This dataset has been created to fulfill the requirements of the Getting and Cleaning Data Course from Coursera.
Based on data set provided by course instructors which is, in turn, has been derived from human activity data collected using smartphones.
-
README.md: this file;
-
run_analysis.R: source data transformation script;
-
CodeBook.md: metainformation about data file and details of transformation procedure;
-
ms-aggregate.txt: data file itself (not available from GitHub, uploaded directly to Coursera grading infrastructure).
According to project instructions,
- a code book that describes the variables, the data, and any transformations or work that you performed to clean up the data called CodeBook.md.
details about steps performed to produce the data set should be placed into the CodeBook.md. This contradicts with submission instructions which specify putting them in README, but codebook seems be more appropriate place to keep things together.
