On OSX and Linux, the rgl package currently requires X11 libs to be available for linking. Recent versions of OSX don't include them by default, so I'd like rgl to fail nicely. Ideally, it will load a library that doesn't need to link to the X11 libs but will still allow WebGL code to work, but that's complicated, so I'd like a stopgap. I can detect that the failure is

FYI, one platform where I have not been able to get interactive rgl working is iOS 8. iOS 8 is supposed to support WebGL, and Javascript is enabled.

Hello, The recently created online "rgl Overview" at https://cran.r-project.org/web/packages/rgl/vignettes/rgl.html illustrates a problem that I am trying to resolve. At the bottom of each image block on that page appears the advisory: You must enable Javascript to view this page properly. I am using Safari under MacOS with Javascript and WebGL both enabled, so it must be the

If I recall it correctly, at least on Linux, rgl only needs X11 when rgl.useNULL(FALSE). Is that correct? If so, I would say dependency on X11 is optional and therefore you should be able to load the package even without X11. Or is it that it still requires X11 libs but not an X11 server?

Hi, I am trying to install a package (PortfolioAnalytics) of R 2.15.2 on Win 7. I have tried the following instructions on : http://stackoverflow.com/questions/11105131/cannot-install-r-forge-package-using-install-packages I used svn checkout svn://svn.r-forge.r-project.org/svnroot/returnanalytics/ to get the package and then copy it to my Win 7. Then, on Win 7 I run: >

I saw that in rgl:::writeWebGL that "Polygons will only be rendered as filled; there is no support in WebGL for wireframe or point rendering.". I found that you can easily use contour3d to make reproducible contour web figures, such as (taken from contour3d help) library(AnalyzeFMRI) a <- f.read.analyze.volume(system.file("example.img", package=

I'm relieved to read that this issue is becoming more visible. In my own work on optimizers, I've been finding it awkward to provide a clean solution to allowing users to run e.g., optimx, when some optimizers are not installed. Unfortunately, I've not found what I consider to be a solution with any elegance. JN On 15-10-23 06:00 AM, r-devel-request at r-project.org wrote: >

Dear list members, I'm encountering the following problem with package dependencies and imports: The Rcmdr package doesn't declare a formal dependency (via depends or suggests in the package DESCRIPTION) on the rgl package because the latter apparently causes problems on some systems. This allows the Rcmdr package to build and check on systems without rgl present; if rgl isn't

Dear List, In one of my packages I have an S3 method for the plot3d generic function from package rgl.

Note that I importFrom(rgl, plotd3d) and register my S3 method via S3Method() in the NAMESPACE. If rgl is not in
