duckplyr 0.4.1

Features

• df_from_file() and related functions support multiple files (#194, #195), show a clear error message for non-string path arguments (#182), and create a tibble by default (#177).
• New as_duckplyr_tibble() to convert a data frame to a duckplyr tibble (#177).
• Support descending sort for character and other non-numeric data (@toppyy, #92, #175).
• Avoid setting memory limit (#193).
• Check compatibility of join columns (#168, #185).
• Explicitly list supported functions, add contributing guide, add analysis scripts for GitHub activity data (#179).

Documentation

• Add contributing guide (#179).
• Show a startup message at package load if telemetry is not configured (#188, #198).
• ?df_from_file shows how to read multiple files (#181, #186) and how to specify CSV column types (#140, #189), and is shown correctly in reference index (#173, #190).
• Discuss dbplyr in README (#145, #191).
• Add analysis scripts for GitHub activity data (#179).

duckplyr 0.4.0

Features

• Use built-in rfuns extension to implement equality and inequality operators, improve translation for as.integer(), NA and %in% (#83, #154, #148, #155, #159, #160).
• Reexport non-deprecated dplyr functions (#144, #163).
• library(duckplyr) calls methods_overwrite() (#164).
• Only allow constant patterns in grepl().
• Explicitly reject calls with named arguments for now.
• Reduce default memory limit to 1 GB.

Bug fixes

• Stricter type checks in the set operations intersect(), setdiff(), symdiff(), union(), and union_all() (#169).
• Distinguish between constant NA and those used in an expression (#157).
• head(-1) forwards to the default implementation (#131, #156).
• Fix cli syntax for internal error message (#151).
• More careful detection of row names in data frame.
• Always check roundtrip for timestamp columns.
• left_join() and other join functions call auto_copy().
• Only reset expression depth if it has been set before.
• Require fallback if the result contains duplicate column names when ignoring case.
• 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

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).

duckplyr 0.3.1

Bug fixes

• Forbid reuse of new columns created in summarise() (#72, #106).
• summarise() no longer restores subclass.
• Disambiguate computation of log10() and log().
• 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.
• Prefer cli::cli_abort() over stop() or rlang::abort() (#114).
• Translate .data$a and .env$a.
• Strict checks for column class, only supporting integer, numeric, logical, Date, POSIXct, and difftime for now.
• If the environment variable DUCKPLYR_METHODS_OVERWRITE is set to TRUE, loading duckplyr automatically calls methods_overwrite().

Internal

• Better duckdb tests.
• Use standalone purrr for dplyr compatibility.

Testing

• Add tests for correct base of log() and log10().

Documentation

• methods_overwrite() and methods_restore() show a message.
