Twitter is a favorite source of text data for analysis: it’s popular (there is a huge volume of variety on all topics) and easily accessible using Twitter’s free, open APIs which are easily consumable in JSON and ATOM formats.
Some people have used Twitter for sophisticated analysis such as predicting flu outbreaks and the stock market, but let’s start with something simpler and less ambitious: an introduction to text data mining using Twitter and R.

There is a specialized package for R called twitteR, but it isn’t available for Windows, but it’s easy to substitute the generic XML package and the Twitter search API documentation for our needs. Basic Text Mining with R. RDataMining-book.pdf. Tree-Based Models. Recursive partitioning is a fundamental tool in data mining.
It helps us explore the stucture of a set of data, while developing easy to visualize decision rules for predicting a categorical (classification tree) or continuous (regression tree) outcome. This section briefly describes CART modeling, conditional inference trees, and random forests. CART Modeling via rpart Classification and regression trees (as described by Brieman, Freidman, Olshen, and Stone) can be generated through the rpart package. Detailed information on rpart is available in An Introduction to Recursive Partitioning Using the RPART Routines. 1. To grow a tree, use rpart(formula, data=, method=,control=) where 2. The following functions help us to examine the results. In trees created by rpart( ), move to the LEFT branch when the stated condition is true (see the graphs below).
R Decision Tree. Decision tree is a graph to represent choices and their results in form of a tree.
The nodes in the graph represent an event or choice and the edges of the graph represent the decision rules or conditions. It is mostly used in Machine Learning and Data Mining applications using R. Examples of use of decision tress is − predicting an email as spam or not spam, predicting of a tumor is cancerous or predicting a loan as a good or bad credit risk based on the factors in each of these.
