bagplot()
Hello,
I saw a little discussion about this in the archives, but it was unclear to me whether someone had
submitted a port to R of the Splus bagplot() function. If so, does anyone know where I could get
it? Thanks.
Best,

Error when using Bagplot function
Hi, I am using the bagplot function within the aplpack package and often get
this error:
Error in chull(pg[, 1], pg[, 2]) :
NA/NaN/Inf in foreign function call (arg 2)
Here's an example of data for which this happens:
bagplot(c(-4.66, -2.62, -3.65 ,-3.07 ,-4.91, -4.56 ,-3.79, -3.10, -3.01),
c(2.14, -7.18, -0.15 , 2.67, -2.49, -0.89 , 0.96 , 0.59, -4.59))
Can anyone help?

money data types
What data type is best for storing currency? I''m trying to come up
with a reliable cross-database solution for rails that is not too
complicated. Since I''m going to have currency fields all over the
place, I''m not so sure that using two integer fields for each amount
would qualify as uncomplicated. I''d like to be able to use database

"continuous" boxplot?
I have two vectors x and y, which I would like to plot against each
other. I am also displaying other data in this plot. However, I have
about 1 million points to plot, and just plotting them x againt y is
not very informative. What I'd like to do is to do sort of a
continuous box plot.
My x values goes from -1 to 1 and my y values from 0 to 1, so I?d like
to plot the median and quantiles,

Centos backup tools
Hi all!
I'm building a raid box to use for backups, connectivity will be either
USB3 or esata.
Looking for suggestions on backup software I can use.
I know there's rsync, which may be a good solution. I also find backupPC
at epel, backintime also at epel, kbackup.
DejaDup looks interesting, but none of the repos I'm set up to use
shows it being available.

Results of MCD estimators in MASS and rrcov
Hi!
I tested two different implementations of the robust MCD estimator:
cov.mcd from the MASS package and
covMcd from the rrcov package.
Tests were done on the hbk dataset included in the rrcov package.
Unfortunately I get quite differing results -- so the question is whether
this differences are justified or an error on my side or a bug?
Here is, what I did:

Ellipse that Contains 95% of the Observed Data
I can take the results of a simulation with one random variable and generate
an empirical interval that contains 95% of the observations, e.g.,
x <- rnorm(10000)
quantile(x,probs=c(0.025,0.975))
Is there an R function that can take the results from two random variables
and generate an empirical ellipse that contains 95% of the observations,
e.g.,
x <- rnorm(10000)
y <- rnorm(10000)

Robust PCA?
Hi.
I'm checking into robust methods for principal components analysis. There
seem to be several floating around. I'm currently focusing my attention on
a method of Hubert, Rousseeuw, and Vanden Branden
(http://wis.kuleuven.be/stat/Papers/robpca.pdf) mainly because I'm familiar
with other work by Rousseeuw and Hubert in robust methodologies. Of course,

Special Delivery from China
I received a sample IP/Speakerphone from my friends in China today.
Asterisk setup was fairly uncomplicated and I had it running as an
extension on my server within a few minutes. Sounds quality of both the
receiver and the speakerphone are fine (wife's opinion). Are there any
tests I should run with this phone?
Following are the specs:

clustering methods in R
Dear R people,
I need to do some work with clustering, but know next to nothing about it
at present. R has (at least) three clustering packages, cluster, mclust,
cclust.
I was wondering if someone can direct me to some good books where I could
find documentation and background on the functions in these packages. The
html help in these packages lists the following as references. Can people

PAM clustering (using triangular matrix)
Hi,
I'm trying to use a similarity matrix (triangular) as input for pam() or
fanny() clustering algorithms.
The problem is that this algorithms can only accept a dissimilarity
matrix, normally generated by daisy().
However, daisy only accept 'data matrix or dataframe. Dissimilarities
will be computed between the rows of x'.
Is there any way to say to that your data are already a

"FANNY" function in R package "cluster"
Dear All,
I am attempting to use the FANNY fuzzy clustering function in R
(Kaufman & Rousseeuw, 1990), found in the "cluster" package. I have
run into a variety of difficulties; the two most crucial difficulties
are enumerated below.

Multiv / hierclust / plclust
I use hierclust (hierarchical clustering) in multiv package. In the
documentation it is said that plclust (plotting a dendrogram) is
available in S-plus. Can I find it anywhere (I have searched through
http://lib.stat.cmu.edu/S and found only quotations of plclust in
multiv) or is it only part of the S package (which I don't have)?
Thanks
