

Congratulations to the Centos Team for the hard work on Centos 6
I just wanted to say Congratulations and thank you to the Centos Team for
all of the work on Centos 6 - I know the last few months have not been easy
- but the real benefit will be that Centos 6 will be as good and as stable
as Centos 5 has been for me and everyone who has been using it for the past
4 years. It has never a matter of just getting it done - but getting it
done right.
Thank You

Dear List,
My 'puter runs SuSE Linux version 8.0

But, a segmentation faults prevents me from starting Wine :-(
Please, is there a remedy to fix this ?

Installing rails without gems
After reading the article about rails in OnLamp, I''ve decided to give it a try.
In many way it resembles a product that I used to work several years ago,
but based on Tcl. So I this might just be what a Pythonier as me needs
to try out Ruby. :)
Now the problem is, right now the computer where I want to play around
with rails doesn''t have net access. I already downloaded the

No automatic refresh?
Hi!
I've been struggling with this install of Samba 2.0.4b on Linux/x86 2.0.36.
All of the client machines run Windows NT 4, SP 3.
I'm exporting /tmp as pub, and if I right click in the folder and create
a new folder, it doesn't show up until I go to 'view' and 'refresh'.
If I delete something, it doesn't go away until I refresh.
Why?
