search for: uninformative

I am trying to generate artificial data for feature selection. Basically trying to generate a total of 1000 features with 100 that are informative and rest are uninformative. Informative.data.class1<-rnorm(100,0.25,1) Uninformative.data.class1<-rnorm(900,0,1) Informative.data.class2<-rnorm(100, -0.25,1) Uninformative.data.class2<-rnorm(900,0,1) The above will give me one set of data for the two classes. I am interested in generating about a 100 set for eac...

...7-178 > ################################################### > peRes <- pe(x = fc, graphs = kpg, ref = ref, nboot = 200, verbose = FALSE) Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd' It would be great if R CMD build could produce this error instead of the uninformative ?x? must be an atomic vector. I see this with many different packages and I always have to do the same dance in order to find out what is really going on. BTW, I don't think it's referring to the x in the line of code right before the error, because that x is an atomic vector: > cla...

Hello, I'm using recursive SVM script (rSVM - http://www.stanford.edu/group/wonglab/RSVMpage/R-SVM.html ) on some microarray data. The data to be input are log2, as numeric matrix w/ attributes -- str(svm_num_mat) num [1:10, 1:12340] 13.1 13.1 13.1 13.1 13.0 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:10] "rma_log2_con_sample_1"

I just saw the following using R version 2.4.1 (2006-12-18) in output from R CMD check. * checking Rd files ... WARNING Error in as.vector(x, mode) : invalid argument 'mode' Execution halted See the chapter 'Writing R documentation files' in manual 'Writing R Extensions'. In looking at the help page (the only one in the package so far) I noticed that

Hello, Anyone have any luck getting storeconfigs + MySQL working? I was getting some freaky uninformative errors: err: Could not call: wrong number of arguments (1 for 0) It''d be great if we could get a wiki page up, there appears to be a pretty large consensus of people who are unable to get it running. Regards, AJ

...e end of the study with people who die of heart disease? Can I just censor them exactly the same as people who become uncontactable or who die in a plane crash? If not, why not? I'm thinking that heart disease isn't independent of smoking even though a death from heart disease is probably uninformative about colorectal cancer risk. Hence I suspect simply censoring these deaths will introduce a bias, but I don't know how to correct for it. Many thanks, Geoff Russell -- an interested student

Hi, I have discovered that sample() fails with an uninformative error message when the x argument is a single NA of type double or integer. I can reproduce the problem with the following code: base::sample(NA) # NA is of logical type above base::sample(NA_character_) base::sample(NA_complex_) base::sample(NA_real_) base::sample(NA_integer_) The last two lin...

Hi folks, I thought I recalled a request for turning a character string into an object name as in: x$as.name("y")<-1:4 OR x<-data.frame(as.name("y")=1:4) However, as.name and a few other uninformed attempts didn't even come close. A search of "character to name" produced no helpful functions. This isn't a very urgent request, but if anyone knows

Hello, I would like to ask for some specialist assistance in dissecting a 'rootkit' (seems to be massmailing specific,crafted somehow from another kit perhaps) It was found running on 5.x machines belonging (sofar) to my knowledge, 2 companies,one of wich was an isp and another a webhosting service running bsd. I will provide the kit and further details as soon as i am sure the thing will

Hi there, Is there an implementation of the Gaveh Stehfest algorithm in R somewhere ? Or some other inversion ? Thanks, Tolga

...presentation graphics generated in R with the SVGAnnotation package, here:http://www.omegahat.org/SVGAnnotation/http://www.omegahat.org/SVGAnnotation/SVGAnnotationPaper/SVGAnnotationPaper.htmlI tried to install the package available at that website (it's not on CRAN) and am getting some pretty uninformative errors (see below). My best guess is that the package worked under an earlier version of R but is broken now. Do any of you use this package for interactive presentation graphics? Or, what are some good alternative libraries? I've played around a bit with 'iplots' and RStudio's...

While considering statically linking against libc++ (and other runtime libraries from LLVM), I rebuilt LLVM 4.0 with -DBUILD_SHARED_LIBS=OFF. There are still some .so's in llvm/lib, and only one of them seems to exist exclusively as a DSO (libLTO). There's also livLLVMLTO.a, but I doubt LTO is used after linking a binary so this just looks odd to an uninformed LLVM outside and not

...'ggplot2' depends on package 'Rcpp', but 'Rcpp' is not installed consider installing 'Rcpp' with install.packages("Rcpp") In other words, it might be helpful to avoid printing the 'loadNamespace()' call on error (since it's mostly just scary / uninformative), and check up-front that the package is installed before attempting to call 'loadNamespace()'. I'm sure a number of novice users will still just throw their hands up in the air and say "I don't know what to do", but I think this would help steer a number of users in the r...

I'm trying to get veracity (http://www.rocksoft.com/veracity/), a tripwire replacement, working on FreeBSD 5.x.

First let me admit that I'm completely uninformed here! 1. Will llvm produce errors if llc is used to compile itself? 2. Will make produce subsequent errors if compiled first by llc/llvm? 3. Can llc be used to compile the entire Linux toolchain? Shingoshi --

Dear List, I have a dataset that provides sampling weights (National Survey of Family Growth 2002). I want to produce a cross-tabulation and use the provided sampling weights to obtain representative population estimates. (I believe they are simply frequency weights but codebook is uninformative). I can reproduce results (using this data) that were reported in a recent journal article, if I use SPSS or STATA--specifying the weight. Does anyone know how to do this in R? I have read a lot of documentation and this is my last resort. Thanks in advance, Tom Volscho

I want to read in a binary file using the readBin() function. In order to skip uninformative parts of the file I use the seek() function, I need to specify the number of bits to skip rather than the number of bytes to skip. E.g. seek(to.read,origin="current",blockSize) with blockSize giving the number of bits Does anybody know if this works? Any help would be highly a...
