Question

我正在尝试使用org.renjin Package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)

我遇到以下错误，

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.

请帮助我，谢谢。

Renjin工具链似乎未能成功将jsonlite的C代码编译为Java类。

作为替代方案，您可以使用rjson包，该包具有与Renjin兼容的实现： http://packages.renjin.org/package/org.renjin.cran/rjson

org.renjin.eval.EvalException：调用R_parse的异常：不支持的指针存储到为基元分配的内存区域
