[R] rgl_081.708: rgl.snapshot fails, causing persistent problems
*Summary*: The latest Windows binary version of rgl_081.708 from
R-Forge has some problem that
causes rgl.snapshot() to fail, at least on my system.
Thereafter, *all* rgl 3D graphics are rendered without any text labels.
The last problem remains even after (a) removing rgl and re-installing
from CRAN, (b) re-starting
with a fresh installation of all of R 2.7.2.
*System*: Win XP Pro
A vexing and persistent problem arose after I installed rgl_081.708 from
R-Forge via
install.packages("rgl",repos="http://R-Forge.R-project.org")
Everything worked fine until the *first* time I tried to take a
rgl.snapshot() of the current
scene.
> rgl.snapshot("test.png")
[1] "failed"
OK, I did :
remove.packages("rgl")
install.packages("rgl")
to get rgl_081 from CRAN
However, after that, snapshot works, but all rgl.text -- axis labels,
tick labels, plot
annotations, etc. do not appear.
E.g.: see
http://euclid.psych.yorku.ca/SCS/Gallery/Test/iris3d-bad.jpg
produced by:
library(rgl)
data(iris)
col <-c("blue", "green", "red")[iris$Species]
plot3d(iris[,1:3], type="s", size=0.4, col=col, cex=2, box=FALSE,
aspect="iso")
(There should be variable labels and tick labels for the axes.)
I've now tried everything I can think of, *both* with R 2.7.2 and R 2.7.1
- quitting and restarting R
- uninstalling R, and re-installing a fresh copy, with all my old
libraries (rgl_081)
- reboot and power-down/restart
The problem persists, and I don't know what to look for to try to track
this down
and fix it. Some questions:
What might cause this to persist, even after reinstalling R?
Could there be any interaction between rgl.dll and anything else on my
system?
Is anyone brave enough to see if this problem [with rgl_081.708] is
reproducible?
If not reproducible, then it is something on my system. If it is, could
there be
a problem with the build process on R-Forge for building rgl with png
support?
I've contacted the package maintainer, but he has no suggestions.

[R] rgl_081.708: rgl.snapshot fails, causing persistent problems
Dear Michael, I haven't tried rgl.snapshot() in the development version of rgl, so I can't comment on that, but I believe that these are two unrelated problems. I think that the version of rgl on CRAN fails to display text when rgl.* and *3d function calls are mixed, while this works in the development version. I hope this helps, John> -----Original Message----- > From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org]On> Behalf Of Michael Friendly > Sent: October-08-08 10:54 AM > To: R-Help > Subject: [R] rgl_081.708: rgl.snapshot fails, causing persistent problems > > *Summary*: The latest Windows binary version of rgl_081.708 from > R-Forge has some problem that > causes rgl.snapshot() to fail, at least on my system. > Thereafter, *all* rgl 3D graphics are rendered without any text labels. > The last problem remains even after (a) removing rgl and re-installing > from CRAN, (b) re-starting > with a fresh installation of all of R 2.7.2. > *System*: Win XP Pro > > A vexing and persistent problem arose after I installed rgl_081.708 from > R-Forge via > install.packages("rgl",repos="http://R-Forge.R-project.org") > > Everything worked fine until the *first* time I tried to take a > rgl.snapshot() of the current > scene. > > rgl.snapshot("test.png") > [1] "failed" > > OK, I did : > remove.packages("rgl") > install.packages("rgl") > to get rgl_081 from CRAN > > However, after that, snapshot works, but all rgl.text -- axis labels, > tick labels, plot > annotations, etc. do not appear. > E.g.: see > http://euclid.psych.yorku.ca/SCS/Gallery/Test/iris3d-bad.jpg > produced by: > > library(rgl) > data(iris) > col <-c("blue", "green", "red")[iris$Species] > plot3d(iris[,1:3], type="s", size=0.4, col=col, cex=2, box=FALSE, > aspect="iso") > (There should be variable labels and tick labels for the axes.) > > I've now tried everything I can think of, *both* with R 2.7.2 and R 2.7.1 > - quitting and restarting R > - uninstalling R, and re-installing a fresh copy, with all my old > libraries (rgl_081) > - reboot and power-down/restart > > The problem persists, and I don't know what to look for to try to track > this down > and fix it.
