CodeBook.md contains information about the data and transformations required to tidy the original data set and to obtain the new, smaller tidy dataset.

The code used to produce both the tidy version of the original dataset and the new tidy dataset mentioned in the section above can be found in run_analysis.R and to replicate the process all that is needed is to execute, in an R shell:

source("run_analisys.R")

The code will dowload the dataset for you if it hasn't been downloaded already.

The tidy data set can be found stored in variable tidy and new grouped averages tidy dataset will be stored in variable tidy_subset and also writted to disk under the name tidy_subset.txt.
