Hi R-users, I am new to R environment.I want to carry out a correspondence analysis on a contigency table with 64 columns and 298 observation of Environmental data.In many cells of the contigency table the frequency is just the value '1'. I got the following error. > CAIV(Eplankton) Error in if (L[i, j] < 0) return("Table L must contain non-negative numbers") :

I apologize that this is not precisely about R, but it does fall into the "what would an R user do?" category of questions. My colleague came to me and said "I have data on 20 countries, 4 elections in each one. I have measures for each election on a number of things, and I want to know if the change from one election to the next follows a pattern. For example, is the measure

Hello, I am trying to run a PCA in R and I cannot get the PC scores for each of the values. Using pcX <- princomp(X) then loadings(pcX) I can get a listing of the eigenvectors but not the actual PC scores for each value in the dataset. I greatly appreciate any help anyone can offer Thanks Ken

Is there an R function that does canonical correspondence analysis. Can it be done using the VR function corresp()? If not, how hard it be to write R code to do it? I am a population biologist with long but patchy programming experience in C, Smalltalk, Java and other languages. Thanks, Patrick Foley patfoley at csus.edu

Any help would

Dear All, I have a set of environental maps and presence-only points for some species. How can I generate distributions models on R using these presence-only data? What packages and functions can I use to do so? Kind regards, Miltinho Brazil [[alternative HTML version deleted]]

Hi, from what I understand about the canonical correlation function 'cancor', it looks for correlations in two sets of variables, each represented in matrix form. Right? Sounds exactly like what I need. I have tried the following but I am not sure how to interpret the results. AudioPCs <- c(ArTHarF0PCA$x[,2], ArTHarF1PCA$x[,2], ArTHarF2PCA$x[,2], ArTHarF3PCA$x[,2],

Hi, I'm having some troubles in using the ADE-4 package. I want to analyze data for the Outlying Mean Index in the function 'niche'. I've got two matrixes: one for environmental data and the other for species abundance data. But to implement the analysis, as I understand it, I need to put tocheger these two matrixes in one, as in the example provided with the package. Un

Hi, i'm having trouble using Statis in ADE4 package. I want to study a matrix with 18x414...could any body help me?!?!' Urgent Thanks Miguel Ribeiro Portugal [[alternative HTML version deleted]]

Hello I'm using the package ade4 to obtain classification from a .txt file. I use the following commands: cronquist <- read.table("cronquist.txt", h = T, row.names = 8) cronquist <- as.taxo(cronquist[7:1]) cro.phy <- taxo2phylog(cronquist) in which cronquist.txt is a file with a classification of 218 genus of tree species from french Guiana. We I try to use the

Dear R-users How can I get the eigenvalues out of an lda analysis? thanks a lot christoph -- Christoph Lehmann <christoph.lehmann at gmx.ch>

Hello list, i have a glm with family=binomial, link=logit but there is over-dispersion. So, in order to take into account for this problem i choose to do a glm with family=quasibinomial(). I'm not an expert on this subject and i ask if someone could validate my approach (i'm not sure for the tests) : quasi_glm(myformula,quasibinomial(),start=mystart) summary(quasi) # test t for

Hello List, i need help for eigen and svd functions. I have a non-symmetric square matrix. These matrix is not positive (some eigenvalues are negative). I want to diagonalise these matrix. So, I use svd and eigen and i compare the results. eigen give me the "good" eigenvalues (positive and negative). I compare with another software and the results are the same. BUT, when i use svd,

I am not sure a previous e-mail reached the list (no mail aknowledgement from R-boundle etc.). The question was how to write polygon or segment coordinates into a shapefile set or any other ArcGIS supported format. The library shapefiles seems to do something but the documentation is a bit beyond of my mind.... and I cannot get the meaning of the functions write**** and its application to the case

Hello, I am trying to use 'R' for K-means simulatio, could you please advise me how I can read my data into a two dimesional array? Or is there any method which directly reads the excell file? Please let me know asap. Regards Skanda Kallur Cogito, Ergo Sum! Rene Descartes

Is there a function in R for calculating empirical cumulative distribution functions, i.e. the inverse of the quantile function? Perhaps in some library? I''d hate to have to re-invent the wheel.

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 ?
