RConnection c = new RConnection();
// REXP x = c.eval("source('D:\\\\jiaoben\\\\RJava_test.R',encoding = \"UTF-8\")");
REXP x = c.eval("source('D:\\\\jiaoben\\\\Rjava_testx6.R',encoding = \"UTF-8\")");
// REXP eval = c.eval("running()");
REXP eval = c.eval("iscompleted()");
System.out.println(eval.asString()); 脚本内容

Sys.sleep(5)
message("The Task is Finished Successfully!")
iscompleted <- function(){
return("The Task is Finished Successfully!")
}
