I am doing cluster analysis on 8768 respondents on 5 lifestyle variables and am having difficulty constructing a dissimilarity matrix which I will use for PAM.  I always get an error:  “cannot allocate  vector of size 293.3 Mb” even if I have already increased my memory to its limit of 4000.  I did it on 2GB , 32-bit OS .  I tried ff and filehash and I still get the same error.  Can you please

Hey guys, if i do a correspondance analysis, e.g.: table <- structure(c(4, 7, 0.2, 3, .1, 7, 222, 3, 10, 5, 11, 8, 8, 10, 7), .Dim = c(5L, 3L), .Dimnames = list(c("gene1", "gene2", "gene3", "gene4", "gene5"), c("codon1", "codon2", "codon3"))) Library(ca) plot(ca(table)) is there a way that i can see

Hi I am using repeated meaturement data for my project and I want to use quantile regression with multilevel or panel data in "R." I dont find the basic version of software in R, so I have difficulty in using it. I would also appreciate if anyone more proficient in R could help me how to run this. best wishes  M.A-Vakili Department of Biostatistics Faculty of Medicine Shiraz/Iran

Hi! I want to do a meta-analysis with count data for treatement/control cases. Mi problem is that I need to use zero values (an informative value) for the mean and standard deviation for one of the treatement, but R has a problem: "Studies with zero values for sd.e or sd.c get no weight in meta-analysis". I can agroup the case by Family (byvar=Family). ¿anybody help me? Thanks! >

Hello I have been trying to figure out how to randomly select a number of records. I have a column "ID" which contains 16 individuals (numbered 1-16), each individual has a few hundred rows of GPS locations associated with it. I am trying to select a random sample of these individuals (with all their associated GPS locations) to run a kernel density analysis on, and need to repeat this

Dear R-Help Does "The R Package for Multivariate and Spatial Analysis Version 4.0 (Casgrain and Legendre, 2001)" exist on CRAN and under what name? It supposedly has a chronological clustering program ,CHRONO, that I would like to use. Alternatively, I would ask if there is a R based program that performs chronological clustering? Thanks Alex Alex Hanke Department of Fisheries and

Dear group, Thank u so much 4 ur help. I've tried the link, http://finzi.psych.upenn.edu/R/library/quantreg/html/akj.html for adaptive kernel density estimation. But since I'm an R beginer and the topic of adaptive estimation is new for me, i still can't figure out some of the arguments of akj(x, z =, p =, h = -1, alpha = 0.5, kappa = 0.9, iker1 = 0) I've a vector of 1000 values

Is anybody working on this? If not, where might one start looking to fix this? -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of David Blaikie Sent: Monday, January 14, 2013 1:52 PM To: Sebastian Pop Cc: cfe-dev at cs.uiuc.edu Developers; llvmdev at cs.uiuc.edu Subject: Re: [LLVMdev] [cfe-dev] RFC: put commit messages in *-commits

I have no idea to be honest. I have never used the package, I simply did a search for it.

hello, i already include the error in blue color word. i hope it can help you to understand my question. if not burden you, please give me a guide how to correct the error or maybe you can correct the coding cause error. thank you. > # lda.r > # > # Author: Amsha Nahid, Jairus Bowne, Gerard Murray > # Purpose: Perform Linear Discriminant Analysis (LDA) > # > #

Hi All, I am performing GEV analysis on temperature/precipitation data using L moments: dim(data) [1] 145 192 156 Lmoments <- apply(data, 1:2, function(x) samlmu(x,nmom=4,sort.data=TRUE)) params_GEV <- apply(Lmoments,2:3,pelgev) location <- params_GEV[1,,] (xi) scale <- params_GEV[2,,] (alpha) shape <- params_GEV[3,,] (k) I want to use the ks.boot function but I am

Hi, I am exporting an HDF5 file from Matlab (hdf5write function). It contains several datasets: one scalar, one vectory, one 2-D array, and one 3-D array. The hdf5read() function in the hdf5 library seems to load everything except the 3-D array. There are no errors reported even with verbosity=1, as if the 3-D array did not exist in the .hdf5 file. However, I can read the 3-D array back in using

Hi Group, I've a vector of 1000 numeric values for which I want to draw a histogram. I've read this vector into R with no variable name.I mean only the 1000 values, which makes V1 the name of the variable by default?? Then I tried > hist(V1, breaks = "Sturges", +      freq = NULL, probability = !freq, +      include.lowest = TRUE, right = TRUE, +      density = NULL, angle =
