Script called "run_analysis.R" is preparing two data frames.

First data frame called full.dataset contains all data merged from test files and train files. Apart from standard 561 variables it contains column origin which describes origin of data (test/train), subject which contains subject number and activity.labels which contains labels for activities.

Second data frame second.dataset contains mean values for all variables for subjects in particular activities. We have 6 activities and 30 subjects which gives 180 combination of subjects in activities. Means are calculated for every 561 variables.

Every task for this project is marked with commentary in source code.
