GettingAndCleaningData Repository for Cousera: https://class.coursera.org/getdata-008

run_analysis.R should do 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.

Please upload the tidy data set created in step 5 of the instructions.

Please upload your data set as a txt file created with write.table() using row.name=FALSE (do not cut and paste a dataset directly into the text box, as this may cause errors saving your submission). Repository structure -directory /project_data, contains all files needed for evaluation by run_analysis.R

-README.md, this file.

-codebook.md, contains the description of variables produced by run_analysis.R

-run_analysis.R, is the R script that produces the tidyData.txt file

-tidyData.txt, is the file generated by run_analysis.R, which contains the reshaped data set processed from /project_data Running the run_analysis.R script
