我正在Linux系统群集（大型计算机）上运行Netlogo，并且我正在使用旧版本的Netlogo-5.2.0，以及R版本3.5及其RPackages（RNetLogo-1.0-1和rJava，它们与Netlogo兼容） -5.2.0）。当我使用命令
NLStart(nl.path, gui=F, nl.obj=my.netlogo1) #Creates an instance of NetLogo
然后它给我这个错误：
Warning message: In `[<-`(`*tmp*`, nl.obj, value = nlo)
也在我开始加载模型时
NLLoadModel(model.path, nl.obj=my.netlogo1)
它给了我这个错误：

任何人都知道这个问题是什么以及如何解决？ 谢谢
