Breaking changes

• 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• export_nest() / export_list() write missing values as NA and do not quote fields by default (na, quote and ...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:/, //).

Unified argument names

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").

| Function(s) | Old | New |

|---|---|---|

| nest_cv(), split_cv(), export_nest(), export_list() | nest_dt, split_dt | data |

| c2p_nest() | cols2bind | cols |

| r2p_nest() | rows2bind, by | names_from, cols |

| export_nest() | nest_cols, group_cols | cols, by |

| top_perc() | trait | cols |

| w2l_nest(), w2l_split(), c2p_nest(), r2p_nest() | nest_type, split_type | out_type |

| export_nest(), export_list() | export_path | path |

| get_path_info() | paths | path |

| import_csv(), import_xlsx() | rbind | combine |

| import_csv() | rbind_label | file_col |

| import_xlsx() | show_excel_name, show_sheet_name (logical) | file_col, sheet_col (column name, NULL to omit) |

Bug fixes

• Fixed a bug in 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.
