Fix failure when comparing two S3 objects with incompatible types.
Description of S3 objects now includes base type.
compare()
gains a new max_diffs
argument that allows you to control the maximum number of differences shown. Set max_diffs = Inf
to see all differences (#49)
Logical vectors fall back to element-by-element comparison in more cases (#51).
Long-form diff no longer confuses additions and deletions (#52, @krlmlr).
Handle S4 objects that have attributes that are not slots.
Additions are now coloured blue and deletions yellow (instead of the opposite).
compare()
now labels output as old
and new
, since that’s the most natural way to use it.
compare()
can selectively ignore attributes by providing vector to ignore_attr
(#45).
print()
method gets n
argument to allow explicitly specifying number of differences to show (@mnazarov).
Improvements to comparison display:
Zero length vectors compare robustly (#39)
Line-by-line comparisons show modifications as deletion then addition, rather than addition then deletion (#44).
Differences between numeric vectors are more robust, particularly in the presence of missing values (#43). The number of digits selected has also been slightly improved so that you’re more likely to get exactly the number of digits needed.
All objects: class (#26) and names (#31) are ignored when ignoring attributes.
Numeric and logical vectors: clearer display of differences. Numbers are right-aligned, and we show the numbers not the differences.
Character vectors: a trailing newline is no longer ignored (#37).
Lists: all elements of the unnamed lists are compared, not just the last! (#32)
Lists: unclassed prior to comparison (#21).
Data frames: The internal representation of row names is no longer used; instead we use the same result of rownames()
(#23).
Environments: New ignore_formula_env
and ignore_function_env
arguments to ignore formula and function environments for compatibility with all.equal()
(#24).
Expression objects: can now be compared (#29).
Calls: srcrefs and attributes are ignored.
compare_proxy()
is now exported so that you can provide methods if your objects need special handling (particularly needed for objects that contain external pointers) (#22).
Fixed a partial argument name in as.list()
