Question

Figure out that R and Rapid-Miner yield the similar number of records in the combined data set or not.

Answer 1

Hi,

R and Rapid miner are data mining tools.Raid miner requires advanced skills.There are certain aspect of rapid miner which is non convenient,but it allow us to keep conventional method by allowing us to fully integrate with standard methods.This is done by using help of rapid miners truly flexible integration with another popular open source data mining tool ,R.

R is powerful operator within the vast library of existing rapid miner studio operators. Both R and rapid miner contains many datas and attributes.In R the arguments of the script correspond to input ports where example sets are converted to data frames.The values returned by the script are delivered at the output port of the operator where data frames are converted to example set.In case of rapid miner the operator builts a merged example set from two or more compatible example sets by adding all examples into a combined set.All input sets must have same attribute signature.The merged example set is delivered as the output.

It is not necessary that R and rapid miner yield similar number of records in combined data set,because on passing data from rapid miner to R,it is nit necessary to pass all attribute ,we may want to select only some of the attributes to pass through to R or entire data set.Passing entire data set is very easy or if we want to select only selected attributes,it can be done by using "select attribute".

Hope you help this.

Thank you...
