我正在尝试使用 org.renjin 包从 Java 运行以下代码。

library('org.renjin.cran:jsonlite')
data <- stream_in(file("src/main/resources/Events.json"))
print(data$timestamp)

我收到以下错误，

org.renjin.eval.EvalException: Exception calling R_parse : Unsupported pointer store to a memory region allocated for primitives.
This means something went wrong during compilation and we allocated the wrong type of storage.

请帮帮我，在此先感谢。

看起来 Renjin 工具链在将 jsonlite 的 C 代码编译为 Java 类方面并不成功。

作为替代方案，您可以使用rjson存在 Renjin 兼容实现的包： http ://packages.renjin.org/package/org.renjin.cran/rjson
