Using postfix in CentOS 6 to relay mails to First.Last@gmail.com
Hello fellow CentOS users,
I'm using:

I own several domains and would like all
incoming mails addressing those domains
to be forwarded to my Gmail address.

isoMDS and dist
I am starting with a matrix in which rows are vegetation plots and
columns are various characteristics including ID# and elevation. I
removed elevation and ID columns to avoid having those characteristics
influence the distances between points which I calculated using the
"dist" command. The resulting distance file was then used in isoMDS.
What I want to know is whether I can

Use postfix and spamd on CentOS 6 - looking for a shortest guide
Hello fellow CentOS-users,
on the net there are lots of Spamassassin related HOWTOs - describing how
to create a shell script for Postfix and how to install Spamassassin and
start its spamd daemon - step by step. Additionally antivirus setups are
described...
But I have a strong feeling, that this is unneeded on CentOS 6 - because
there are already preconfigured stock packages for postfix and

Trying to install rjags on Mac OS X 10.5
Greetings,
I wonder if anyone can offer any help or advice--even direction to an
appropriate source of advice. I am trying to install rjags 1.0.1 on Mac OS X
10.5 (see http://www-fis.iarc.fr/~martyn/software/jags/). I have R.app 2.6.1
installed.
JAGS 1.0.1 is apparently successfully installed. I (think I) know this because

Dear UseRs,
Apologies, I tried to post to the list yeasterday, but (for some

I am having some problems using R with WinBUGS using the R2WinBUGS

isoMDS
Dear List:
I have a question regarding an MDS procedure that I am accustomed to
using. I have searched around the archives a bit and the help doc and
still need a little assistance. The package isoMDS is what I need to
perform the non-metric scaling, but I am working with similarity
matrices, not dissimilarities. The question may end up being resolved
simply.

isoMDS and 0 distances
Hi,
I'm trying to do a non-metric multidimensional scaling using isoMDS.
However, I have some '0' distances in my data, and I'm not sure how to
deal with them. I'd rather not drop rows from the original data, as I am
comparing several datasets (morphology and molecular data) for the same
individuals, and it's interesting to see how much morphological
variation can be

isoMDS vs. other non-metric non-R routines
Dear useRs,
last week I asked you about a problem related to isoMDS. It turned
out that in my case isoMDS was trapped. Nonetheless, I still have
some problems with other data sets. Therefore I would like to know if
anyone here has experience with how well isoMDS performs in
comparison to other non-metric MDS routines, like Minissa.
I have the feeling that for large data sets with a high

Stress with MDS
Hi,
I am looking for the best multidimensional configuration for my data (47*47
distance matrix).
I ve tried classical metric (cmdscale) and non metric MDS (isoMDS, nmds)
but it is now difficult to choose the best solution because of the
uncertainties in the definitions of the "stress" function.
So, same problem, several questions :

Beginners Question
Dear all,
I'm completely new to R and at first I must say that it is a great program!
But I have a problem with the function isoMDS from the MASS package. I
have this code which I load with source() from a file:
x <- c(163.59514923926784, 150.01448475257115, ...... {here are some
more values})
x.sort <- sort(x)
x.dist <- dist(x.sort)

x.mds <- isoMDS(x.dist)

limit of cmdscale function

We have a few questions regarding the use of the "isoMDS" function.
When we run "isoMDS" function using 60,000 x 60,000 data matrix,
we get the following error message:

MASS: isoMDS and sammon
If tbl is an object of class 'dist', you can do this:
a <- sammon(tbl, k=3)
But you can't do this:
b <- isoMDS(tbl, k=3)
Wouldn't it be sensible to have identical interfaces to sammon()
and isoMDS() ?
I think all that would be needed is to change this:
isoMDS <- function(d, y=cmdscale(d, 2), maxit=50, trace=TRUE)

MDS with missing data?
Hello
I will be applying MDS (actually Isomap) to make a
psychological
"concept map" of the similarities between N concepts.
I would like to scale to a large number of concepts,
however, the
resulting N*(N-1) pairwise similarities is prohibitive
for a user survey.
I'm thinking of giving people random subsets of the
pairwise
similarities.
Does anyone have recommendations for this

Size of type double in object type dist (PR#1255)
The following problem occurs in R 1.4.0 and 1.3.1 for Windows95,
but not in R 1.2.0 for Windows95.
The problem does not occur in R 1.4.0 for Linux PC, Linux Alpha
and HP-UX.
Sometimes, the type of 'Size' of an object of type 'dist'
changes from integer into double. Running cmdscale on such a
'dist' object gives invalid results.

about isoMDS method
Hi,
For example:
I built a half matrix "w" using a daisy(x, metric = c("euclidean"))

And next I transformed this matrix "w" using isoMDS function, for example
isoMDS(w, k=2) and as result I got:

And now I have two questions:
