Published on Feb 14, 2013

This webinar focuses on data mining as the application area and show how anyone with just a basic knowledge of elementary data mining techniques can become immediately productive in R. Contents:

         Provide an orientation to R's data mining resources

         Show how to use the "point and click" open source data mining GUI, rattle, to perform the basic data mining functions of exploring and visualizing data, building classification models on training data sets, and using these models to classify new data.

         Show the simple R commands to accompli

 

 

5. Introduction to Data Mining with R: Regression Trees, Bodyfat Dataset 

Part 1, 10:11"; Part 2,10'40"; Part 3, 14'37"

 

Published on Dec 21, 2012

These are videos from an Introduction to Data Mining using R online course. The topic in this session is Decision Trees for Classification and Prediction. We demonstrate and explain two examples (two datasets which relate to studies on bodyfat, and then glaucoma) in which we "grow" regression trees using two algorithms for each example: (1) recursive partitioning (rpart function) and (2) conditional trees (ctree function). We draw and explain both of these examples using the R scripts and documentation that is freely available in the HSAUR2 package on the Comprehensive R Archive Network (CRAN) for R software.

 

6. Using R with Hadoop video, 1:00:14

Published on Jan 24, 2013

 

R and Hadoop are changing the way organizations manage and utilize big data. Think Big Analytics and Revolution Analytics are helping clients plan, build, test and implement innovative solutions based on the two technologies that allow clients to analyze data in new ways; exposing new insights for the business. Join us as Jeffrey Breen explains the core technology concepts and illustrates how to utilize R and Revolution Analytics' RevoR in Hadoop environments.
