#Project from Coursera
You should create one R script called run_analysis.R that does the following.
1. Merges the training and the test sets to create one data set.
2. Extracts only the measurements on the mean and standard deviation for each measurement.
3. Uses descriptive activity names to name the activities in the data set
4. Appropriately labels the data set with descriptive variable names.
5. 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.
Good luck!
To run, it is just necessary that you unzip the zip file in your working directory. It also uses a library named reshape2, the code installs it by it self.
