[R] Pb encountered with demos

[Naji]

Hi all,


I've just installed R on my Mac & PC.
The base demo run fine.. But I'm encountering several pb with some packages
(installed using CRAN binaries using the menu)
- Lattice:
> demo(lattice,package='lattice')

    demo(lattice)
    ---- ~~~~~~~
Type  <Return>     to start :
> require(grid)
[1] TRUE
> old.prompt <- grid.prompt(TRUE)
> old.settings <- trellis.par.get()
Erreur dans eval.with.vis(expr, envir, enclos) :
    impossible de trouver la fonction "trellis.par.get"
- Zelig
> demo(poisson,package='Zelig')
    demo(poisson)
    ---- ~~~~~~~
Type  <Return>     to start :
> data(sanction)
> user.prompt()
Erreur dans eval.with.vis(expr, envir, enclos) :
    impossible de trouver la fonction "user.prompt"
De plus : Warning message:
data set 'sanction' not found in: data(sanction)

Is there something wrong in the settings?
Thanks helping me to fix this
