Convert a List of Distances to a Distance Matrix
Hello,
Is there an easy function for switching list to matrix. My list is of
genetic distances between species pairs:
A A 0
A B .5
A C .25
B C .5
and I want a distance matrix such as:
A B C
A 0 .5 .25
B .5 0 .5
C .25 .5 0
for use in a mantel test.
Thank you for the help!
cheers,
charlie

Writing GLM/GEE Ouput to Text File
Hello,
How can one write the output of a GLM/GEE model to a text file, such that
the results appear in text file in the same (or similar) format they appear
in the R console? For instance, I have the following model:
Traitresult <- compar.gee(Y~X, data = data, family = "binomial", phy = tree,
scale.fix = TRUE, scale.value = 1)
How would I write "Traitresult" to a text

Matrix Row name Compatibility
Hello,
I am trying to preform a comparative analysis using the partial mantel
method. However, i am having trouble creating compatible matrices. I can
create matrices from my numerical data using the 'distance(x, method)'
function from ecodist, but the row/column names are out put as numbers.
While when i create a phyo-distance matrix using 'cophenetic(x)' from APE,

COMPAR.GEE Output
Hello,
I am running the program COMPAR.GEE within the package APE. My dependent
variable is binomial, while my independent variable is a multi-state
categorical variable. The output reports an estimate for each state of the
independent variable except the first one. For example, for the variable X
with 3 states, the output is:
intercept (estimate)
X2 (estimate)
X3 (estimate)

COMPAR.GEE error with logistic model
Hello,
I am trying to run the APE program COMPAR.GEE with a model containing a
categorical response variable and a mixture of continuous and categorical
independent variables. The model runs when I have categorical (binary)
response and two continuous independent variables (VAR1 and VAR2), but when
I include a categorical (binary) independent variable (VAR3), I receive the
following output with

Odds ratios for categorical variable
Dear R-users:
How does one calculate in R the odds ratios for a CATEGORICAL predictor
variable that has 4 levels. I see r-help inquiries regarding odds ratios
for what looked like a continuous predictor variable. I was wondering how
to get the pairwise odds ratios for comparisons of levels of a categorical
predictor variable. I can't seem to get the correct output using:

Bootstrap direction
Hi all,
I am trying to bootstrap a small data set into 1000 "pseudodatasets" and
then run an ANOVA on each one. Can anyone provide guidance on how I could
do this?
Thank you.

Threshold vector error correction models
Hi,
is anyone aware of estimation functions for threshold vector error correction / threshold cointegration models?
I didn't find anything for R using RSeek or Google.
Thanks a lot for any pointers,

Pseudodataset text file
Hi All,
Two weeks ago, I received instructions from the R list about creating
pseudodatasets by bootstrapping an existing dataset 1000 times. I received
code that bootstrapped my dataset and ran an ANOVA on each pseudodataset,
producing a histogram of F-values. Here is the code I received that
produces this F-histogram.
X <- data.frame(b=rnorm(2162),c =factor(rep(1:47,each=46)))

Dual personality samba server
Dear All,
I've just installed Samba version 1.9.18p10 on one of our HP-UX boxes.

I've been playing with the idea of changing the behaviour of the server
based on what the client calls it. What I'd like to do is have samba do

sort of fread to read from a file at fixed positions?
Hello everybody,
I need to read a file with a header (EDF files, recorded
electroencephalogram signals) that has fixed byte positions for each
field of its header.
These fields have no separator between them, for example:
<8 ascii name of the patient><10ascii start time of the recording><4

I read that perfectly in Octave by using fread, fseek and other

Some ideas
Hi all,
I'll try to explain my suggestion with my poor english.
I've got the feeling that icecast is full of potential but not growing
as fast as it can or simply not having the support it could have.
The greatest lack are the "open doors" for new coders, webdesigners,
translators, etc. Icecast is open: the sourcecode is open, the mailing

color.ramp in maptools

I am trying to use the maptools library to display geographical data. At

Looking at the plot.Map function itself, I see that it calls a
