我希望rgl
在我的.Rnw
文档中包含动画图表knitr
.这是我的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}
我没有在我的针织文件中得到图表.任何帮助将受到高度赞赏.谢谢
我仍然无法使其工作并收到以下警告:

编辑
更改fig.path = 'figure/'
到fig.path = ''
在opts_chunk$set
编译与文档png
图表但没有任何动画.如果有人指导我如何获得动画rgl
图表,将非常感激fig.path = 'figure/'
.谢谢
我有一个基于你的例子,它在RStudio 0.99.441中使用Windows 8.1上的knitr工作.
这会产生一个40帧的动画.它使用内置hook_plot_custom
函数来包含通过动画3d绘图手动生成的图.动画的代码是基于那些在帮助和来源play3d
和movie3d
.movied3d
本身不能使用,因为它的文件命名太不灵活.
我已经把它放在了https://github.com/NikNakk/testAnimateRgl/上的github上.pdf位于https://github.com/NikNakk/testAnimateRgl/raw/master/rglKnitr.pdf

编辑:新版本
这是另一个版本,它演示了如何使用自定义块选项来设置更简单的参数spin3d
.请注意,对于此版本,块只是一行(scatter3d
图).spin3d.axis
用于将轴参数设置为spin3d
; spin3d.rpm
用于设置rpm
参数.使用标准fig.num
和interval
参数设置图像数量和图像之间的间隔.
