Hi Everyone, I would like to do sequential subtractions within a group so that I know the time between separate observations for a group of individuals. My data: data <- structure(list(group = c("IND1", "IND1", "IND2", "IND2", "IND2", "IND3", "IND4", "IND5", "IND6", "IND6"), date_obs =

Hi all, I have a machine that won't boot syslinux 4.02 but will boot syslinux 3.53. We've installed syslinux 4.02 on a number of machines but only this one has a problem. The problem is that the machine hangs entirely after printing "boot:" on the tty. The stanza being booted in /boot/extlinux.conf is: label xe # XenServer kernel mboot.c32 append /boot/xen.gz

Hello, I am a R beginner and hoping to obtain some hints or suggestions about using permutations to sort a data set I have. Here is an example dataset: Ind1 11 00 12 15 28 Ind2 21 33 22 67 52 Ind3 22 45 21 22 56 Ind4 11 25 74 77 42 Ind5 41 32 67 45 22 This will be read into a variable using read.table. What I want to do is permute these individuals and every

Hi Everyone, I have the following problem: data <- structure(list(prochi = c("IND1", "IND1", "IND1", "IND2", "IND2", "IND2", "IND2", "IND3", "IND4", "IND5"), date_admission = structure(c(6468, 6470, 7063, 9981, 9983, 14186, 14372, 5129, 9767, 11168), class = "Date")), .Names =

Dear R experts, I have a problem with a function I wrote. The fuction looks like this: series<-function(x,s){ foo<-list(); ind3<-integer(); for (j in diff){ for (i in 1:(n-12)){ if (!(x[i,j]==0)&!(x[i+1,j]==0)&!(x[i+2,j]==0)&!(x[i+3,j]==0)&!(x[i+4,j]==0)&!(x[i+5,j]==0)&!(x[i+6,j]==0)

Hi, I am facing a hierarchically structured dataset, and I am not sure of the right way to analyses it with cforest, if their is one. - - BACKGROUND & PROBLEM We are analyzing the behavior of some social birds facing different temperature conditions. The behaviors of the birds were recorder during many sessions of 2 hours. Conditional RF (cforest) are quite useful for this analysis

I have been running a public MySQL server for over 4 years. The system was a 1GHz box with 256MB of RAM. MySQL puts each database into a seperate directory in a single "data" directory. Once the old system reached about 10K databases the connection times increased 10X or more. I attributed the speed problems to a possible filesystem limitation with a large number of files. That

I work with a MySQL installation containing several thousand databases. MySQL represents each database as a seperate sub-directory of the main MySQL data directory. As the number of databases increases it seems that the time to connect is increasing significantly and I believe this is probably due to the time necessary to search through the large number of directory entries. It has been

Greetings Everyone, A group in my office is designing/integrating what I would loosly label as an "embedded system". In that, it performs a dedicated task and is not a general purpose workstation or server. It operates in a harsh environment, particularly a questionable power environment and they are extremely concerned about inadvertent shutdown and recovery. They were totally

Friends Briefly... In the documentation for lda in MASS it describes the value 'scaling' as 'a matrix which transforms observations into discriminint functions...'. How? Verbosely... I have a matrix of data. 9 independent variables and describing 3-classes. About 100 observations in total. A 10x100 matrix of data. I am trying to generate two discriminant functions and i

Hi, When I upgraded my cluster, df started returning some odd numbers for my legacy volumes. Newly created volumes after the upgrade, df works just fine. I have been researching since Monday and have not found any reference to this symptom. "vm-images" is the old legacy volume, "test" is the new one.

HI, I'm trying to have files to be included during rsync. I have the filesystem /stor/circuit_design/, with the following subdirectories as its contents: clock_speed fub_layout test_simulations pattern_flow I would only like to rsync the following 2 subdirectories to the destination machine: clock_speed fub_layout and they're contained in the file called files_included: # cat

OK, seems like there were unused TARGET_MACHO macros that would protect these errors from happening. I made some modifications that add #if TARGET_MACHO.

Dear all, I've got a quite large dataframe (stor) with rows subject and rt (reaction time). I would like to split the reaction times per subject into 6 bins of equal size. Right now, I'm using the following code: bindata <- function(rt) { bindata <- rep(-1,length(rt)) binwidth <- length(rt)/6 bindata[order(rt)[(0*binwidth)+1:(1*binwidth)]] <- 1

Hi everyone, I am using linux/ppc and after porting llvm's jit for this architecture, I am currently trying to compile llvm-gcc on it. I have gcc 4.1.1 and use llvm-gcc from cvs. Compilation fails and the message is: gcc -O2 -DIN_GCC -DDEFAULT_TARGET_MACHINE=\"powerpc-unknown-linux-gnu\" -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long

Hi all, Running into a problem with my gluster here in a LAB env. Production is a slightly different build(distributed replicated with multiple arbiter bricks) and I don't see the same errors...yet. I only seem to have this problem on 2 client vm's that I ran "setfattr -n trusted.io-stats-dump -v output_file_id mount_point" on while trying to test for latency issues. Curious

Hello, I would like for my C function to be able to manipulate some values stored in an R data frame. To achieve this, a need the (real) memory address where the R data frame stores its data (hopefully in a contiguous way). Then, from R, I call the C function and passing this memory address as a parameter. The question: how can we get the memory address of the R data frame? Thank you! L.
