Pseudo-Voigt fit
Hi, I am sorry for this question, but I am trying to speed up an application.... I will need to fit many x-y data sets (input from text files) to 4-parameter Pseudo-Voigt peak function. Until now I used SigmaPlot macro to do it (enclosed just in case...) peaksign(q) = if(total(q)>q[1], 1, -1) xatymin(q,r) = xatymax(q,max(r)-r) [Parameters] a = if(peaksign(y)>0, max(y), min(y))

nls() fit to a lorentzian - can I specify partials?
First, thanks to all who helped me with my question about rescaling axes on the fly. Using unlist() and range() to set the axis ranges in advance worked well. I've since plotted about 300 datasets with relative ease. Now I'm trying to fit a lossy oscillator resonance to (the square root of) a lorentzian (testframe$y is oscillator amplitude, testframe$x is drive frequency): lorentz

Upper limit in nlsLM not working as expected
Dear all, I am using the nlsLM function to fit a Lorentzian function to my experimental data. The LM algorithm should allow to specify limits, but the upper limit appears not to work as expected in my code. The parameter 'w', which is peak width at half maximuim always hits the upper limit if the limit is specified. I would expect the value to be in-between the upper and lower limit with

first value from nlm (non-finite value supplied by nlm)
Dear expeRts, first of all I'd like to thank you for the quick help on my last which() problem. Here is another one I could not tackle: I have data on an absorption measurement which I want to fit with an voigt profile: fn.1 <- function(p){ for (i1 in ilong){ ff <- f[i1] ex[i1] <- exp(S*n*L*voigt(u,v,ff,p[1],p[2],p[3])[[1]]) } sum((t-ex)^2) } out <-

send Q931 information element keypadfacility ?!
Hi all, I'm looking for a way with any asterisk-version with TE410P (cpe EuroISDN, Q931) for sending an INFORMATION ELEMENT KeypadFacility, eg. *87, during a connected call to the PSTN switch.

predict function the other way around
Dear List, Consider the following example x=c(1,2,3,4,5) y=c(2,4,6,8,10) linearmodel=lm(y~x) To predict a y-value if you know the corresponding x value is very easy with the command predict. predict(linearmodel, newdata=(x=1.5)) The other way around, to predict an x-value with a corresponding y-value, doesn't work unfortunately. Is there another function that can do that, or do I need to

Robust Non-linear Regression
Hi, I'm trying to use Robust non-linear regression to fit dose response curves. Maybe I didnt look good enough, but I dind't find robust methods for NON linear regression implemented in R. A method that looked good to me but is unfortunately not (yet) implemented in R is described in http://www.graphpad.com/articles/RobustNonlinearRegression_files/frame.htm

Calculation of normalised red and green intensities
Dear Sir/Madam, I could succesfully normalise my microarray data using marrayNorm package. However, i have not been able to get normalised red and green channel intensities through R package. Is there a possibility to write a formula to calculate back the red and green channel intensities after normalisation of the data. Do I need to incorporate this formula in my R script? I am biologist

Question regarding analysis of normalised data
Dear all, I want to see if the treatment of an animal with a specific compound has an effect on the expression of certain genes. Though my question is based in biology, it really is all about how to deal with the standard deviation in normalised data. I have three groups of animals; untreated, treated with placebo, and treated with a single concentration of the compound in question. Gene

normalised/transformed regressions
Dear R Users, Are there any packages in R which carries out a normalisation to variables as follows: - find the empirical distribution function, using perhaps ecdf - use the empirical distribution function to transform the variables into a series between 0 and 1 - use this series to map the variables into the normal distribution function, using qnorm - perform a regression on the transformed

Can compressed music sound better than uncompressed?
I quote from "Principles of Digital Audio" by Ken C. Pohlmann: "Because perceptual coders tailor the coded signal to the ear's acuity, they similarly tailor the required response of the playback system itself. Live music does not pass through amplifiers and loudspeakers, it goes directly to the ear. But recorded music must pass through the playback signal chain. Much of the

OT: Plate Echo
Oooh Plate Echo was what people had before digital reverbs! (When they didn't have spring reverb!) - Long ago... They are quite rare now because only big studios had them as they took up a lot of room! (and then they threw them all away) *jealous* Do you really have a plate reverb or just a digital simulation? love Freya --- Robert Voigt <robert.voigt@gmx.de> wrote: > uh, you
