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

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.

...uments it appears that the basic configuration I would start with is the Two Zone setup. I don''t believe that I have any need at this stage for a DMZ. (I would listen to any advice though!) My questions therefore relate to hardware and the firewall arrangement. 1. I have a spare 486-DX2-66, and a spare Pentium-200MMX both with minimum RAM, as well as a couple of small HDD 450 & 850MB. Which of these would be the better to use as the FW, and how does this FW PC impact on the performance of my small network (basically Pentium 111 PC''s). Or are these PC''s in...

They even have a boot diskette available to support those old BIOS that won't boot CDs, as this unit was. So, thanks Bryan. I'm trying to configure a backup unit on an old Aptiva DX2/66. Have 1 ISA Etherjet. Need a couple more ISA NICS that are configurable for IRQ/IOBASE. Anyone that wants to put two old good ISA NICS into a home where they will be cared for and appreciated, send me an email with details, if config diskette available (even if off the net), price, etc. I...

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 wrapping it to native OpenGL commands probably ? correct?) Can somebody answer that ? I'm very curious, also it may help me write my wine-apps-manager (Yes, I'm trying to write somethi...

The PC is an IBM Aptiva 486 DX2 I've also tried to prepare the HD using a pure Linux alternative.

...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 propagate uncertainty of the points into the uncertainty of the fit, would that be the case?
