Readr Files

This release advances many deprecations.

• melt_csv(), melt_csv2(), melt_delim(), melt_tsv(), melt_fwf(), melt_table(), melt_table2(), and all melt_*_chunked() variants have been removed from readr. These functions were deprecated in readr 2.0.0 (2021-07-20). See the meltr package (https://github.com/r-lib/meltr).

• read_table2() has been removed from readr. This function was deprecated in readr 2.0.0 (2021-07-20) in favor of read_table(). Use read_table() instead.

• read_csv(), read_csv2(), read_tsv(), read_delim(), and read_fwf() now emit a deprecation warning when literal data is passed without wrapping it in I(). For example, usage like read_csv(I("x,y\n1,2")) is preferred over read_csv("x,y\n1,2") (#1611).

• The quote_escape parameter has been removed from write_delim(), write_csv(), write_csv2(), write_excel_csv(), write_excel_csv2(), write_tsv(), format_delim(), format_csv(), format_csv2(), and format_tsv(). This parameter was deprecated in readr 2.0.0 (2021-07-20) in favor of the escape parameter. Use escape instead.

• The path parameter has been removed from write_delim(), write_csv(), write_csv2(), write_excel_csv(), write_excel_csv2(), write_tsv(), write_lines(), write_file(), and write_rds(). This parameter was deprecated in readr 1.4.0 (2020-01-31) in favor of the file parameter. Use file instead.

• The skip_empty_rows argument of fwf_empty() now throws an error if used in edition 2. This argument was deprecated in readr 2.0.0 (2021-07-20).

• The quoted_na argument now throws an error if used in edition 2 with read_delim(), read_csv(), read_csv2(), or read_tsv(). This usage was first deprecated in readr 2.0.0 (2021-07-20).
