main.R finds averages on all concerned variables on two datasets and writes them into a text file
refer to comments for proper STEP# reference
STEP 1: all data is merged STEP 2: significant data is extracted (mean and standard deviation) STEP 3+4: names are properly assigned STEP 5: new dataset of all activity and subject averages into a text file
Variables:
[1] "activities" "features" "fileUrl" "full_data" "means_data" "somethingNew" "stats_features"
[8] "subj_test" "subj_train" "subject_data" "x_data" "x_test" "x_train" "y_data"
[15] "y_test" "y_train"
"data" datasets are merged from "train" and "test" datasets "features" applies the name changes to "x_data" while "stats_features" extracts statistic data from STEP 2.
