R JRI java集成

Question

我需要这方面的帮助：我安装了 JRI，一切正常。我可以启动 rJava 提供的示例，但是当我尝试自己的代码时，这简直是一场灾难。代码如下：

re.eval(".libPaths('C:/Users/the_one/Documents/R/win-library/3.0');");
re.eval("library(forecast);");
re.eval("data<-scan('C:\\Users\\the_one\\Desktop\\RBRTEd1.csv');");
re.eval("plot(data, col=\"blue\", type=\'l\', main=\"Crude oil price 2009  until 2013\");");
re.eval("datats<-ts.(data,frequency=365;");
re.eval("arima<-auto.arima(datats,h5);");
re.eval("test1<-auto.arima(datats,trace=TRUE);");
REXP trace = re.eval("test1;");
System.out.println(trace);
re.eval("dataforcast<-forecast(arima);");
REXP fs = re.eval("summary(dataforecast);");


double[] forecast = fs.asDoubleArray();

for(int i=0; i<forecast.length; i++)
    System.out.println(forecast[i]);

re.end();

我得到的是以下错误：

A fatal error has been detected by the Java Runtime Environment:
