为人人自动移植R库

标签: r s4 renjin

我想在我的人人Java应用程序中包含一些本地R库。一些库完全用R编写,一些库有C ++依赖,一些库有S4类。理想情况下,我不想保留每个库的两个副本。

我想知道是否有任何自动方式来获取本地R库(或其源代码)并生成Renjin兼容版本?

packages.renjin.org中列出的所有CRAN和Bioconductor程序包都编译为Java字节码(包括C,C ++和Fortran源),并通过完全自动化的构建系统从原始源打包到JAR中。

Renjin文档包含instructions为Renjin创建,但对于只有R代码的包,与GNU R包的区别仅在于建议(因此是可选的)目录布局。

要根据GNU R的目录结构约定构建自己的R包,必须只添加一个Maven POM文件,其中包含有关R源文件位置的信息。例如(注意包名称和版本的占位符):

将此POM文件放在您的程序包的根目录中并执行mvn package以创建JAR文件。

如果您需要更多自动化,那么您必须自己使用某种构建系统来完成此操作。如果您的包需要它们,请不要忘记向POM添加依赖项(提示:从packages.renjin.org复制POM片段)。
