r - 在 Mac 上包含 cairo R

Question

我正在尝试在 Rstudio 中使用“Cairo”包，使用命令 install.packages('Cairo')一切顺利。我收到这条消息 -

The downloaded binary packages are in
/var/folders/xn/c1nj85gx62b89876s15sbv9h0000gn/T//RtmpK9JM0l/downloaded_packages 

该包出现在包列表中，但是当我尝试使用 library(Cairo) 或 library('Cairo') 包含该包时我收到此错误消息-

Error : .onLoad failed in loadNamespace() for 'Cairo', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.3/Resources/library/Cairo/libs/Cairo.so':

我不知道为什么会发生这种情况，有什么帮助吗？谢谢!

您应该下载 X11 for Mac，称为 XQuartz。它不再随 OS X 一起提供，因此您必须从以下位置单独下载:https://www.xquartz.org/
