S-code for piecewise regression
Dear R-helpers,
a S-code for piecewise regressions was provided by Toms & Lesperance
(2003) Ecology, 84, 2034-2041 (paper can be found on the web).The code
is quite complete with different types of transitions around breakpoints
and model selection fonctions.
It doesn't work directly under R due to some "translation" problems I
guess. However I reckon that it would be a

strange results with dmvnorm
I am experiencing strange results using dmvnorm. I define a scaled distance
matrix from the coordinates bellow and then calculate a covariance matrix using
a spherical correlation function. Then with certain combinations of
range and sill parameters dmvnorm is returning values greater than 1. Surely
the results of dmvnorm should be in the interval 0:1 (or do I just nead a
holiday?). In addition

Dovecot Bulletin
I'd like to revisit and old post if I may, will/does Dovecot support the old
qpopper "Bulletin" ability?
Basically I need a simple way of posting bulletins to all domain users.
Qpopper maintained a bulletin db for each user and sent them the next
bulletin in sequence.
Thanks in advance

[LLVMdev] git Status Update?
Have we made any progress on a potential git conversion? AFAIK the only
outstanding technical issue is the monotonic revision number question.
Personally, I have no nead for them but others have expressed
reservation about losing them.
Can we have a discussion about that to identify the core tasks currently
needing monotnic revision numbers and how they might be accomplished
under git?

dovecot bulletins?
As a long term user of qpopper with bulletins, I'd like to know if the
bulletin feature is planned for dovecot? I really miss bulletins :-),
this is very convenient way of providing information to users.

how to draw two histograms in one figure
How do you draw two histograms in one figure? Two separate uses of the
"hist" function always produce two separate figures... Thanks, Roman

Bivariate Partial Dependence Plots in Random Forests
Hello,
I was wondering if anyone knew of an R function/R code to plot bivariate
(3 dimensional) partial dependence plots in random forests (randomForest
package).
It is apparently possible using the rgl package
(http://esapubs.org/archive/ecol/E088/173/appendix-C.htm) or there may
be a more direct function such as the pairplot() in MART (multiple
additive regression trees)?

classification table in logistic regression
Prof. Harrell,
My name is Armida Carbajal, I'm a graduate student intern at Sandia National Laboratories (SNL) and am conducting some research for my thesis project at the University of New Mexico in Statistics for SNL.
My project entails a logistic regression and I wanted to create a classification table like the one found in SAS using the function CTABLE. I was running out of ideas on

multivariate splits
Dear R users!
Does someone know about any algorithms / packages in R, that perform
classification / regression / decision trees using multivariate
splits?
I have done some research, but I found nothing. Packages "tree" and
"rpart" seem only to be able to do CART with univariate splits.
Thank you for your help!

message-of-the-day feature?
For lack of a better name, we are interested in a feature where one could
get a notice out to all Dovecot users as quickly as possible, possibly
without going through an MTA even. Given a message and a list of userids
we could certainly do a mailing on the MDA server itself going through
both Postfix and Dovecot LDA. However, we were wondering what other options
we might have in Dovecot. For

SPSS-like factor analysis procedure
I've read through many postings about principle component analysis in
the R-help archives, but haven't been able to piece together the
information I need. I'd like to recreate an SPSS-like experience of
factor analysis using R. Here's what SPSS produces:

bridge interfaces in dom0
Hi. I have another question, hopefully easier than my last:
Do all physical interfaces in dom0 need to have an IP addresse in
order to be used
as a bridge by guest domains?
I thought that the interface would have to merely be "up" but not
necessarily have an
IP address configured since bridging is done at layer 2. But alas, if
I don''t configure
an IP address on dom0 the bridge

Win32 gems for mongrel (0.3.18) and mongrel_service (0.3.1)
Hello Users!,
Since the pre-release 0.3.18 (last week) Lot of things happen in
ruby-land (check the DoS security bulletin, please).
Anyway, the win32 folks being left on the side of the road, and cannot
provide feedback of stability due lack of binaries for the latest
releases.
So, I managed to upload the pre-built gem to my host:

Plotting frequency curve over histogram
Hello,
This is a problem for which there seem to be several solutions online, but
not really. My question was about plotting a curve over the histogram. All
the previous posts and messages talk about generating a *density
histogram*using (freq=F) and then plotting the density curve. However,
I find that
that seriously distorts my data and the plot becomes confounding to the
viewer.

overlaid transparent histograms
Hello all--
I'm attempting to produce overlaid histograms with partially transparent
columns. Whether this display will end up being useful, I can't say.
But I do want to get it right.
I've already got one solution (shown below), but I tried some other
versions and had questions about my results. (Note: I'm using a quartz
device, so transparency shows up correctly. You might

Choices for shared network storage, NFS vs iSCSI
Has anyone here ran performance comparisons between NFS and iSCSI when
using network storage for KVM based guests. Also which have people found

Removing "row.names"
I need to completely remove row.names from a dataframe. Are there other
ways to remove them (and not anything else) besides:
mydataframe<-data.frame(mydataframe, row.names=NULL)
I realize that this doesn't really remove the row.names; it merely replaces
the current row.names vector with the numbers 1..nrow (in quotes).
