Hello, I installed NUT and configured it for 2 MGE UPS's connected via USB. Debian etch NUT package: # dpkg -l nut*|grep ^ii ii nut 2.0.4-3 The core system of the nut - Network UPS Tools ii nut-usb 2.0.4-4 USB Drivers subsystem for the nut - Network UP Separately, with only one UPS defined in ups.conf, each one works fine (I specified specific serial numbers for either, with

Hi, I'm new to R (and math ;) Would somebody please be so kind as to direct me in plotting a 3D sphere? I tried something in the lines of: #### y <- x <- seq(-pi, pi, length=pi*10) f <- function(x,y) { z <- sqrt(pi - x^2 - y^2) #z[is.na(z)] <- 0 z } z <- outer(x, y, f) persp(x, y, z, theta = 120, phi = 30) #### I've also tried: .... make.surface.grid(...) ..

Dear All, I need to do something simple: I have a set of points which are located on the surface of a sphere (let's say the centre of the sphere is in (0,0,0) and the sphere has radius R=1). How can I visualize them? I am looking for something like this http://bit.ly/PnSerU with the addition of some spots that represent some points I want to plot on the sphere surface. Any suggestion

Dear List, I don't get scatter3d to color the sheres according to the '|' argument. library(car) scatter3d(prestige ~ income + education|type, data=Prestige) The spheres on my screen are all colored the same and they are not conditional on Prestige$type. On the other hand: Fit3d and Ellipse3d are colored according to the group argument. rgl_0.92.879 car_2.0-12 R version 2.15.0

Not an R question directly, but has anyone got a method for placing a moderately large number of (near) equi-spaced points on a sphere? I have a nasty feeling platonic solids are needed for exact solutions and I'm thinking of samplings involving around 200 - 1000 regularly-spaced points, Thanks, Richard Rowe Richard Rowe Senior Lecturer Department of Zoology and Tropical Ecology, James

Hello veryone, I am interested in the diffusion of particles inside a sphere, and its release through a small pore on the sphere surface. Unfortunately, I have not found the way to do this in R. Could you help me? Thank very much in advance for your help

Dears, I've been learning biplot (Gabriel, 1971) and I found the function 'biplot', inside of the package 'stats', useful but, a bit limited. So, I'm thinking to start a colaborative package to enhance this methods to other multivariate methods. In this way, I would like to start it, making public a new function (biplot.pca, still in development, but running) that make

Dear R list I am using rgl.sphere to visualize scatter plot data in three dimensional space. Thanks to the rgl library, I can easily find out the data point that I am interested in. However, as I can not see the labels of each data point directly in RGL window, I usually look for the values of x, y, z axis to find out the label (or line number of the data point). Is there any way that I

I have spatial data on a sphere (the Earth) for which I would like to run an gls model assuming that the errors are autcorrelated, i.e. including a corSpatial correlation in the model specification. In this case the distance metric should be calculated on the sphere, therefore metric = "euclidean" in (for example) corSpher would be incorrect. I would be grateful for help on how to

Dear All, I implemented an algorithm for (uniform) random rotations. In order to test it, I can apply it to a unit vector (0,0,1) in Cartesian coordinates. The result is supposed to be a set of random, uniformly distributed, points on a sphere (not the point of the algorithm, but a way to test it). This is what the points look like when I plot them, but other then eyeballing them, can anyone

Dear list, I'm trying to visualise some ellipsoidal shapes in 3D. Their position, axes, and angular orientation can be arbitrary. I saw an ellipse3d function in rgl; however it is heavily oriented towards the statistical concept of ellipse of confidence, whilst I am just concerned with the geometrical object. Below is my current implementation. It is quite slow when creating many shapes, so

Dear all, I've been learning biplot (Gabriel, 1971) and some days ago I sent for this list a procedural function with invitation for a collaborative package. Jari Oksanen made some suggestions and I agree with all. So, I reworked the function under the object-oriented programming (OOP/S3). I think it is now a good frame for more resources. Below it is the function and a small script to

Dear All, I need to plot some points on the surface of a sphere, but I am not sure about how to proceed to achieve this in R (or if it is suitable for this at all). In any case, I am not looking for really fancy visualizations; for instance you can consider the images between formulae 5 and 6 at http://bit.ly/hOgK9h Any suggestion is appreciated. Cheers Lorenzo

Dear List, I have the code below adapted from the lattice-package examples to draw two spheres. I would now like to give both different surface colors, e.g. one red and one blue. ## 3-D surface parametrized on a 2-D grid n <- 10 tx <- matrix(seq(-pi, pi, length.out = 2*n), 2*n, n) ty <- matrix(seq(-pi, pi, length.out = n) / 2, 2*n, n, byrow = T) xx <-

Hi Gluster Gurus, I'm using a gluster volume as home for our users. The volume is replica 3, running on CentOS 7, gluster version 3.10 (3.10.6-1.el7.x86_64). Clients are running Fedora 26 and also gluster 3.10 (3.10.6-3.fc26.x86_64). During the data backup I got an I/O error on one file. Manually checking for this file on a client confirms this: ls -l

Dear R helpers, I'm trying to write a numerical scheme for a boundary integral method to solve an electromagnetic problem. This requires the computation of the distance between points at the surface of an object (a sphere, in my example). Here is my code, > require(rgl) > r<-1 > size<-10 > theta<-seq(0,2*pi,length=size*2) > phi<-seq(0,pi,length=size) > pc

There's Renka's STRIPACK, and TRIPACK, respectively, ACM TOMS Algorithms 772 and 751, and there's the R package "deldir" which does the Delaunay for a plane, but does anyone have or know of the tessellation in R for a sphere? Also, is there a standard indexing scheme for Delaunay facets, and perhaps of edges in such facets? I'd expect that to be a publication reference,

Hi Richard, Thanks for the informations. As you said there is gfid mismatch for the file. On brick-1 & brick-2 the gfids are same & on brick-3 the gfid is different. This is not considered as split-brain because we have two good copies here. Gluster 3.10 does not have a method to resolve this situation other than the manual intervention [1]. Basically what you need to do is remove the

Thanks for this report. This week many of the developers are at Gluster Summit in Prague, will be checking this and respond next week. Hope that's fine.
