You should create one R script called run_analysis.R that does the following.
- Merges the training and the test sets to create one data set.
- Extracts only the measurements on the mean and standard deviation for each measurement.
- Uses descriptive activity names to name the activities in the data set
- Appropriately labels the data set with descriptive activity names.
- Creates a second, independent tidy data set with the average of each variable for each activity and each subject.
- Download and place the data on your harddrive. (See codebook for url source)
- Put run_analysis.R in the parent folder of the data set
- Then set it as your working directory using setwd() function in R.
- Run "run_analysis.R" and it will generate a new file "tiny_data.txt" in your working directory.
For a detailed description of how the function works, see Codebook.md
