diffObj {diffobj}R Documentation

Diff Objects


Compare either the printed or str screen representation of R objects depending on which is estimated to produce the most useful diff. The selection process tries to minimize screen lines while maximizing differences shown subject to display constraints. The decision algorithm is likely to evolve over time, so do not rely on this function making a particular selection under specific circumstances. Instead, use diffPrint or diffStr if you require one or the other output.
