Here are the data for the project.

A full description is available at the site where the data was obtained.

The goal of the run_analysis.R script is to accomplish 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.

• set the working directory to 'UCI HAR Dataset'
• read and merge the train data
• read and merge the test data
• merge the training and the test sets to create one data set.
• extract only the measurements on the mean and standard deviation for each measurement
• use descriptive activity names to name the activities in the data set
• label the data set with descriptive variable names
• write the data to a tidy data set as txt file
