[R-sig-Debian] updating rgl on debian stable

[Michael Friendly]

Running: R Version 2.3.1 (2006-06-01), debian stable

I'm testing an application that uses rgl (installed with apt-get install 
r-cran-rgl)
but fails, at least partly because that application uses a more current 
version.
There is also a mysterious error msg from Xlib:

 > library(car)
 > library(rgl)
 > iris.mod <- lm(cbind(Sepal.Length, Sepal.Width, Petal.Length, 
Petal.Width) ~
+ Species, data=iris)
 > source("heplot.R")
 > source("heplot3d.R")
 > source("pairs.mlm.R")
 > heplot3d(iris.mod)
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
Error in ellipsoid(gmean, E, radius, col = last(col), label = "Error") :
        could not find function "asEuclidean"

Version 2.3.1 (2006-06-01)
i386-pc-linux-gnu

attached base packages:
[1] "methods"   "stats"     "graphics"  "grDevices" "utils"     "datasets"
[7] "base"

other attached packages:
      rgl       car
"0.64-13"   "1.2-0"

If I run example(rgl) alone, things sort of work (I get the volcano data 
displayed),
but I get the same Xlib: message:

 > example(rgl)
rgl> example(rgl.surface)
rgl.sr> data(volcano)
  ...
rgl.sr> rgl.clear()
Xlib:  extension "XFree86-DRI" missing on display ":0.0".

rgl.sr> rgl.surface(x, z, y, color = col)


I obtained the most recent source package for rgl and tried to install it
directly, but this fails.  Any idea what I can do?  How can I tell what X
component is being looked for?

euclid:/tmp# R CMD INSTALL rgl_0.69.tar.gz

Is this what I need?

new modu
