Last week (Wed 9/10/2003, "regression questions") I posted a question regarding the use of gnls( ) and its dissimilarity to the syntax that nls( ) will accept. No one replied, so I partly answered my own question by constructing indicator variables for use in gnls( ). The code I used to construct the indicators is at the end of this email. I do have a nagging, unanswered

First, I am really liking what I have seen so far in R. The demos are quite fascinating, and I look forward to doing some really neat stuff over the next little while with R. Being but an intiate to R, I am having quite a bit of trouble figuring out how to use the leaps library. Rather than ask several questions to the list at large, I would rather explain what I'm trying to do to someone in

I got a question from a fellow PhD student that work with spectrum analysis in Excel and now he has lots of spectrums that needs to be smoothed, which would be nice to be able to do in batch. Is there an R package that can do: Savitzky-Golay smoothing for reflectance spectral data or a function that does something similar. _______________________________________ Henrik Andersson

hi R-help! I would like to know a simple and easy way (if posible) to do the following data manipulation. I have a matrix of experimental data (with replicae in time) >experiment<-data.frame(times=c(0,0,10,10,20,20,30,30),expval=c(1,1,2,2,3,3,4,4)) > experiment times expval 1 0 1 2 0 1 3 10 2 4 10 2 5 20 3 6 20 3 7 30 4 8

I'm written a function that uses nls in a loop to fit a model to resampled data. Occasionally a sample is drawn such that the algorithm (apparently) can't converge and step factor reduced below minimum is printed to the screen. I tried a few different settings for the minFactor parameter in nls.control with no different result. When this happens, I would like my function to put NAs

Hello, I might have missed it in the help pages, but I cannot find if something exits in a package to make discriminant analysis.

Forgive this naive question, but I'm not accustomed to using Win ports of Unix tools (actually I'm unfamiliar with Unix tools, period). Anyway, I've successfully compiled the R-1.1.1 sources into the full binary package. Everything seems to work. I'd like to remove all the "made" files and leave only the original source code and the compiled binary code. Is there

Hi there, I'm trying to fit a growth curve to some data and need to use a weighted least squares estimator to account for heteroscedasticity in the data. A weights argument is available in nls that would appear to be appropriate for this purpose, but it is listed as 'not yet implemented'. Is there another package which could implement this procedure?

A couple of months ago I downloaded R 1.6.0's binary for Windows, which I have since been using without any particular problem, that is on one machine running Windows 98. Last week I set up a local network and have since tried to use R remotely, i.e. R is installed on the previous machine and nowhere else. On the client's side, the GUI opens correctly and allows me to do simple

Peter, As I understand your Q. You probably have data that is similar to each other like stock Prices for all RHS variable. In that case the difference between corr and cov is not significant; however, if your RHS contains totally dissimilar variables it matters a great deal. If x1 income, x2 job type, x3 Education level, etc..., then taking cov of these variables would not be desireable
