PAA and SAX R implementations

Just want to post the figure I've got in R while designing test cases for the Java implementation of the PAA and SAX algorithms. The figure shows original trajectories, their normalized versions, PAA reduction from 14 to 10 points and finally the result of SAX transform into string.


Updated! Linky to the R code

Updated test results:


And the Java-based library I am working on

The lower bounding distance example:
