Hi This is a question regarding classification performance using different methods. So far I've tried NaiveBayes (klaR package), svm (e1071) package and randomForest (randomForest). What has puzzled me is that randomForest seems to perform far better (32% classification error) than svm and NaiveBayes, which have similar classification errors (45%, 48% respectively). A similar difference in

You need to give us more details, like how you call randomForest, versions of the package and R itself, etc. Also, see if this helps you: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/32918.html Andy From: Eleni Rapsomaniki > > Dear all, > > I am trying to train a randomForest using all my control data > (12,000 cases, ~ 20 explanatory variables, 2 classes). > Because

Hello, (Apologies for length, wanted to get all the relevant detail in that I know of). I've been having a lot of trouble with some code for an inventory analysis problem I was doing, and finally came to the conclusion that it appears that choose() is returning incorrect values. Specifically: ------------- Browse[1]> nn [1] 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3

Hello everybody, i already searched the archieves, but i still don't know what is wrong in my implementation, mybe anybody coud give me some advice ll1<-function(rho,theta,beta1,beta2,beta3,beta4,t,Szenariosw5,Testfaellew5,X1,X2) { n<-length(t) t<-cumsum(t) tn<-t[length(t)] Szenn<-Szenariosw5[length(Szenariosw5)]

Dear Dr Hornik / R help list, I am using the mda package and in particular the fda routine to classify a set of 162 neurons falling in to 11 neuronal cell types according to 17 morphological variables. I would like to use a cross-validation approach in which I split the data, train with one part amd then test the predictive accuracy of the discriminant functions with the remaining part. However

Hi, I can build LLVM just with VS2010 x64. However, when I try to build it with -DBUILD_SHARED_LIBS:BOOL=true option, it seems to fail with a lot of unresolved external symbol. Is it a known issue? Is there anyway to fix it? Thanks, http://old.nabble.com/file/p31351142/build.log build.log -- View this message in context:

Camping now comes with a sessioning class, checked in tonight. To get sessions working for your application: 1. require ''camping/session'' 2. include Camping::Session in your application''s toplevel module. 3. In your application''s create method, add a call to Camping::Models::Schema.create_schema 4. Throughout your application, use the @state

Hi, this is my first time using R. I want to simulate the following process: "in a population of size N, there are i individuals bearing genotype A, the number of those bearing A is j in the next generation, which following a binominal distribution (choose j from 2*N, the p is i/2*N), to plot the probability of the next generations, my script is as follows. It cannot run successfully,

I know about the current.row, current.column, and panel.number functions that are useful within panel functions written for lattice. Are there easy ways to obtain the names of the conditioning variables (those appearing after |) and their values for the current panel?

Hi, I had the following code: testp <- rcorr(t(datcm1),type = "pearson") mat1 <- testp[[1]][,] > 0.6 mat2 <- testp[[3]][,] < 0.05 mat3 <- mat1 + mat2 The resulting mat3 (smaller version) matrix looks like: NA 0 0 0 0 NA 0 NA 0 0 NA 2 0 0 2 NA To get to the number of times a '2' appears in the rows, I was

I have a question with llvm-gcc and llvm-gfortran. Is it possible that llvm-ld can combine different bc files compiled from C programme and Fortran Programme together? For example: Compile a c program into llvm bc file by the task: # llvm-gcc -emit-llvm test.c -c -o test.bc and then compile a fortran program into llvm bc file by the task: # llvm-gfortran -emit-llvm testf.f -c -o testf.bc And

Thank you for your reply. I have managed to create a virtual machine on my ZFS-filesystem using virt-install:-) It seems to me that my version of libvirt (Ubuntu 17.04) has problems enumerating the devices when "virsh vol-list“ is used. The volumes are available for virt-install but not thru virsh or virt-manager. As to when the volumes disappear in virsh vol-list - I have no idea. I’m not
