// REXP eval = c.eval("running()");
REXP eval = c.eval("iscompleted()");
System.out.println(eval.asString()); 脚本内容

library(Rserve)
Rserve()

Sys.sleep(5)
message("The Task is Finished Successfully!")

iscompleted <- function(){
return("The Task is Finished Successfully!")
}

    如果R连接拒绝,要在R中开启Rserve
