Viewing Data: The rdataviewer Package
Paul R. Murrell · 2011
The rdataviewer package is a prototype software tool for the R environment that implements several new ideas for viewing data sets. The “shape ” of the entire data set is always visible to the user, to assist with learning about data structures. In addition, the view of the data set may be interactively zoomed and, for external text files, only the visible part of the data set is loaded into memory. Together these allow very large data sets to be viewed and navigated.
