zealous-waffle is course project for the course Getting and Cleaning Data : https://www.coursera.org/course/getdata
The only package required is plyr. Make sure you have it with the command:
install.packages("plyr")The script will then automatically load the library.
run_analysis.R downloads the data from the web and 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 variable names.
- From the data set in step 4, creates a second, independent tidy data set with the average of each variable for each activity and each subject.
- Saves the tidy dataset in your current working directory
Curious about the name zealous-waffle? I am a currently like a zealous waffle. Hopefully one day I am gonna be a zealous data scientist.
