How to call RScript function in an extension

Anonymous — Wed, 19 Sep 2018 16:37:20 GMT

Looking for advise on how to call an RScript in an extension backend. I have configured R with Qlik Sense and the script gets called successfully from front end.

Extension Functionality - When user clicks on a button, the extension should dynamically create an QHypercube (internally call R Function) and display its output.

Below is my code

controller: ['$scope', function ( $scope ) {

var app = qlik.currApp();

$scope.checkIfButtonPressed = function($event){

app.createCube({

qDimensions:[],

qMeasures:[{

qDef:{

qDef:"R.ScriptAggr('count(q$survived);',survived)" //-- this doesnt give any output

//qDef: "count(survived)" --this works

}

}],

qInitialDataFetch:[{

qHeight:20,

qWidth:2

}]

},function(reply){

alert(reply.qHyperCube.qDataPages[0].qMatrix[0].qNum);

}

});

}

Thanks,

Hari Krishna

I figured it. Calling R from hypercube works, I was using count() function which has to be len() in R. I could see data being sent to RServe and the communication happening. Thanks
