Just run the script, thats it. It downloads the zip file and unzips it, loads the documents and does the analysis. Returns what was asked. Creates two text documents, merged_data.txt which merges training and test set, properly named with activities and only mean and standard deviation variables.
Step by step:
- libarary dyplr loaded
- data downloaded
- data unzipped
- train and test set merged
- variables renamed
- activities added
- variables filtered: only mean and std measures
- duplicate variables removed
- output created
- summary table calculated, per user and activity
easiest is to run source() with the print.eval=TRUE option
