Hello all, I would like to perform SVM-RFE (Guyon et al. 2002) in R and have only found one implementation of this algorithm. The function belongs to the MCRestimate package but when I try to use it I encounter a problem - the function appears to be missing a required package or other function that I simply cannot find available anywhere. Here is my session info followed by a simple example

After some struggling with the data format, non-standard in BioConductor, I have gotten cor.balance in package CORREP to work. My desire was to obtain maximum-likelihood p-values from the same data object using cor.LRtest, but it appears that this function wants something different, which I can't figure out from the documentation. Briefly, my dataset consists of 36 samples from 12

Anyone have much luck with these on ATA's? I have a few sites that use them succesfully with multi-port Audiocodes boxes, but just connected ten machines to Linksys 2102s and they are very flaky. Using u-law on a 100Mb switched network that is barely utilized, then out a T1 on a Sangoma card. Perhaps there is some tuning on the Linksys or the credit card machine itself? Going to look

OK, I managed to get past this problem. There were two issues - I did not have peth0 configured correctly (as you can see, the ifconfig output does not show a peth0). That was resolved by fixing my settings in the network manager. The second issue was that I don''t have a static IP address, so I selected the option for DHCP on wireless during the guest host setup. I switched to static IP

I'm for not giving accurate information, I am able to create new virtual machines as a non-root user. I have windowsXP and Ubuntu installed on my hard drive as well. So I am trying to create a new virtual machine with custom settings, and using my hard drive, so I can boot windowsXP or Ubuntu while Im in CentOS 5. But when I reach to the end of the settings it tells me I do not have

The Constants for the Styles for FileDialog are not initialized to a value and the class will not work without those, the Dialog will come up when you call the show_modal method but the filenames are not showing up I specifically need the values for FD_OPEN FD_SAVE FD_OVERWRITE_PROMPT FD_FILE_MUST_EXIST but if I can''t get those then I''ll find a workaround so far this has

Hi, We have a proprietary RTOS which is *not* POSIX complaint. We want to port SSH server and SCP client onto our platform. How difficult it would be, to port Dropbear into our platform? We would like to integrate our CLI with the SSH. Any recommendations on using Dropbear for our platform? Appreciate sharing your experiences with Dropbear. --- Thanks, Mohan

Wow, WINE has come so far that I feel (am) old! :) With SafeDisc support, WINE will finally run a LOT of games, too. Currently, I run Papyrus' NASCAR Racing 2002, Payrus' NASCAR Racing 1999 Edition, Novalogic's F-22 Lightning 3 (w/o hardware acceleration), Novalogic's Comanche 4 and various other applications with minimals difficulty. Keep up the great work! It's been a

Hello, I wanted to enable tracing in user process. but following example from guide is not working. pid$1::$2:entry { self->trace = 1; } pid$1::$2:return /self->trace/ { self->trace = 0; } pid$1:::entry, pid$1:::return /self->trace/ { } I am getting error like invalid probe description ..... undefined macro variable in probe description. pid$target:user lib:user function:entry

Hello Again R Folk: I have found items about this in the archives, but I?m still not getting it right. I want to use ggplot2 with facet_grid inside a function with user specified variables, for instance: p <- ggplot(data, aes_string(x = fac1, y = res)) + facet_grid(. ~ fac2) Where data, fac1, fac2 and res are arguments to the function. I have tried p <- ggplot(data,

Hi, after upgrading my R install from 2.5 -> 2.6.1 and performing multiple iterations of update.packages(), I am getting an odd error when trying to plot a calibration curve from the val.prob() function in package Design. when running this function (which used to work) I get the following error message: Error in .C("lowess", x = as.double(xy$x[o]), as.double(xy$y[o]), n,

Hello, When calling several times the svm() function, I get different results. Do I miss something, or is there some random generation in the C library? In this second hypothesis, is it possible to fix an eventual seed? Thank you Pierre ### Example library('e1071') x = rnorm(100) # train set y = rnorm(100) c = runif(100)>0.5 x2 = rnorm(100)# test set y2 = rnorm(100) # learning a

Hi, I was trying to do cross-validation using the crossval function (bootstrap package), with the following code: --------------------------------------------------------------------------------------------------------- theta.fit <- function(x,y){ model <- svm(x,y,kernel = "linear") } theta.predict <- function(fit,x){ prediction <- predict(fit,x)

Hello Again... I?m making a faceted plot of a response on two categorical variables using ggplot2 and having troubles with the coloring. Here is a sample that produces the desired plot: compareCats <- function(data, res, fac1, fac2, colors) { require(ggplot2) p <- ggplot(data, aes(fac1, res)) + facet_grid(. ~ fac2) jit <- position_jitter(width = 0.1) p <- p +

I''m posting this for a friend who is having trouble with this and here is his message. "Heya! I''m working on a script editor application, but it''s missing one key feature: Syntax highlighting. Seeing this, I looked around in the sample directory and came across scintilla.rb. I attempted a run, however Ruby reported Wxruby2::Scintilla as an uninitialized

Dear all, I'm training an SVM with default settings on a matrix csr (SparseM package). I realized that if I train the SVM with the (hopefully) equivalent matrix (Matrix package) representation, the returned models and predictions sometimes differ. I expected both representations of the same data to lead to the same results though. It could be that it is a scaling problem, because unscaled

Hello, My name is Christian Falde. I am new to R. My problem is this. I am attempting to learn R on my own. In so doing I am using some problems from Davidson and MacKinnon Econometric Theory and Methods to do so. This is because I can already do the some of the problems in SAS so I am attempting to rework them using R. Seemed logical to me, now I am stuck and its really bugging me.

Hi R, I wanted to know how do we access the elements of a list. In particular, v=list(c(1,2,3,4,5),c(1,2,33,4,5),c(1,2,333,4,5),c(1,2,3333,4,5)) I want to access all the thirds items of the elements of the list. i.e., I want to access the elements, 3,33,333,3333. This can be done through sapply as: sapply(v,function(x) x[3]) But I need to access this without using
