Dear all, The following problem just has been submitted to me by an accountant. In his new job, he has to close some old accounts. He has yearly amounts, and a list of products that have been bought over the years, at certain prices for which he has an exhaustive record. The problem is: He does not know what product was bought this or that year (don't ask). He does not want to find back

Hello, it''s not the first time but ... Who know? Well, I use xen in HVM. All works fine, my keyboard in Dom0 is AZERTY, but this keyboard become QWERTY when i enter in VM, it''s not useful to type password. How can i keep my keyboard AZERTY in my VM and in Dom0? -- Benjamin HENRION Elève de 4eme année de l'' EXIA (Nancy) Ecole supérieure d''informatique Spé

Hi, Since a week or two I can''t create two of my three WinXP DomU''s anymore, the third one starts just fine. This is the basic error message I get: # xm create WinXPViaLilaGeert Using config file "./WinXPViaLilaGeert". Error: Creating domain failed: name=WinXPViaLilaGeert There is little information in this error message. /var/log/xen/xend.log has a little more:

Hola! I am programming a class (S3) "symarray" for storing the results of functions symmetric in its k arguments. Intended use is for association indices for more than two variables, for instance coresistivity against antibiotics. There is one programming problem I haven't solved, making an inverse of the index function indx() --- se code below. It could for instance return the

Hi, First my apologies for a non-working piece of code in a previous submission, I have corrected this error. I'm doing is individual based modelling of a pathogen and it's host. The way I've thought of doing this is with two dataframes, one of the pathogen and it's genes and effector genes, and one of the host and it's resistance genes. During the simulation, these things

Several of the methods I use for analyzing large data sets, such as WinGamma: determining the level of noise in data Relief-F: estimating the influence of variables depend on finding the k nearest neighbors of a point in a data frame or matrix efficiently. (For large data sets it is not feasible to compute the 'dist' matrix anyway.) Seeing the proposed solution to "[R] distance

Hi, Sometimes I need to consult the history of commands that are matching a regex, so I modified the utils::history function for that purpose. I found it useful. I append the code ( I only added the two lines with #**) Romain. history2 <- function (pattern="", max.show = 25, reverse = FALSE, unique = pattern!="", ...) { file1 <- tempfile("Rrawhist")

Hi all, I have a list of genes present in 500 individuals, the individuals are the elements: Genes <- lapply(1:nrow(inds),function(x) sample(1:10000,inds$No_of_Genes,replace=TRUE)) (This was later written to a dataframe as well as kept as the list object: inds2 <- data.frame(inds,Genes=I(Genes))) I also have a vector of how many of those genes are expressed in the individuals, this can

Why would R lack history capability? Someone in a private electronic mail message suggested the possibility that I was running R in a non-writable directory.

Hi all, Dear Dr. Wheeler, I am trying to use the lmPerm package to perform multiple regression on microarray data with certain empirical variables associated with treatments of the experiment. In order the circumvent the very conservative multiple test corrections such as Bonferroni and BH, I try to use permutated probabilities to assess associations. In addition to mu previous posting I

Hi, I''m on a HP DL365, amd64, running SLES10sp1, but with kernel and xen of SLES10sp2, therefore using Xen 3.2. The domU shall be a Windows HVM guest. I want use the Qlogic SAN card in a domU. I''m following these instructions: http://www.novell.com/communities/node/2880/assign-dedicated-network-card-or-pci-device-xen-virtual-machine well, there is written that this only

I wrote a function which does "moving window" regressions. E.g. if there are 100 observations and the window width is 50, then I first run the regression for observations 1..50, then for 2..51, and so on. I am extremely pleased with R in my experience with writing this, since I was able to pass the model as an argument into the function :-) Forgive me if I sound naive, but that's

Hello, I'm attempting to create a data frame with correlations between every pair of variables in a data frame, so that I can then sort by the value of the correlation coefficient and see which pairs of variables are most strongly correlated. The sm2vec function in the corpcor library works very nicely as shown here: library(Hmisc) library(corpcor) # Create example data x1 = runif(50) x2 =

Hi, I'm trying to take a function from a workspace download provided in a stats textbook book, so I have it in my workspace to use all the time. I opened the workspace and typed the names of the two functions to get the code that makes them up: ------------------------------------------------------------------------------------- > resample function(d, size,

Hello list I have a problem with a dataset (see toy example below) where I am trying to find the difference between two (or more numbers) and discard those observations which fall outside a set interval.

Greetings R users! I am working with the ENSEMBLE climate data (10 min resolution daily temperatures images for all of Europe 1950-2006). The data comes packaged in a single netCDF file. I would like to read the data in and export a subset (2002-2006) as geotiffs (one image per day). So far, I can successfully read in the data and view the images within an R display window. However, I have yet to
