• row_number() returns integer.
• is.na(NaN) is TRUE.
• summarise(count = n(), count = n()) creates only one column named count.
• Correct wording in instructions for enabling fallback logging (@TimTaylor, #141).

Chore

• Remove styler dependency (#137, #138).
• Avoid error from stats collection.

Documentation

• Mention wildcards to read multiple files in ?df_from_file (@andreranza, #133, #134).

Testing

• Reenable tests that now run successfully (#166).
• Synchronize tests (#153).
• Test that vec_ptype() does not materialize (#149).
• Improve telemetry tests.
• Promote equality checks to expect_identical() to capture differences between doubles and integers.

duckplyr 0.3.2 (2024-03-17)

Bug fixes

• Run autoupload in function so that it will be checked by static analysis (#122).

Features

• New df_to_parquet() to write to Parquet, new convenience functions df_from_csv(), duckdb_df_from_csv(), df_from_parquet() and duckdb_df_from_parquet() (#87, #89, #96, #128).

• Fix division by zero for positive and negative numbers.

Features

• New fallback_sitrep() and related functionality for collecting telemetry data (#102, #107, #110, #111, #115). No data is collected by default, only a message is displayed once per session and then every eight hours. Opt in or opt out by setting environment variables.
• Implement group_by() and other methods to collect fallback information (#94, #104, #105).
• Set memory limit and temporary directory for duckdb.
• Implement suppressWarnings() as the identity function.
