desc_stats(): descriptive statistics by group
(presets as in rstatix::get_summary_stats(), plus
cv, skew, kurt,
ci_low / ci_high), an optional total row
(counts add up, statistics use all records), min_n,
per-variable digits, labels, report-ready text
via fmt = "{mean} ± {sd}" and a wide report layout
(shape = "wide"). Computed column by column with
data.table’s grouped functions: about a second for a million records in
20,000 groups.import_xlsx() reads multi-row headers
(header_rows, header_sep), using the merged
cells stored in .xlsx files (header_fill), accepts sheet
names in sheet, and can skip unreadable files / sheets
(on_error = "warn").top_perc() now computes its statistics with the same
engine as desc_stats(): columns are lower case
(n, min, max, mean,
median, sd, se, cv),
the CV is NA unless all selected values are positive, and a
new stats argument chooses the statistics.
split_cv() and nest_cv() no longer
depend on ‘rsample’. Folds are built with base R / ‘data.table’. The
splits column (rsample rsplit objects) is
replaced by train_idx / validate_idx (row
indices); ... is no longer forwarded. New arguments
seed (reproducible folds without disturbing the RNG
stream), materialize (FALSE keeps only
indices) and out_type ("df" returns
train / validate as plain data.frames, e.g.
for ASReml-R).
export_nest() now returns the written file paths
(invisibly) instead of a count, consistent with
export_list() and export_xlsx().
export_nest() stops when the grouping columns do not
identify rows uniquely (files would overwrite each other) or name
unknown columns.
export_nest() / export_list() write
missing values as NA and do not quote fields by default
(na, quote and ... are passed to
fwrite()).
r2p_nest() gains id; it stops instead
of silently returning counts when id +
names_from do not identify rows uniquely.
get_path_info(rm_path = FALSE) keeps the root
(/, C:/, //).
The old argument names have been removed; code written for 0.1.x must be updated (calls with old names now fail with “unused argument”).

export_xlsx().w2l_nest() / w2l_split() no longer turn
the caller’s data.frame into a data.table by reference.w2l_split(sep = ) works on every data.table
version.split_cv() / export_list() reject a single
data.frame.import_xlsx(): tables returned by parallel workers get
a valid self-reference; duplicated base names are warned about and made
unique.import_csv(): dots in directory names are no longer
taken for an extension.export_list() / export_nest() sanitise
path components.export_xlsx() rejects
.xls/.xlsm paths and sheets above Excel’s row
limit.top_perc() keeps groups too small to select any record
(N = 0, with a warning); format_digits()
validates digits before using it.convert_nest().get_filename() and
