similar to: plot(corresp(data)...)

Is it possible to do a graphic in 3D? This is my source: but this one is on 2D and at moment variables put on other variables, so it is difiicult to differentiate them visibly. plot(corresp(data,nf=2),xlim=c(-1,1),ylim=c(-1,1)); Thanks Sabine --------------------------------- ils, photos et vidéos !

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, to use the function plot3d, i should use the package R.basic! plot3d {R.basic} If people know exactly a site to load this package, please give me the URL! Thanks Sabine --------------------------------- [[alternative HTML version deleted]]

Hello I will be applying MDS (actually Isomap) to make a psychological "concept map" of the similarities between N concepts. I would like to scale to a large number of concepts, however, the resulting N*(N-1) pairwise similarities is prohibitive for a user survey. I'm thinking of giving people random subsets of the pairwise similarities. Does anyone have recommendations for this

I've been unable to find a R package that provides the means of performing Clarke & Ainsworth's BIO-ENV procedure or something comparable. Briefly, they describe a method for comparing two separate sample ordinations, one from species data and the second from environmental data. The analysis includes selection of the 'best' subset of environmental variables for explaining

Hi, I would like to know the similarity between variables, but I don't exactly how begin and as from what dataframe or matrix!

Thanks a lot Sabine --------------------------------- ils, photos et vidéos ! [[alternative

I just noticed that two key pieces of information are not given by the summary() command: N and SD. we are given the N missing, but not the converse. I know these summary value can be obtained easy, but can't understand why these two pieces of information are not provided with the other info. Thanks, Gerard

Dear all, I didn't find any graphical solution in the package "mva" to plot the canonical scores from a CCA (canonical correlation analysis). Does anybody knows how to plot or has anybody already programmed : - the map of the canonical scores, - the graph of the canonical weights, - the correlation circle i.e. the canonical loadings ? Thank you for help ...

hi, is it possible to create a matrix with one row and according to add a row? in fact, at present, I'm doing an algorithm which fill a matrix.

Hi all, I'm trying to perform an MDS of some data that I have. When I use cmdscale everything is fine and I get some interesting results however, the tends to be low. What I wnat to do is compare this with the Non-Metric MDS using isoMDS or sammon. However, when I try using these I get the following message. Error in isoMDS(x.dist) : zero or negative distance between objects 2 and 4

Message 2 of today: it works now. After re-installing R.app from the same R-2.1.0.dmg file, and fixInNamespace'ing(*) install.packages(), I managed to update 23 outdated packages from CRAN binaries for MacOS X. What I did was to: 1. change call to .install.macbinaries() into call to install.binaries() in install.packages(). install.binaries() is a function defined utils/R/aqua/GUI.R. 2. I

Dear all, in package Hmisc `rcorr' computes a matrix of Spearman's `rho' rank correlation coefficients for all possible pairs of columns of a matrix. What if I want a matrix of rank correlation coefficients for pair of columns of two different matrices? I have the same question about distance metrics in package Vegan. The function 'vegdist' computes distance indexes for all

On my computer, it seems that (binary?) packages installed through the GUI in RAqua are not used available to the command line version of R, while (source) packages installed with R CMD INSTALL are available to both. This is a problem when I run R CMD CHECK on a package that I am creating that depends on packages I have installed through the gui. Is this a problem with my installation of R, or a
