similar to: rgl how to plot a cylinder like arrow3d?

Hi, I am looking for a package which allows me to draw arrows (cylinders with cones on them, basically) in 3d images produced with rgl. Is such a thing available? I did notice the 'compositions' package, which contains 'arrow3D'. However, it relies on 'tensorA', which fails to install on my machine with the error message copied below. If anyone can help me fix this

For a paper dealing with generalized ellipsoids, I want to illustrate in 3D an ellipsoid that is unbounded in one dimension, having the shape of an infinite cylinder along, say, z, but whose cross-section in (x,y) is an ellipse, say, given by the 2x2 matrix cov(x,y). I've looked at rgl:::cylinder3d, but don't see any way to make it accomplish this. Does anyone have any ideas? thx,

Hola a todos: Estoy intentando visualizar unos resultados de un programa en R de forma dinámica. Dichos resultados se pueden representar, básicamente, con un plano que gira sobre uno de sus ejes: para dar sensación de movimiento he utilizado la función rgl.clear(), ya que no encuentro los equivalentes en rgl de los parámetros add o new. El problema es que al limpiar la pantalla con rgl.clear la

Hello R-users, I have downloaded and installed a binary version for Windows OS of ImageMagick (ImageMagick6.5.6-10-q16-windows-dll.exe), I have installed the rgl package and i've tried running the following example from ?movie3d() library(rgl) open3d() plot3d( cube3d(col="green") ) M <- par3d("userMatrix") play3d( par3dinterp( userMatrix=list(M,

Hi all, I am considering writing a 3D visualisation package for R. Purposes: - Visualise 3 dimension data - Manipulate the data or series or any other object with the mouse as in any 3D software (3D Studio Max, Lightwave...) - Eventually display more than just 3D objects. Justification: - It's always interesting to plot data before performing any analysis - Manipulating (rotating,

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

Hello, I want to draw 3D cylinder objects in R. Given is the length and the diameter of the cylinder. Has anybody an example? Thank you very much!

Hi All, I'm using 'tck' option to *reduce* the length of tick marks but it is not working, can anyone please tell me where I'm going wrong... require(graphics) require(grDevices) x <- seq(-10, 10, length= 30) y <- x f <- function(x,y) { r <- sqrt(x^2+y^2); 10 * sin(r)/r } z <- outer(x, y, f) z[is.na(z)] <- 1 # 'bg' works but 'tck' is not showing

I've just released the latest R-Forge versions of heplots 0.9-3 and candisc 0.5-18 to CRAN. They should appear there within a day or two. == heplots The heplots package provides functions for visualizing hypothesis tests in multivariate linear models (MANOVA, multivariate multiple regression, MANCOVA, etc.). They represent sums-of-squares-and-products matrices for linear hypotheses and for

Hi All, I would like to be able to use play3d() to translate the view along a surface, and zoom in and out. All the examples in play3d() function description are of rotations. I would also like to know if there is a method of creating a legend of for the 3d surface using rgl package. Thanks in advance. Chibisi [[alternative HTML version deleted]]

Is there a way to change the viewpoint using view3d (or rgl.viewpoint) with respect to the image that currently appears rather than the perspective that rgl thinks is the default? For example, if I create an image and then perform what should be a no-op: rgl.viewpoint(userMatrix=rotationMatrix(0,1,0,0)) the image is rotated. Then I can perform rotations on the result without surprises. But I

Dear all, I would like to draw a 3-D horizontal cylinder preferably in RGL device (because this gives the look from different angles). Basic idea is from http://www.tau.ac.il/cc/pages/docs/sas8/insight/chap18/sect3.htm. Below is the description exactly what I want to do. Please see at figure 18.6, 1st plot. Here it is an confidence ellipsoid. Suppose now you put another 4 same ellipsoids on top

Dear all, I need your advice since I am looking for an implementation of the parabolic cylinder function in R. I found implemantations of the hypergemetric functions (the Whittaker and the confluent hypogeometric functions) in the package fAsianOptions but the parabolic cylinder function was unfortunately not there. Do you know of such implementation? Thank you very much for your advice.

Hi, I created a 4 Meg Byte primanry DOS patition onto a hard disk. This partition was formatted with format /s. The hard drive was able to boot DOS. After that I connected the drive to a Linux machine and created and image with the command dd if=/dev/had1 of=hard.img When I send this image to my PXE client I see on the screen: MEMLINUX: Image seems to have fractional end cylinder MEMLINUX:

Running CentOS 6.3 Areca hardware raid 10 fdisk -l reports multiple partitions with the following description. "Partition # does not end on cylinder boundary." Disks are 512 byte sector size. Raid stripe size is 64K. but if I use fdisk -lc (-c Switch off DOS-compatible mode. ) I don't get any warnings. Should I reinstall? (performance hit?) -- Robert Arkiletian Eric

Hi, it was brought to my attention that sfdisk has lost the ability to deal with C/H/S addressing as of util-linux 2.26, so the -C ,-H, -S command line parameters are no longer supported. Should there be a compile-time check based on "sfdisk -h" output that would cause daemon/sfdisk.c to be compiled only if something like the following is present? ,---- | Override the detected geometry
