使用RCocoa在R中加载objective-c库

我在找到了R包Cocoa，我想用它来调用我定制的objective-c类

我尝试加载一个动态库，其中包含一个简单的自定义类（称为

DOHello

，如下所示），然后调用：

hc <- .MClass("DOHello")
h <- .M(hc, "alloc")
h <- .M(h, "init")
.M(h, "hello")

事故报告：

崩溃报告不完整，我只是复制了我认为有用的部分。

这是

Cocoa

中的一个错误，它试图从一个void方法检索结果，现在已修复。请使用stats rosuda-devel邮件列表或通过电子邮件向作者询问问题和错误报告
