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.
diffObj(target, current, ...)a Diff object; see diffPrint.
