...y www directory is owned by "apache" and the group is "todd" and the permissions are 775. My Windows computers use Samba and they log into Linux with "todd". Under the www directory there are various directories which may have a group belonging to a user e.g. "viewpoint". Using this example, there is a directory under www (acutally called httpd), "viewpoint" that is owned by "apache" and is a member of the "viewpoint" group. "todd" is also a member of the "viewpoint" group. Now this is the problem I do...

Dear R-users, within the rgl-package, I would have a question about the usage of persp3d in combination of rgl.viewpoint. I am not able to figure out how to let a 3D plot rotating around likewise the example in ?rgl.viewpoint. It seems that when I use persp3d(...) I see something on my screen, which is different from what I get when it's rotating. Is there any different behavior between shade3d and persp3d? Plea...

Context: I have two or more rgl-based views of a given data set, perhaps fitting different models, or showing different things across views. I want to be able to hand-rotate, zoom, scale one view to something I like, and then show the other views with matching viewpoints and scaling. so that one could flip back/forth among graphs and see only the relevant differences. In 2D, all this usually requires is setting the same xlim, ylim and other constant aspects across multiple graphs. In 3D with rgl, I can do one graph, rotate, zoom, etc. by hand and capture the...

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 ca...

I have read the user reports on the Aastra 480i SIP phones, but the last report is from October, and the advice was to stay away from these units. I was looking at the cisco 79XX series or the SPA-941's, but they don't have backlit displays. I also like POE support so I don't have to run multiple wires to the phones and makes for a neater look. I dislike the looks of the SNOM

This is generally more of a Wine support forum, I guess... Plus you can usually resolve these kind of things with a moderator/admin rather than the whole slew of forum/mailing list users. Note that I know nothing more about this topic than the single post that's shown above...

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

I've been using lattice/wireframe succesfully to visualize some data. I have one question. I want to be able to change the viewpoint ( i.e. rotate the plotted figure a bit left or right or up and down ) Is there a way to do that? Or is there some other package around that could help? Thanks.

...eating the CentOS distribution, while sharing > the same upstream developers as all other Linux distributions. From: Maciej ?enczykowski <maze at cela.pl> > BULLSHIT And so it begins. I think we've all had our say at this point. I can understand (although not agree) with Les' viewpoint. And I'm sure Simon feels like I do, Red Hat doesn't get due credit. But this is why I dislike these "distro contests" in the first place. The are entirely subjective and full of "absolutes" and "versus." Reality is that there is much so much overlap. *** Bec...

...strings, : scan() expected 'a real', got '"1"' Is this really intended? I would have expected that a csv file in which each field is surrounded with double quotes is acceptable in both cases. This may be documented as is yet seems undesirable from both a consistency viewpoint and the viewpoint that it should be possible to double quote fields in a csv file.

I am wondering if anyone knows how to change or rotate the default axes on a 3D scatterplot. I would like to change which sides of the cube the 3 axes are displayed on. Many thanks, Leah Gerber [[alternative HTML version deleted]]

Hi, I pulled compiz from GIT yesterday to see if I could get proper multi-head support. I think the current status is great, but I have one little suggestion to make. The current behavior is that we have two viewpoints of the "cube" (it's more like a body with eight side planes now). If it's rotated one step we skip one of the planes. Rotating four times is enough to go round exactly once. Is it possible to decrease this stepsize, so we can rotate the body in eight steps? I.E. When having two m...

..., so can shell commands, but neither have been > used in anger yet. Ooo. :) Having just had a look at auth_curl.c in kh, that would probably do what we want even better. Is it possible (or would it *be* possible) to make <mount> sections take wildcards for <mount-path>? From our viewpoint it'd be much easier to process whether the user is authorized to handle a *specific* stream in the auth URL, rather than by tweaking icecast.xml every time we add a new stream.

Dear R community (and Duncan more specifically), I can't work out how to make additional light sources work in rgl. Here is the example. First I create a cube and visualize it: > cubo <- cube3d(col="black") > shade3d(cubo) Next I position the viewpoint at theta=0 and phi=30: > view3d(theta=0,phi=30) Next, I want to create a 2nd light source which diffuses red light from the front face. I thought I could do: >light3d(diffuse="red",theta=0,phi=0) but...the front side doesn't show any red-iness. Same goes for specular and amb...

...ed. I need to get rid of phis. This code is compiled from C++ and for some functions there are no phis, but multiple call instructions. I am targeting hardware in the end, and the next tool reading the IR does not like phis when it's generating VHDL. My questions may be somewhat silly from the viewpoint of software compilation for a CPU. Thanks. Teemu

...solution made by llvm-link is a correct operation, which in turn depends on what source language objects are represented in IR. Variables and function must exist in IR because these are entities directly represented in object files, but types do not have similar requirement. There are at least two viewpoints on which entities of source language should be represented in IR. Case 1 LLVM IR is a functional equivalent of the compiled program. It tries to preserve information about externally visible objects (variables, functions) that may be used in operation on IR modules. In particular, as C++ def...

...'m playing with server-side automatic maintenance scripts for things like deleting messages more than x days old from folders a, b, c, etc. (using Maildir layout). So far I'm just zapping files in the cur and new directories and nothing amiss appears to happen from the IMAP client's viewpoint. I just wonder if I'm storing up trouble. Will the index files continue to hold references to non-existent files and get bloated, or do they self-clean? -- Rick Jones -------------- next part -------------- A non-text attachment was scrubbed...
