Ich möchte animierte einbindenrgl Grafiken in meinem.Rnw Dokument durchknitr. Hier ist meine MWE:

\documentclass{article}

<< label = setup, include = FALSE>>=
opts_chunk$set(fig.path = 'figure/',  cache = FALSE, dev = "pdf",  fig.align = 'center', fig.show = 'hold', fig.width = 3, fig.height = 3,  echo = TRUE, warning = FALSE, message = FALSE, size = 'footnotesize', comment=NA, results='hold')

knit_hooks$set(par = function(before, options, envir){
if (before && options$fig.show!='none')
 par(mar = c(4, 4, 0.1, 0.1), cex.lab = 0.95, cex.axis = 0.9, mgp = c(2, 0.7, 0), tcl = -0.3)
}
)
knit_hooks$set(rgl = function(before, options, envir) {
  if (!before) {
    ## after a chunk has been evaluated
    if (rgl.cur() == 0) return()  # no active device
    name = paste(options$fig.path, options$label, sep = '')
    rgl.snapshot(paste(name, '.png', sep = ''), fmt = 'png')
    return(paste('\\includegraphics{', name, '}\n', sep = ''))
  }
}
)

options(replace.assign = TRUE, width = 60)
@ 
\begin{document}

<< label=packages >>=
library(car)
@
<< label=rgl1, rgl=TRUE, fig.show='animate' >>=
scatter3d(prestige ~ income + education, data=Duncan)
@

\end{document}

Ich bekomme keine Grafik in meinen gestrickten Dokumenten. Jede Hilfe wird sehr geschätzt. Vielen Dank

Ich kann es immer noch nicht zum Laufen bringen und erhalte die folgende Warnung:

Ändernfig.path = 'figure/' zufig.path = '' imopts_chunk$set Kompiliert das Dokument mitpng Grafiken, aber ohne Animation. Würde mich sehr freuen, wenn mich einige anleiten, wie man animiertrgl Grafiken mitfig.path = 'figure/'. Vielen Dank
