Hello, can anybody tell me if there exists functions for DTW in R? I didn't find anything at CRAN's search page... Also any information about packages for time series preprocessing (for pattern matching) would be useful... Thanks a lot, ondra

Hello, I'm tasked with putting together a cost effectiveness analysis on a proposed medical treatment. The "standard" suggested by someone is an expensive commercial package names "TreeAge Pro" which looks like its just a fancy GUI on top of a decision tree. However, we don't have it and it is expensive to buy. Questions for the group: 1) Are there any interesting

I like what smooth.spline does but I am unclear on the output. I can see from the documentation that there are fit.coef but I am unclear what those coeficients are applied to.With spline I understand the "noraml" coefficients applied to a cubic polynomial. But these coefficients I am not sure how to interpret. If I had a description of the algorithm maybe I could figure it out but as it

Dear "R" users, I have a question about the Package DierckxSpline. I have tried to find the answer by myself but it didn't worked out. I wondered if Dierckxspline can use different sets of y values in one time to fit a line with knot. I have different sets of Y values representing the same thing for different voxels (in an fmri image). I have already fitted the data in different

fda 1.2.3 ======================== Version 1.2.3 of the fda package has just been released. This version adds to previous versions a script to create most of the figures of chapter 6 of "Applied Functional Data Analysis" by Ramsay and Silverman. Other changes offer simpler calls to time warping / registration and functional principal component functions. The fda package supports the

Basically all I want to do is predict a scalar response using some curves. I've got as far as doing a regression (using fRegress from the fda package) but have no idea how to apply the results to a NEW set of curves (for prediction). I have N=536 curves, and 536 scalar responses. Here's what I've done so far: * I've created a basis for the curves. * I've created a

Dear all, Another newbie just got attracted to this mailing list. I am a biologist currently working my way through R, had sort play around with python earlier this year. I have some data exhibiting periodicity ** my data consists of peaks and valleys, with peaks arising due to the presence of a repetitive structural unit,** with x being a reference grid (position along a chromosome) and y

I remember seeing something somewhere that described how I could get SIP header information with Asterisk. It was a command or a variable. Anyone know what it is? Thanks. Doug.

Dear Readers: I have two issues in nonparametric statistical analysis that i need help: First, does R have a package that can implement the multimodality test, e.g., the Silverman test, DIP test, MAP test or Runt test. I have seen an earlier thread (sometime in 2003) where someone was trying to write a code for the Silverman test of multimodality. Is there any other tests that can enable me to

Dear friends - We have 25 rats, 14 of these subjected to partial removal of kidney tissue, 11 to sham operation, and then followed for 6 weeks. So far we have data on 26 urine metabolites measured by NMR 7 times during the observation. I have smoothed the measurements by b.splines in fda including a roughness penalty, and inspecting the mean curves for nephrectomized and sham animals indicate

Hi all, I am setting up a new AD server with Samba 4.1.11 from the FreeBSD ports. I struggle with the internal DNS. I add a new CNAME record but it does not show up properly. I gave the AD domain a new DNS domain (domain.fda) and the server the name samba4.domain.fda. I am using the internal DNS, and a forwarder to a bind server in the same network. After the AD provision I have this here

Hi, All: What might cause "R CMD check" to report, "could not find function" for a function that has long been in the 'fda' package? Both Jim Ramsay in Ottawa, Canada, and I in San Jose, CA, get this same error. I replicated it with a fresh, anonymous checkout from R-Forge (svn checkout svn://svn.r-forge.r-project.org/svnroot/fda). With this, I did

Hello: What do you recommend I do to get past cryptic error messages from "R CMD check", complaining "No such file or directory"? The package is under SVN control, and I reverted to a version that passed "R CMD check", without eliminating the error. The "00install.out" file is short and bitter: cat: ./R/Copy: No such file or directory cat:

Yesterday I just noticed the new document on R and regulatory aspects for biomedical research posted at http://www.r-project.org/doc/R-FDA.pdf Coming from an institution that performs a large number of clinical trials for FDA and being an advocate of R myself, I have found that the following issues usually come up when discussing the use of R for FDA trials: 1. Most FDA submissions come down to

Dear R community, I would like to introduce the package "dtw" for computing Dynamic Time Warping (DTW) alignments and related algorithms on timeseries. The DTW algorithm computes the time axis stretch which optimally maps one timeseries (query) onto another (template); it outputs the resulting cumulative distance between the two inputs, which is frequently used for classification and
