R中的SVM分类图(SVM Classification Plot in R)

 我认为你得到[]是因为你在启动时发布了数据，当还没有准备好时，让那个订阅被动反应。 
 
Tracker.autorun(function(){
   Meteor.subscribe("states", function(){
      console.log(states, states.find(), states.find().fetch());
   });
});
 
 可选的 
 
 没有理由在isServer/isClient if语句中声明集合 
 
 由于您从良好实践开始（删除insecure/autopublish包） 
 
 让我们来做。 
 
 首先创建文件夹结构。 （检查meteor / structuringyourapp和这个SO ）。 
 
 在appName/lib/collection.js放了这段代码。 
 
states = new Meteor.Collection("states");
//optional you can place this subscribe inside the appName/client/main.js
if(Meteor.isClient){
   Meteor.subscribe("states", function(){
      console.log(states, states.find(), states.find().fetch());
   });
}
 
 并在appName/server/publish.js 
 
Meteor.publish("states", function () {
    return states.find();
  });

I think you are getting [] because you are publishing the data on the startup, when isn't ready, lets make that subscribe reactive.
 
Tracker.autorun(function(){
   Meteor.subscribe("states", function(){
      console.log(states, states.find(), states.find().fetch());
   });
});
 
OPTIONAL
 
There is no reason to declare the collections inside the isServer/isClient if statements
 
Since you are starting with the Good practices (removing insecure/autopublish packages)
 
Lets do the follow.
 
First Create the folder structure. (check meteor/structuringyourapp and this SO).
 
Inside the appName/lib/collection.js put this code.
 
states = new Meteor.Collection("states");
//optional you can place this subscribe inside the appName/client/main.js
if(Meteor.isClient){
   Meteor.subscribe("states", function(){
      console.log(states, states.find(), states.find().fetch());
   });
}
 
and on the appName/server/publish.js
 
Meteor.publish("states", function () {
    return states.find();
  });
