Dear list members, I have a statistical question, that doesn't belong to this list, and I apologise for that in advance but I would appreciate your help very much. Is there some convention for selecting the a level for significance testing in scientific (e.g. chemical processes) studies? Most people use the 0.05 level but I could not find a reference to justify this. Why not 0.01 or 0.1?

Hi list, not really a problem to solve but a strange unwanted behavior (at least I do not like it): I'm loading library(multiv) to use sammon. Later I load library(MASS) which tells me that sammon is masked now, because there is also a MASS version of sammon. Since I believe that the MASS version is at least as good as the multiv version, I would also use the MASS version, but help(sammon)

Dear R team / R helpers / R users , I downloaded R-1.0.0 to install it but I am currently facing the following problem : Installation of packages.

Hi, Win95 version, trying to build multiv. Following error (no mention in faq etc, but someone may have mentioned it recently). Appreciate any help. ------- Building multiv.dll from multiv.a -------- echo LIBRARY multiv > multiv.def echo EXPORTS >> multiv.def nm multiv.a | sed -n "/^........ [DT] _/s/^........

Please, forgive my ignorance on statistics, but I have a rather simple question concerning AIC. Small values of AIC mean good fit of the model. How about negative values of AIC? Is a model with AIC=0.5 considered to have better fit than a model with AIC=-500? I couldn't find anything explaining this in the documentation or any elementary statistics textbook that I have at my disposal. Thanks

Hello all, I am somewhat new to S-plus and would really appreciate any help you might have on the following problem: I installed S-plus (0.65.1) on a Sun box (Solaris) and it runs fine as far as I can tell. I also installed the cluster and multiv contributed packages. The problem I have is that I get a core dump everytime I try to run a function in the contributed packages. This seems

Hello list members, I am new to this list and don't know very much about what R can do or how to program it, but I am interested in plotting 4 variables as sequential contour plots (or surface plots), something like the conditioning plots for 4 variables (coplot(X1~X2|X3+X4)). To be more specific, I need a tool that will automatically create contour (orsurface) plots of X1 vs X2 vs X3 for

I'm not sure this list is the right place for this thing. I noticed some erratic behaviour in sammon(). Running sammon on two nearly identical sets of data results in very different results. Below is an example. I create an initial configuration with cmdscale() and store it into 'vec1'. I write this to file, and read it back in again to 'vec2'. According to cor() on the three

Dear list members, this is not an R question and forgive me for using the list for irrelevant questions, but this is the only place I know where I can find some good statisticians and I need an expert opinion. There is this power law kinetic model of the form: M=kt^n where t is the time, M is the fraction of drug released, k is the rate constant and n is an exponent related to the mechanism of

Hallo Friedrich, I have read your announcement, downloaded and installed it in R-0.61.3. But now I have problems :) > hc <- hierclust(dist(t(pollen)), method=3) Error in pmatch(x, table) : argument is not of mode character > hc <- hclust(dist(t(pollen))) > members(hc) Error in .Fortran("assgn", n = as.integer(n), nplus1 = as.integer(nplus1), : C/Fortran function not in

Hello, I am inputing a 17 x 17 symetric matrix to sammon. The matrix is a co-occurance matrix with no missing data. If this is at all relevant, running hclust on this matrix works. > samx <- sammon(q23axproduct) I receive the following error: Error in sammon(q23axproduct) : initial configuration must be complete In addition: Warning messages: 1: some of the first 2 eigenvalues are

Dear all, I'm trying to get a two dimensional embedding of some data using different meythods, among which princomp(), cmds(), sammon() and isoMDS(). I have a problem with sammon() because the coordinates I get are all equal to NA. What does it mean? Why the method fails in finding the coordinates? Can I do anything to get some meaningful results? Thank you very much Domenico

Hello, I have a data set on which I run the sammon algorithm as follows: library(MASS) data = read.table('problemforr.dat') y = cmdscale(data, add=TRUE) s = sammon(data, y$points) (In case it should be relevant, I make the data available at http://idi.ntnu.no/~edsberg/problemforr.dat) With R 2.2.1 on Debian Sid I always get one of two solutions (stress 1.74288 after 10 iterations or

I use hierclust (hierarchical clustering) in multiv package. In the documentation it is said that plclust (plotting a dendrogram) is available in S-plus. Can I find it anywhere (I have searched through http://lib.stat.cmu.edu/S and found only quotations of plclust in multiv) or is it only part of the S package (which I don't have)? Thanks --------------- Charles RAUX, Laboratoire

If tbl is an object of class 'dist', you can do this: a <- sammon(tbl, k=3) But you can't do this: b <- isoMDS(tbl, k=3) Wouldn't it be sensible to have identical interfaces to sammon() and isoMDS() ? I think all that would be needed is to change this: isoMDS <- function(d, y=cmdscale(d, 2), maxit=50, trace=TRUE) { ...into this: isoMDS <-

Hello, I just have upgraded from Mandrake 8.1 to 8.2 and installed R 1.5.1.

What happened to multiv package? I have installed R 2.0.0 in my Mac and I could not find this package. I see other things have been reorganized. I have read "What's New" and I have used the search facility in the RHelp panel to no avail. Oscar A. Moreno oscar.moreno at att.net
