### Write Sheets

These functions are ready for use but are still under development. You can expect refinements to their interface and capabilities:

• sheets_create() is a new function to create a new Sheet and, optionally, write one or more data frames into it (#61).
• sheets_write() (also available as write_sheet()) is a new function to write a data frame into a new or existing (work)sheet, inside a new or existing (spread)Sheet.
• sheets_append() adds rows to the data in an existing sheet.

More Sheet-editing functionality is coming!

### Other new functions and arguments

There is a new family of sheets_sheet_*() functions that operate on the (work)sheets inside an existing (spread)Sheet:

• sheets_sheet_data() returns a tibble of metadata with one row per sheet.
• sheets_sheet_names() returns sheet names.
• sheets_sheet_add() adds one or more sheets.
• sheets_sheet_delete() deletes one or more sheets.

sheets_cells() gains two new arguments that make it possible to get more data on more cells. By default, we get only the fields needed to parse cells that contain values. But sheets_cells(cell_data = "full", discard_empty = FALSE) is now available if you want full cell data, including formatting, even for cells that have no value (#4).

### Renamed functions and classes

• sheets_sheets() is now sheets_sheet_names(), in order to fit into a coherent family of sheets_sheet_*() functions that deal with (work)sheets. sheets_sheets() still exists but will be removed rather quickly since googlesheets4 is so new.

• The S3 class sheets_Spreadsheet is renamed to googlesheets4_spreadsheet, a consequence of rationalizing all internal and external classes. googlesheets4_spreadsheet is the class that holds metadata for a Sheet and it is connected to the API’s Spreadsheet schema. The return value of sheets_get() has this class.

### Bug fixes

• read_sheet() passes its na argument down to the helpers that parse cells, so that na actually has the documented effect (#73).

• Added a NEWS.md file to track changes to the package.
