Question regarding reading arrayvision files in limma
Hi Everyone,
I have been trying to read some Arrayvision files( 2 channel cDNA) and
am having some
problem. My code is :
setwd('C:/work/data/limma/ndd1');
files <- c('ndd1_1.txt','ndd1_2.txt','ndd1_3.txt');
RG=read.maimages(files,"arrayvision",sep="\t");
#Normalisation
MA=normalizeWithinArrays(RG);
#plotPrintTipLoess(MA);
#Fit Linear

Missing "spline_coef" DLL and Rob Hyndmans monotonic interpolator
Hello R help
I have been trying to use Rob Hyndman's monotonically increasing spline
function. But like another user or two seem have a problem with a
missing DLL (namely "spline_coef"). None of the previous help postings
seemed to have any solutions to this problem. As per a Ripley
suggestion I have deleted all previous versions of R and reinstalled R
2.7.0 and the problem

VERY cool add-on request.
I would like to have the ability to execute a command on a folder based
on a user doing something like copying a message to that folder. This
could be accomplished with a config file directive.
For example, this would be EXTREMEMLY useful as a spam learning hook.
Take a scenario where each user has their own spamassassin bayes database,
and you want to give the users the ability to train their

[LLVMdev] LLVM IR atomics: difference between unordered and monotonic?
Hi All,
I am reading about LLVM IR atomics (http://llvm.org/docs/Atomics.html)
and get confused about the difference between "Unordered" and "Monotonic".
In particular, I am not sure I understand the statement of "It essentially
guarantees that if you take all the operations affecting a specific
address, a consistent ordering exists.". For me, it means that for the

Non-monotonic spline using splinefun(method = "monoH.FC")
Hi,
In my version of R, the stats package splinefun code for fitting a
Fritsch and Carlson monotonic spline does not appear to guarantee a
monotonic result. If two adjoining sections both have over/undershoot
the way the resulting adjustment of alpha and beta is performed can give
modified values which still do not satisfy the required constraints. I
do not think this is due to finite precision

Checking for monotonic sequence
I am scraping data from a web page using XML (excellent package BTW - that's scraping data the easy way!).
So far, I've got the code:
tables <- readHTMLTable(theurl)
rhf <- tables$tabResHistFull
div1 <- rhf[which(rhf$V1=="Div ps"),]
div1
which is giving me the result:
V1 V2 V3 V4 V5 V6 V7 V8 V9 V10 V11 V12 V13 V14 V15

Monotonic interpolation
Has anyone got a function for smooth monotonic interpolation of a
univariate function? I'm after something like the NAG function PCHIM
which does monotonic Hermite interpolation. Alternatively, montononic
cubic spline interpolation.
Please reply directly.

Inversing a non-monotonic spline
I have developed a GAM model in order to predict Y using 4 X variables. 2 of these X's are factors, and 1 is a spline.

Monotonic regression
Hi, I'm trying to find an implementation of monotonic regression in R
and I haven't been able to find anything that's really related to
this. isoMDS in the MASS package uses monotonic regression, however,
I was wondering if there is any standalone function for monotonic
regression?
Basically what I'm trying to do is implement monotonic regression

monotonic clock
Hi,
I've submitted a patch to the Alioth tracker but thought to give a heads up
here as well, I have an issue with nut not working when the clock is moved
backwards. I provided a patch[1] to use clock_gettime with CLOCK_MONOTONIC
to fix this, based on comments from Charles Lepple I made a few changes and
it can be seen in a git branch I created at [2].
Let me know what you think.

Sip Trunking
Hi list,
I have to connect two asterisk box, in this scenario:
[asterisk1]----sip----[asterisk2]----PSTN
I must use sip, cos we'll use cisco rtp header-compression to save
bandwidth.
Could you tell me the best way to send calls from asterisk1 to
asterisk2, since I cannot use IAX trunking?
Thanks in advance

monotonic GAM with more than one term
Hi,
Does anyone know how to fit a GAM where one or more smooth terms are
constrained to be monotonic, in the presence of "by" variables or
other terms? I looked at the example in ?pcls but so far have not been
able to adapt it to the case where there is more than one predictor.
For example,
require(mgcv)
set.seed(0)
n<-100

monotonic factors
Hello all,
I have an ordered factor that I would like to include in the linear
predictor of a binomial glm, where the estimated coefficients are
constrained to be monotonic. Does anyone know how to do this? I've tried
using an ordered factor but this does not have the desired effect, an
(artificial) example of this follows;
n <- 100

[BUG 2.6.32.y] Broken PV migration between hosts with different uptime, non-monotonic time?
Hello,
I encountered the following bug when migrating a Linux-2.6.32.54 PV domain on
Xen-3.4.3 between different hosts, whose uptime differs by several minutes (3
hosts, each ~5 minutes apart): When migrating from a host with lower uptime
to a host with higher uptime, the VM looses it''s network connection for some
time and then continues after some minutes (roughly equivalent to the

re: fishsound decoded callback
I'm not sure anyone is even out there, but if someone is, here's what I've
found out:
The constants don't exist. The constants don't exist because the library
doesn't do what the documentation claims and simply ignores the return value
of the function. It isn't even retrieved, the return value is simply chucked
out.
Maybe the documentation should be updated to let

monotonically increasing smoothing spline
Can anyone point me to a suitable function for fitting a monotonically
increasing smoothing spline?
I think this question has been asked before, and I had a feeling it had
been answered by Simon Wood, but I can''t find it in the archives.

Smooth monotone estimation on R

We would like to apply the smooth monotone function to our data which correspond to a non-linear function.
We follow the example posted on the web, but in our case it did not apply.
We always get a straight line in response.
