Using the input below, can I do something more elegant (and more efficient) than the loop also listed below to pad strings to a width of 5? The true matrix is about 300K rows and 31 columns. ####################### #INPUT ####################### > temp DX1 DX2 DX3 1 13761 8125 49178 2 63371 v75 22237 3 51745 77703 93500 4 64081 32826 v72 5 78477 43828 87645 >

Hi, I am having a problem with a very slow indexing and sub-sectioning of a 3d array: > dim(arr) [1] 245 175 150 For each point in the array, I am trying to calculate the mean of the values in its surrounding: mean( arr[ (i - radius):(i + radius), (j - radius):(j + radius), (k - radius):(k + radius)] ) Putting that code in 3

Hello, I am writing a package with a collection of several models. In order to allow users to play interactively with the models (in contrast to hacking lengthy scripts), I want to put all what is needed to run a particular model into a single list object for each model. Then there will be a collection of functions to run the model or to modify parameters, time steps, integration method ...,

Dear R-users, I've a question regardiing multiple linear regression. Is it possible to regress a function of the type y=b0+b1*x1+b2*x2 constraining the partial derivatives dy/dx1 and dy/dx2 to be greater than 0 ??? Thank you very much for any possible suggestion.

I'm looking for an extension of kappa to measure agreement among multiple raters when there can be more than one response per subject. For example, say a group of doctors assign diseases to patients. Each patient will be assigned one to many diseases, and the number of doctors assigning diseases to any one patient will be two to many. Here's an extremely simple example of the type of

Hello, I have 2d data where x coordinate is not given in usual ascending order (x1,...,x1+l; l>0), and instead in another, regular, but not ascending or descending order (for illustration: x1,-x1,x1+dx1,-x1-dx1,....).y is an array which corresponds to the way x is ordered. I have noticed that giving 'plot(x,y,type='l') produces a plot where the points are connected in a completely

A few weeks back I had tried to install CentOS on my old AMD 5x6x (equiv to P75 performance) with plans to use it as my firewall and router. Because there were some problems relating to RPM compile architecture (apparently), I posted and Bryan suggested IPCop, even at peril to his life on these lists ;-) according to him. ;-) ;-) Just wanted to tell him thanks, it's worked out well. Had

I am quite new to Linux and have moved (almost) from a windoze NT4 environment. My present configuration is running SuSE V 8.0 with KDE3.0.5 desktop on two machines, connecting with Samba to an NT4 PC, and an occasional laptop or other PC that connects locally to the network. After a deal of searching, researching, and seeking advice I have decided to use Shorewall as my firewall.

Hello again. Today I got following questions: 1.Which version of OpenGL is wine written in? 3.1? 3.0? 2.1? 2.0? Lower maybe? 2.Is wine using custom OpenGL extensions? From which vendors (NVIDIA I guess, ATI, S3, INTEL or others as well?)? 3.What is the minimum OpenGL version to run DX2/3/6/7,DX8,DX8.1 and DX9.0 apps? (I guess for OpenGL apps it doesn't really matter right? You are just

Hi, I've made several attempts to boot syslinux from the harddisk. I have a win 98 startdiskette with syslinux and copybs. I strictly follow the procedure in the syslinux documentation. Yet, the result of the boot is not that linux is starting. Instead, the Microsoft windows screen flashes for a couple of seconds and is then replaced by a Dos prompt. Syslinux is V2.04. The PC is an IBM Aptiva

Im using arch linux 64bit, and i am unable to run ImgBurn properly..... it just displays an error message saying that the program cannot start and that's it. Does anyone around here use ImgBurn as i do? How did you manage to make it work? Thank you!!! Wine version: 1.3.30 ImgBurn Version: 2.5.6.0

As this forum proved to be very helpful, I got another question... I'd like to fit data points on which I have an error, dx and dy, on each x and y. What would be the common procedure to fit this data by a linear model taking into account uncertainty on each point? Would weighting each point by 1/sqrt(dx2+dy2) (and taking dx and dy as relative errors) in a lm() fit do the job? I would like to

The nbdkit tests take a long time to run especially on armv7. To try to get an idea of which tests take the most time, and since I happen to have a qemu aarch64 *TCG* guest available, I ran the tests on that guest. A TCG guest is about the worst case for libguestfs, used by some tests, since it uses double-nested TCG, and as you can see below there are tests taking over 6 hours. In fact I

I'm getting samba setup, and it seems to be working. I have PDC/BackupPDC issues to resolve, and want to change things so the NT PDC authenticates users instead of setting them up using smbpasswd. Right now, I can access the samba box from Win98 and WinNT workstation with "manually setup" smbpasswd's. I have been testing performance and am a little disappointed, I hoped samba

Hi, I am doing a project on the simulation of glucose metabolism based on a pharmacokinetic modeling in which we have 4 differential equations. I did this in R by using the odesolve package.
