Hello, I'm running some code that requires untaring many files in the first step. This takes a lot of time and I'd like to do this in parallel, if possible. If it's the disk reading speed that is the bottleneck I guess I should not expect an improvement, but perhaps it's the processor. So I want to try this out. I'm working on windows 7 with R 2.15.1 and the latest foreach

I am trying to compile the R package "KernGPLM" found here: http://www.marlenemueller.de/KernGPLM/KernGPLM_0.65.tar.gz since the binary available is for R 2.4. but the compilation ends with the error message: *** arch-i386 ERROR: compilation failed for the package 'KernGPLM' Here is my session info: R version 2.14.2 (2012-02-29) Platform: x86_64-pc-mingw32/x64 (64-bit)

I want to use the caret package and found out about the timingSamps obtion to obtain the time which is needed to predict results. But, as soon as I set a value for this option, the whole model generation fails. Check this example: ------------------------- library(caret) tc=trainControl(method='LGOCV', timingSamps=10) tcWithout=trainControl(method='LGOCV')

The following code fails to train a nnet model in a random dataset using caret: nR <- 700 nCol <- 2000 myCtrl <- trainControl(method="cv", number=3, preProcOptions=NULL, classProbs = TRUE, summaryFunction = twoClassSummary) trX <- data.frame(replicate(nR, rnorm(nCol))) trY <- runif(1)*trX[,1]*trX[,2]^2+runif(1)*trX[,3]/trX[,4] trY <-

Hy, I got the following problem when trying to build a rpart model and using everything but LOOCV. Originally, I wanted to used k-fold partitioning, but every partitioning except LOOCV throws the following warning: ---- Warning message: In nominalTrainWorkflow(dat = trainData, info = trainInfo, method = method, : There were missing values in resampled performance measures. ----- Below are some

Dear Help, After loading the pd.Citrus library and checking the DataFrame, I ran > the R code for: > > 1) 'oligo' > > > > {> library(pd.citrus) > Loading required package: RSQLite > Loading required package: DBI > > data(pmSequence) > > > show(pmSequence) > DataFrame with 341730 rows and 2 columns > fid sequence > <integer>

I'm using caret to assess classifier performance (and it's great!). However, I've found that my results differ between R2.* and R3.* - reported accuracies are reduced dramatically. I suspect that a code change to kernlab ksvm may be responsible (see version 5.16-24 here: http://cran.r-project.org/web/packages/caret/news.html). I get very different results between caret_5.15-61 +

Dear useR's, today I stumbled over an interesting phenomenon: First, I created a named numeric vector with a certain class and several attributes via the structure() function. After that, I implemented a simple print method for this class. When calling this function it produces an endless loop of print calls until R crashes. :/ What is going on here? Is this a bug or have I done something

Hello, I am trying to find out how can I generate the smallest R executable. R is to be run in a grid application, in batch mode, so I need a small exceutable, possibly getting rid of any interactive component. Should I look at the embedded version? Any other pointers?

Hello, I'm training a set of data with Caret package using an elastic net (glmnet). Most of the time train works ok, but when the data set grows in size I get the following error: Error en { : task 1 failed - "arguments imply differing number of rows: 9, 10" and several warnings like this one: 1: In eval(expr, envir, enclos) : model fit failed for Resample01 My call to train

Hi, I''m a newbie with Ajax and RJS and have one basic question. When contents in .rjs are exceuted in a Ajax sequence? .rjs seems a kind of alternate for .rhtml view file, so I guess they are in action after the controller action completed. The contents of .rjs file are :complete scenario, right? if so, can''t I write some on :loading action in .rjs? like disabling

I've seen several references on the web to setting up the LDAP SAM to communicate with the LDAP server via ldapi (IPC) verses ldap (IP). This should theoretically much faster. My LDAP master is on the same host as the Samba PDC. With nss_ldap using "uri ldap://localhost" and Samba using "ldapsam:ldap://localhost/" everything works. But changing nss_ldap to use

Hi all, I try to exceute a function "myfun" that should use as input "input1.csv" and "input2.csv" . Then I try to save the output dat33 on a csv file (on per each time I execute input1..input 2 and so on). So my problem is how to finally obtain several csv file with "ggt1.csv", "ggt2.csv". The program creates ggt1.csv but BUT when runs

Is there a way for isolinux/syslinux to execute a list of comboot files immediately at startup, and only once? I have a bunch of small comboot .com files that I want to batch run immediately, then after that do a DISPLAY boot.msg similar in some ways to an autoexec.bat. For example: DEFAULT mycd APPEND ramdisk_size=100000 init=/etc/init lang=us .... TIMEOUT 300 ONSTARTUP mybatch <- ???

Hello all, I have successfully installed xen 3.0.2 on a dual celeron system. Linux in dom0 works fine. Now, I would like to play with the mini-os (my ultimate goal is to implement a small RTOS as guest in Xen, so mini-os looks like an ideal starting point). However, I can''t seem to get it to run as (I think) it should: It boots up, but as far as I understand the source code and the

Dear all, I was willing to use the library "rgl" to plot some 3D graphics, but unfortunately, I wan't able to instal the library. The error message is below.

Hello, I have an p2p voice chat application using WAVE PCM (winmm). Now i am trying to add opus encoding to it to send it over the TCP/IP and then decoding it back to play - but without success (without opus it works ok) Here is an example of my code. I get message from input device then encode with opus then decode it back to output wave header and play. Doing it i hear only noise in my
