This section addresses data related operations. That includes the creation of data by defining for example the values and the data set form, the reading of existing data into R, as also the writing of data in an external file. Further this part is about the manipulation of data, as for example the subsetting of data fragments and all actions which result in a change of a current data set. The Investigation subsection describes all actions, which help to characterize data by for example looking for patterns, comparing data, etc.. All about creating fits to existing data is described in the Fitting section.
