Dear all, when I try to install gtkDevice on Mandrake Linux 9.1 (R v. 1.7.1), I get the following comfiguration error (see below). Has anyone else had this problem? Any hints are greatly appreciated. Thank you in advance, Dimitri install.packages("gtkDevice") trying URL `http://cran.r-project.org/src/contrib/PACKAGES' Content type `text/plain; charset=iso-8859-1' length

I need to make automatic voice calls from a Linux server, so when the system receive special "signals" it must use a wave (or .au) audio file, dial the number to call a person, and "speak" using the audio file. What can i use for this subject? I need a specific hardware device or a normal analogic voice-modem is ok? which software can i use (i need to invoke from a Perl

hi! i want to change the "robustness weights" used by loess. these are described on page 316 of chambers and hastie's "statistical models in S" book as r_i = B(e_i,6m) where B is tukey's biweight function, e_i are the residulas, and m is the median average distance from 0 of the residuals. i want to change 6m to, say, 3m. is there a way to do this? i cant

I'm updating the loess routines to allow for, among other things, arbitrary local polynomial degree and number of predictors. For now, I've given the updated package its own namespace. The trouble is, panel.loess still calls the original code in package:stats instead of the new loess package, regardless of whether package:loess or package:lattice comes first in the search list. If I

I gave you the most simple option. And the difference is. myserverdomain\username works only on that server. (myserverdomain) .\username works on any server where the loginname and password are the same. There is NO other option for you that i know off. (sorry) Yes.. the other option is, setup an AD domain.

Hi, I have 2 questions regarding using loess function in stats package. 1. I have about 1 million points. I did loess with alpha=0.5 and degree=1 and 2 regressors. It has run for more than 5 hrs on 64bit 16CPU and 64GB server (with no other process running). I am wondering if this is usual? And if there is anyway to make it run faster? 2. I noticed a difference in RAM consumption when specifying

Hello, I am interested in performing a 2D loess smooth on microarray data, i.e. log2 ratios on a 2D grid, using different spans in the horizontal and vertical directions (the immediate reason being that replicate spots are laid out in the horizontal direction). Is it possible to do this in R? Functions like loess(stats) seem to apply the same span for all predictors, which carries over to

is there a way of estimating derivative curves, similar to the ones we get from 'locpoly', from 'loess' estimation. i am interested in estimation of 1st and 2nd derivatives... --------------------------------- [[alternate HTML version deleted]]

Hi I am trying to get the tricube weights from the loess outputs as I need to calculate an error function which requires the weight. So I have used the following example from the R: cars.lo <- loess(dist ~ speed, cars, span=0.5, degree=1, family="symmetric") Then i try to get the weights: cars.lo$weights [1] 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

Hi, Our firm is looking to see if it is possible to wrap some of more advanced lib in R like modreg.dll and specifically Loess function in there for both regression and prediction into MSVC++. We will probably take it to either VB or Python for implementation issues. Given that locfit has many utitlities built in for data transformation, this would be a good thing. If that's not

May I inquire about how to obtain the coefficients from a loess fit of multiple covariates? I have tried terms and coef, but it does not provide me with the coefficients to identify the terms of the entire regression equation. Many thanks Paul -- Paul R. Hutson, Pharm.D.

Dear R Users, Does anyone know if I can somehow "right" align the loess function, so it only uses data points up to a certain date, and not around it ? Sort of like rollmean(...align="right") in the rollmean function.

Hi, I wonder why my attempt to extend an existing loess fit to a new data set is producing error. I was trying the following: dat = read.csv(choose.files()) x = dat[,2]; y = dat[,1] x.sort = sort(x) y.loess = loess(y~x, span=0.75) # For testing the above fit with a new dataset: test = read.csv(choose.files()) # test data new_x = test [,1]; new_y = test[,2] new_x.sort = sort(new_x) predicted

Hello all, I wish to fit a loess smother to a plot of Y`X, but in predicting the 95% quantile. Something that will be a combination of what rq (package quantreg} does, with loess. Is there a function/method for doing this?

Dear all, I have been using normalize.loess and I get the following error message when my matrix contains NA values: > my.mat = matrix(nrow=100, ncol=4, runif(400) ) > my.mat[1,1]=NA > my.mat.n = normalize.loess(my.mat, verbose=TRUE) Done with 1 vs 2 in iteration 1 Done with 1 vs 3 in iteration 1 Done with 1 vs 4 in iteration 1 Done with 2 vs 3 in iteration 1 Done with 2 vs 4 in

Good morning, I am Marta Colombo,student at Politecnico,Milan. I am studying local regression models and I am using loess function. My problem is that when I have a loess object I don't know how to display the fitted surface; in fact, while in S when you have a loess object you can see it writing plot(object), in R this dosen't work. Also I'd like to know if there is something like the

Hi, For some reason I have been unable to use the predict function when I desire the standard error to be calculated too. For example, when I try the following: l<- loess(d~x+y, span=span, se=TRUE) p<- predict(l, se=TRUE) I get the following error message: Error in vector("double", length) : vector size cannot be NA In addition: Warning message: In N * M1 : NAs produced by

Hi, We noticed a difference between R versions 1.9.1 and 2.0.1 concerning the loess function. The resulting fitted data is quite different. Furthermore, with the 2.0.1 release, if I apply the loess function several times on the same input data set, I get different results. Has anybody already noticed such a problem ? Thanks Marie-Agn?s
