JAVA调用R脚本 windwos路径下

       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

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

打开Rstudio后会出现JAVA调用不了脚本的情况，关了就好了，待大家发掘

网上关于windows路径的资料太少，试验了好久
