安装JGR时出现问题

Question

我一直在尝试安装JGR，但没有成功。当我尝试时，我得到了下面发布的错误。我已经尝试使用JGR-1.6-SL.dmg以及通过R终端进行安装。这似乎是一个java问题，但我不确定如何解决它。

这是我的系统信息：

OSX 10.7.2
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)
R version 2.14.1 (2011-12-22)  (Installed with homebrew)

错误：

* installing *source* package ‘iplots’ ...
** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices ...
** testing if installed package can be loaded
Note: On Mac OS X we strongly recommend using iplots from within JGR.
Proceed at your own risk as iplots cannot resolve potential ev.loop deadlocks.
'Yes' is assumed for all dialogs as they cannot be shown without a deadlock,
also ievent.wait() is disabled.

任何帮助都将不胜感激。谢谢。

Answer 1

如果你从homebrew安装R，R是从源代码编译的。要在出现此错误的位置安装类似iplots的内容，需要从R控制台使用以下命令：

Sys.setenv(NOAWT=1)

您可能需要删除此后记，在这种情况下，您可以使用以下命令：

Sys.unsetenv("NOAWT")

Answer 2

在您的OS版本上，如果您想要从源代码(例如，通过使用NOAWT=1 R CMD INSTALL ..)编译iplots和JGR包，则需要设置NOAWT=1。
