New table_id argument in compare()
allows custom table identifiers. By default, outputs identify tables as
“a” and “b”. You can now provide meaningful names
e.g. compare(..., table_id = c("original", "updated")),
which are reflected in the output of compare() and related
functions. @elipousson
In the output of compare() with no
table_id specified, the table summary
compare()$tables uses “a” and “b” as identifiers for the
table column rather than “table_a” and “table_b” as used in
prior versions. This is for consistency with the case when custom ids
are provided using the new table_id argument, so that
compare()$tables$table always matches the
table_id argument.
weave_diffs_wide() gains a suffix
argument so column names in the wide output can use custom suffixes
instead of _{table_id}. The default keeps the behaviour of
prior versions. @elipousson
The compare() function now saves a shallow copy of
the input tables. This means functions using a comparison,
e.g. slice_diffs(), now only need the
comparison argument, rather than requiring the original
input tables to be re-supplied.
New functions weave_diffs_wide() an
weave_diffs_long() are added, which show the differing
values in context with other columns from the input tables.
A new function slice_unmatched() is added, used to
get the rows from input tables a comparison shows as not existing in the
other table
A new function slice_diffs_both() is added, used to
get the differences from both input tables in a single output with the
rows interleaved
The error message for duplicated by values now shows
the row which is duplicated
Comparisons are now faster
