【问题标题】:ggplot2: theme_set, pdf export, and Illustrator having difficultiesggplot2:theme_set、pdf 导出和 Illustrator 遇到困难
【发布时间】:2012-10-27 01:56:45
【问题描述】:

我有一个存储为主题的所有主题元素的列表,该主题在绘图之前被唤起。但是,我最近发现当我导出为 pdf 并尝试在 Adob​​e Illustrator 中打开时,我收到一个错误“Acrobat PDF 文件格式有困难”。我还看到 Illustrator 报告说它“操作数太少”。但是,当我使用标准主题(例如,theme_set(theme_gray()))时,Illustrator 没有问题。此外,无论主题如何,我在绘制或保存修改后的数字方面都没有问题。

也许有人可以建议 a) 存储和唤起大量主题设置的最佳方式,以及 b) 可能是我的 ggplot2 -> pdf -> Illustrator 困境的来源。

这是我当前的主题,我如何唤起它,以及一个示例情节。请注意,某些参数已被注释掉,如果我以后需要它们,可以用作占位符。

【问题讨论】:

  • +1 好问题。可能还值得添加您的sessionInfo()
  • size=NA in axis.line = element_line(colour=gridc, size=NA, linetype="solid") 导致问题。如果您不想显示该行,请使用element_blank
  • kohske,发表评论作为答案?

【解决方案1】:

size=NA in axis.line = element_line(colour=gridc, size=NA, linetype="solid") 导致问题。 如果您不想显示该行,请使用element_blank

这可能不是bug,但我建议你在github上提出这个问题:https://github.com/hadley/ggplot2/issues 未来,ggplot2 可能有能力检查参数的有效性。
