collect files as requested by project to create tidy datasets
course : datascientist : module = getting and cleaning data project that was requested : 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 variable names.
- Creates a second, independent tidy data set with the average of each variable for each activity and each subject.
- create a cookbook that describes all operations that have been effected
- upload your scripts in this repo
There is only 1 script call run_analysis.R that reads in all data merges/transforms data/columns selects subset of columns : mean and std writes ou the tidy dataset creates a second dataset with mean by activity and subject
