[英]R integration with node script using r-script
I have two very simple files to test my integration setup. 我有两个非常简单的文件来测试集成设置。 First the r script inside test.R:
首先是test.R中的r脚本:
print('hello')
Then the index.js calling that file: 然后index.js调用该文件:
var R = require("r-script");
var out = R("./test.R")
.data()
.callSync();
And this is what my console is telling me: 这就是我的控制台告诉我的:
$ node index.js
/home/user/index.js:3
.data()
^
TypeError: Cannot read property 'data' of undefined
Currently, I am running Ubuntu 18.04 and if I run only Rscript test.R it works with no problem. 当前,我正在运行Ubuntu 18.04,如果我仅运行Rscript test.R,则可以正常运行。 Any help?
有什么帮助吗?
I fix my similar issue with https://github.com/joshkatz/r-script/issues/19 我用https://github.com/joshkatz/r-script/issues/19修复了类似的问题
If you still feeling lazy to pull the git, you can directly update the source code ./node_modules/r-script/index.js , then edit the function init as 如果您仍然懒于拉git,可以直接更新源代码./node_modules/r-script/index.js ,然后将函数init编辑为
function init(path) {
var obj = new R(path);
_.bindAll(obj, "data", "call", "callSync");
return obj;
}
I hope you may find this helpful. 希望对您有所帮助。
$ cd node_modules/r-script
$ rm node_modules
$ npm install underscore@1.8.3
in my case, downgrade underscore works 就我而言,降级强调
