Create Wrapper for SuperLearner in R: testAlg$pred error -

-

मेरा कोड: 

  # मेरे परीक्षण आवरण SL.test & lt; - function (Y .temp, X.temp, newX.temp, परिवार, ...) {fit.test & lt; - glm (Y.temp ~ राज्य, डेटा = X.temp, परिवार = परिवार) बाहर & lt; - भविष्यवाणी (फिट। Lt; - सूची (ऑब्जेक्ट = फिट.test) foo & lt; - सूची (बाहर = बाहर, फिट = फिट) वर्ग (foo $ फिट) & lt; - c ("SL.glm") रिटर्न (एफू)} # मेरी लाइब्रेरी SL.library & lt; - सूची ("SL.test") फिट & lt; - SuperLearner (वाई = डेटा.samp $ y, X = data.samp [, सी (2: 7, 9: 11)], SL.library = SL.library, परिवार = द्विपदीय (), विधि = "विधि। एनएलएस", वर्बोज = सच)

त्रुटि:

त्रुटि [, एस] & lt; - testAlg $ pred: प्रतिस्थापन की लंबाई का एक बहुमान नहीं है

यदि मैं तैयार स्लाइडर के साथ SL.library को भरने के बजाय, कोई समस्या नहीं है। उदाहरण के लिए, निम्नलिखित में कोई त्रुटि नहीं है: 

  SL.library & lt; - सूची ("SL.glm", "SL.mean")
< P> किसी भी विचारों की बहुत सराहना की जाएगी यदि उपयोगी हो, तो मेरी आवरण अनिवार्य रूप से परिशिष्ट बी (पी। 585) से एमजे वैन डेर लायन और एस। रोज़ के लिए अनिवार्य रूप से प्रतिलिपि बनाई गई है <लक्ष्य> लक्षित शिक्षा: अवलोकन और प्रयोगात्मक डेटा के लिए कारण निष्कर्ष ।

फ़िक्स सरल था। 

  foo & lt; - सूची (आउट = आउट, फिट = फिट)

से 

  foo & lt; - सूची (पूर्व = बाहर, फिट = फिट)

चाल किया जाहिर है, सुपरएलनर को अब दो वस्तुओं की सूची वापस करने के लिए एक आवरण की आवश्यकता है: भविष्य और फिट।

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
