Respect R veterans, I am just starting with R and I am having a difficulty in plotting a rule based decision tree in R. The problem is, I already have an output from hadoop MapReduce and it is in the form of a simple text file. Now I want to use this output from Hadoop and represent it graphically on R. The output file looks something like this. 1 overcast yes1 rain 3 strong no1 rain 3 weak yes1 sunny 2 high no1 sunny 2 normal yes Is there a way that I can represent this graphically in R in something like, http://web.cs.swarthmore.edu/~meeden/cs63/f05/figure3.1.jpg Any help will be much appreciated.
