Hi, I am studying using SVM functions of e1071 package to do prediction, and I found during the training data are "factor" type, then svm.predict() can predict data directly by categories; but if response variables are "numerical", the predicted value from svm will be continuous quantitative numbers, then how can I connect these quantitative numbers to categories? (for

Hi, I tried to add a progress bar to my script, but it seems the "txtProgressBar" function will wipe out what I want to print before it(for example - the "Hello" in following script), and the parameters "title" and "label" do not work either. How can I put a title for the progress bar? or is there any other better function I can use? testit <-

All, I am working with NIR spectral data and it was great to find that the example in ?plsr also used spectral data. Unfortunately, I am having difficulty figuring out how the "yarn" dataset is structured to allow for the plsr model to read: library(pls) data(yard) yarn.oscorespls <- mvr(density ~ NIR, 6, data = yarn, validation = "CV", method = "oscorespls")

I am attempting to create a formula using as.formula for a PLS analysis. I have used the code below successfully, but in a previous R version and with many fewer predictors. Any help getting all of these predictors into one formula would be greatly appreciated. TC.fmla <- as.formula(paste("TC ~ ", paste(vars, collapse= "+"))) As I mentioned, this code worked fine in a

I am attempting to run principal components analysis on a dataset of spectral reflectance (6 decimal places). I imported the data using read.table and there are both column and row headers. When I run princomp I receive the following error: Error in cov.wt(z) : 'x' must contain finite values only Where am I going wrong? Ross

All, I have been using a data set to build pls models for three different soil properties. Two of the three models run fine; however I receive the following error for the final model. > libs.IC.cal <- mvr(libs.IC.fmla, data = libsdata.cond.cal, ncomp=20,validation = "LOO", method = "oscorespls") Error in colMeans(x, n, prod(dn), na.rm) : 'x' must

I am attempting to write a routine where I can run PAM (partition around mediods) on a dataset containing multiple soil cores and PCA spectral data from several depths per core. I want to run PAM on each individual core, so I need to group the data by core to run the analysis. Below is an example of my data structure: Lab.id PC1 PC2 PC3 MAT057.2.5 2.438454966 -1.011182986 -3.040881377

I am new to Linux (not to R) and recently installed Mandriva Spring 2007 on my partitioned hard drive. My next objective is to install R in the Linux environment, unfortunately Mandriva is not one of the Linux distributions available for download... Could someone please let me know which distribution I should use? Thanks. Jonathan --------------------------------- Boardwalk for $500?

Hi, I am trying to read in my Affymetrix CEL files (48 files, total ~600 MB) but I keep getting memory errors. Can somebody please help me with this. Or is therea remote server I can send my data to for computation? Any help is much appreciated.

1. You have levels(A) as "2" and "4", yet you showed equations for A=0 and A=1? 2. y = A + X + A*X means you're allowing the different groups of A to have different slopes. Probably not what you intended. 3. It's probably best to provide a small sample of the data (and R code) so we know how you got what you got. Andy From: Ben Ridenhour > > Hello, >

All, I am a new user to Linux but I am familiar with R. I have previously used and installed R on a Windows platform without problems. I recently set up a dual boot system (XP_64, Mandriva) to run R on a Linux platform in order to more efficiently handle large datasets. I have not done compiling before, but read the R instructions and followed to my best ability. I downloaded the most recent

Hi all: I'm building an authentication infrastructure for combined windows plus linux clients. To that end, I have a Win Server 2008r2 ADS and a win svr 2008r2 client, and an ubuntu 9.10 client running the default samba + winbind (whatever is in their production repos). I had it 95% working this morning...Then all of a sudden, all winbind queries died. No idea why. I spent the entire day

Hi all: I've got a couple Ubuntu 9.10 machines that are suffering from a recurring failure of winbind that essentially crash the machine. When the system is in the "crashed state", one can ping the system, but all forms of login fail. It will not even respond to tftpd requests; ssh connections "time out", but the initial port is opened (just no connect). Rebooting does

Hello, I am new to using R and I am having problems get boot() to work properly. Here is what I am trying to do: I have statistic called "cs". cs takes a data matrix (154 x 5) and calculates 12 different scores for me. cs outputs the data as a vector (12 x 1). cs doesn't really use weights, per se, however I have included this as one of the 2 arguments cs can take. I try

I'm need to run a rsync server on a Quad 2.8Ghz , 1Gb RAM, 1Terabyte of disk.. Dell 725N - it's a storage, NAS type box running W2K, RAID 5 etc.. A real beast.. :-) The Unix guys want to backup their boxes to this beast using rsync clients. It would seem that Windows Services for Unix (WSU) is the key.. Current version gives me a fully compliant POSIX environment, not reliant on

It is my understanding, the alloca memory routines are used for forcing variables to be allocated on the stack frame -- which you would want for source level debugging. When SSA registers are used, LLVM will decide what goes into registers and what will spill over to the stack frame. I want the latter. --w Wayne O.

how to add value on the bar ploted by barplot()? and the axis label is too big, anyone know how to change their font , thanks -- Xiaogang Yang Sensorweb Research Laboratory http://sensorweb.vancouver.wsu.edu/ Washington State University Vancouver [[alternative HTML version deleted]]

This is a simple SSA code generation 101 question. If I follow the IR code generation techniques in the Dragon book the statement x = y + z would translate into something like this in SSA/LLVM %0 = add %y, %z %x = %0 Obviously "copy instructions" like %foo = %bar are senseless in SSA since %foo and %bar are immutably fixed to the same value and there is no need for two aliases

Is there any way to order rich rules in firewalld? If I remove all rules and add them back in firewalld seems to put them in whatever order it feels like. Alternatively, how can I change the default policy of a firewalld zone? At the moment I don't see any way to have a zone accept traffic by default other than adding a rich rule allowing 0.0.0.0/0. -- Jeff White HPC Systems Engineer

The mem2reg pass will rewrite allocas and loads and stores to SSA virtual registers. Essentially it's a transformation from non-SSA to SSA form. That said, I don't know if you want your students to implement their own SSA transformation.
