Mac OS X Yosemite中的NetLogo R扩展安装错误 [英] NetLogo R Extension Installation Error in Mac OS X Yosemite

问题描述

我在安装NetLogo的R扩展时遇到问题。我正在使用NetLogo 5.05和扩展版本1.3，它应该适用于R 3.0或更高版本。我的R版本是3.1.2。

I am having problems installing the R extension for NetLogo. I'm using NetLogo 5.05 and version 1.3 of the extension, which is supposed to work with R version 3.0 or higher. My version of R is 3.1.2.

按照页面，我更改了NetLogo应用程序中的.plist文件，使其指向jri和我的R安装：

Following the instructions from this page, I have changed the .plist file within the NetLogo app so that it points to jri and to my R installation:

<key>NSJavaRoot</key>
    <string>..</string>
<key>LSEnvironment</key>
    <dict>
<key>JRI_HOME</key>
    <string>/Library/Frameworks/R.framework/Resources/library/rJava/jri</string>
<key>R_HOME</key>
    <string>/Library/Frameworks/R.framework/Resources</string>
</dict> 
</dict>
</plist>

在我的代码中添加 extensions [r] 选项卡导致错误：

Adding extensions [r] to my code tab causes the error:

R-Extension中的错误：runOnce中的错误：java.lang.NullPointerException

Error in R-Extension: Error in runOnce: java.lang.NullPointerException

开发人员页面说明了NetLogo 5仍然是测试版，但如果我使用r 2.15及其早期版本的NetLogo和扩展程序进行尝试，我会遇到同样的问题。我估计我所遵循的指示是针对Mountain Lion的，但我想知道这是不是问题。谁设法让Yosemite的扩展工作？

The developer page says that the version for NetLogo 5 is still a beta, but I get the same problem if I try it with r 2.15 and earlier versions of both NetLogo and the extension. I reckon that the instructions that I'm following are for Mountain Lion, but I wonder if that is the problem. Anyone out there who has managed to get the extension working on Yosemite?

推荐答案

设置R的环境变量：一个R.dll和R.exe应该在C：\Program Files \R\R-3.0.1 \ bin \ x64中找到（取决于步骤1中的路径：下载并安装R），

Set environment variables for R: an R.dll and R.exe should be found in C:\Program Files\R\R-3.0.1\bin\x64 (depends on the path in step 1: Download and install R),

首先将R_HOME变量设置为C：\Program Files \ R \ R-3.0.1。

Set at first the R_HOME variable to C:\Program Files\R\R-3.0.1.

现在，通过％R_HOME％/ bin / x64（或直接通过C：\Program Files \ R \ R-3.0.1 \\\ x64）附加PATH变量。

Now, append the PATH variable by %R_HOME%/bin/x64 (or directly by C:\Program Files\R\R-3.0.1\bin\x64).
