[R] rgl-snapshot failed (err-msg: "failed")

[Oliver Bandel]

Hello,


I tried to use rgl.snapshot and it failed.

The error message was not very verbose:



======================
>
>
> plot3d( motion[[idx+2]], motion[[idx+1]], motion[[idx]] )
> rgl.snapshot(filename="/tmp/shot_01.png", fmt="png")
[1] "failed"
>

======================

There was a graphic created by rgl, but the snapshot was
not created.

The same problem occurs, when I use
    > example(rgl.snapshot)

The graphic/animation will be created, but there is no possibility
to create the output-files.

I use "R version 2.4.0 Patched (2006-11-25 r39997)".
Is this a problem of this old version? or is there
maybe a general problem, independent of the version?

Any ideas?


Best,
   oliver
