Greetings: I've searched the R archives with no luck. I want to print this to the screen as part of on-screen instructions as an example: default.FACTOR.labels <- c("Probe1", "Probe2", "Probe3") I can't seem to trick gsub() gsub("'", "\"", "default.FACTOR.labels <- c('Probe1', 'Probe2',

Hi, I have been trying out a nice new tws controller and decided to enable debugging in the kernel and run some stress tests. With a regular GENERIC kernel, it boots up fine. But with debugging, it panics on boot. Anyone know whats up ? Is this something that should be sent directly to LSI ? pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0

Can someone show me some code to do normalization by the median of some control genes for the example below? Many Many Thanks in advance This strategy selects a subset of genes (called ?control genes?) and makes the median of their data distribution similar across arrays. ??? ??? id1??? id2??? id3 control1??? 0.8??? 0.7??? 0.6 control2??? 0.6??? 0.2??? 0.4 probe1??? ??? 0.3??? 0.2??? 0.5

Does an R package exist that is similar to SAS/Intrnet (http://support.sas.com/documentation/onlinedoc/intrnet/index.html) that will allow users to take parameters passed to it by a web request, produce results and return them to the web-browser in HTML format?  I tried looking through the package descriptions, but didnt' see anything like this.  Any direction or suggestions you could provide

Hi, i have two files (file1.txt and file2.txt) which i would like to merge, based on certain criteria, i.e. it combines data based on matching geneID and exons. i have used the merge option, but it does not give me the desired outcome. merged.txt shows the result i would like. *File1. txt* ** AffyProbe ProbeType Flag GeneSymbol GeneID Exons Chrom Strand Affytart AffyEnd 1

I'm using R0.90.1 on Win98. I'm trying to load an image I saved yesterday but I keep getting the following error: Error in load("C:/temp/245amData.R.RDa") : restore file corrupted -- no data loaded The image is 4,890KB. The image Can anyone tell me how to solve this problem? I'm sure I saved the image correctly. Thanks. Mark Mark J. Lamias Department of Statistics

Thomas, Have spoken to Soren, from my bootlog he believes that the problem is in atapicam causing the system to lock up. He is happy to answer some questions but doesnt have time to delve into atapicam himself. Did you author atapicam, I have seen your name on the sourcecode, can you help me further? Whats next? Thanks Adam. -------------- next part -------------- An embedded message was

A problem with 4.8 reported by myself and Aaron D. Gifford. Anyone in -stable who knows more? ******** I'm assembling a Compaq 1850R with attached storage system. For the built in scsi controller (sym), there are three drives internally on channel 1 + 5 drives externally on channel 2. During boot, I can see all disks being identified first by the machine itself and then in the early part

Hi, I am trying to convert a colleague from using SPSS to R, but am having trouble generating a result that is similar enough to a bootstrapped cox regression analysis that was run in SPSS. I tried unsuccessfully with bootcens, but have had some success with the bootcov function in the rms package, which at least generates confidence intervals similar to what is observed in SPSS. However, the

I wish to create a matrix of all possible percentages with two decimal place percision. I then want each row to sum to 100%. I started with the code below with the intent to then subset the data based on the row sum. This works great for 2 or 3 columns, but if I try 4 or more columns the number of rows become to large. I would like to find a way to break it down into some kind of for loop, so

D'oh! I've been using cat() but somehow never got the bigger picture. Thanks!!! Charles Annis, P.E.

I am trying to graph two planes on the same graph using persp(). I can only get one plane to plot at a time. Can someone explain how I can graph two planes on the same graph using persp? I've looked throught the documentation, but cannot find any references to appending a persp plot. Thanks. Sincerely yours, Mark J. Lamias Statistical Consultant

Does anyone have a piece of code or know how I can use R to generate a table of critical values for the Mann-Whitney (aka Wilcoxon Rank Sum) test. Ideally, I'd like a table that contains the critical values for any two samples of size 3 through 30. I could use Monte Carlo simulation or the normal approximation when n1 and n2 are greater than, 10, but I figured someone may know how to

Full_Name: Mark J. Lamias Version: 1.7.0 OS: Windows 2000 Pro Submission from: (NULL) (65.222.84.72) I am running the qwilcox procedure and it is producing incorrect results. For example, dwilcox(.025, 3, 5) should equal 6, but it is equal to 1. Similarly, dwilcox(.025, 3, 6) should equal 7, but it equals 2. The critical values are not set being returned with the correct values. I've

Well, this question comes once and again. I have RC3 and Garf's RC2 tuned versions (160 and 350) in a nice graph. Nobody should be surprised that RC3 is better, but in some cases GRC2 shows better EAQUAL/bitrate results. There seems to be room for improvement in RC3 with some tweaking. See it by yourself at http://audio.sinderman.com/ Cheers, AGS.

Hello! I am getting the following errors when running optim() [I tried optim() with 3 different methods as you can see]: Error in optim(c(0.66, 0.999, 0.064), pe, NULL, method = "L-BFGS-B") : objective function in optim evaluates to length 6 not 1 > out <- optim( c(0.66, 0.999, 0.064), pe, NULL, method = "Nelder-Mead") Error in optim(c(0.66, 0.999, 0.064),

I'm trying to improve the setup of our Dovecot/Exim mail servers to handle the increasingly huge accounts (everybody thinks it's like infinitely growing storage like gmail and stores everything forever in their email accounts) by changing from Maildir to mdbox, and to take advantage of offloading older emails to alternative networked storage nodes. The question now is whether having a

Hello! I am trying to write a function with vector and data.frame parameters that uses the sum() function and values from the rows of the data.frame. I need to pass this function as a parameter to optim(). My starting point is: observs <- data.frame(y, x1, x2, x3) Fn <- function(par, observs) { sum( (y - (par[1] * (x1 + 1) * x2^(-par[2]) * x3^par[3])^2 ) }

Is there anyone who can run .Net Framework 2.0 with the stable kernel 2.6.34 or 2.6.35? I can successfully install dotnet2 both with kernel 2.6.33 and 2.6.35, but can only run it when booting into kernel 2.6.33. With kernel 2.6.35 I don't have the permission as user to run dotnet2, and get an access denied. An example: Running AGS (Adventure Game Studio) with kernel 2.6.33 works fine. But
