linux - Recompile R with PNG support

Question

I am running R 3.1.2 on a headless Raspberry Pi 2 with Raspbian. Packages install fine, but I can't save PNGs. After googling the error for a long time, I found this response, which says I need to "manually recompile R with explicit PNG support."

I apologize if this is a basic question, but how do I recompile R with PNG support? If it's helpful, this is how I installed in the first place. Thanks in advance!

Answer 1

说什么capabilities()["png"]？我怀疑它说TRUE，因为我认为您的 Raspian 软件包不应该遵循 R 源默认值和 Debian 软件包默认值的标准配置。

Answer 2

感谢@Dirk，他正确地将其诊断为在 pi 上无头运行 R 的问题，我通过混合以前帖子的答案找到了解决方案：

• 我通过调用启动 Rxvfb-run --server-args="-screen 0 1024x768x24" sudo R
• 我在 R 中安装了这个Cairo包，并使用我改编自这篇博文的代码保存了绘图
