Fully support dd::...() syntax (#795).
Threshold for prudence = "thrifty" is reduced to 1000 cells when the data comes from a remote data source.
Support named arguments for dd::...() functions.
This release improves compatibility with dbplyr and DuckDB. See vignette("duckdb") for details.
Pass functions prefixed with dd$ directly to DuckDB, e.g., dd$ROW() will be translated as DuckDB’s ROW() function (#658).
New as_tbl() to convert to a dbplyr tbl object (#634, #685).
Register Ark methods for Positron’s “Variables” pane (@DavisVaughan, #661, #678). DuckDB tibbles are no longer displayed as data frames in the “Variables” pane due to a limitation in Positron. Use collect() to convert them to data frames if you rely on the viewer functionality.
Translate n_distinct() as macro with support for na.rm = TRUE (@joakimlinde, #572, #655).
Translate coalesce().
compute() does not have a fallback, failures are reported to the client (#637).
Implement slice_head() (#640).
Set functions like union() no longer trigger materialization (#654, #692).
Joins no longer materialize the input data when the package is used with methods_overwrite() or library(duckplyr) (#641).
Correct formatting for controlled fallbacks with Sys.setenv(DUCKPLYR_FALLBACK_INFO = TRUE).
Bump duckdb and pillar dependencies.
Use roxyglobals from CRAN rather than GitHub (@andreranza, #659).
Bring tools and patch up to date (@joakimlinde, #647).
Internal rel_to_df() needs prudence argument (#644).
Fix sync scripts and add reproducible code (#639).
Check loadability of extensions in test (#636).
Document slice_head() as supported.
Add Posit’s ROR ID (#592).
Add vignette("duckdb") (#690).
Add experimental badge.
Verbose conflict_prefer() (#667, #684).
Typos + clarification edits to “large” vignette (@mine-cetinkaya-rundel, #665).
Separate ?compute_parquet and ?compute_csv (#610, #622).
Italicize book title in README (@wibeasley, #607).
Fix typo in filter(.by = ...) error message (@maelle, #611).
Improved support for handling large data from files and S3: ingestion with read_parquet_duckdb() and others, and materialization with as_duckdb_tibble(), compute.duckplyr_df() and compute_file(). See vignette("large") for details.
Control automatic materialization of duckplyr frames with the new prudence argument to as_duckdb_tibble(), duckdb_tibble(), compute.duckplyr_df() and compute_file(). See vignette("prudence") for details.
read_csv_duckdb() and others, deprecating duckplyr_df_from_csv() and df_from_csv() (#210, #396, #459).
read_sql_duckdb() (experimental) to run SQL queries against the default DuckDB connection and return the result as a duckplyr frame (duckdb/duckdb-r#32, #397).
db_exec() to execute configuration queries against the default duckdb connection (#39, #165, #227, #404, #459).
duckdb_tibble() (#382, #457).
as_duckdb_tibble(), replaces as_duckplyr_tibble() and as_duckplyr_df() (#383, #457) and supports dbplyr connections to a duckdb database (#86, #211, #226).
compute_parquet() and compute_csv(), implement compute.duckplyr_df() (#409, #430).
fallback_config() to create a configuration file for the settings that do not affect behavior (#216, #426).
is_duckdb_tibble(), deprecates is_duckplyr_df() (#391, #392).
last_rel() to retrieve the last relation object used in materialization (#209, #375).
Add "prudent_duckplyr_df" class that stops automatic materialization and requires collect() (#381, #390).
Partial support for across() in mutate() and summarise() (#296, #306, #318, @lionel-, @DavisVaughan).
Implement na.rm handling for sum(), min(), max(), any() and all(), with fallback for window functions (#205, #566).
Handle dplyr::desc() (#550).
Avoid forwarding is.na() to is.nan() to support non-numeric data, avoid checking roundtrip for timestamp data (#482).
Correctly handle missing values in if_else().
Limit number of items that can be handled with %in% (#319).
duckdb_tibble() checks if columns can be represented in DuckDB (#537).
Fall back to dplyr when passing multiple with joins (#323).
Depend on dplyr instead of reexporting all generics (#405). Nothing changes for users in scripts. When using duckplyr in a package, you now also need to import dplyr.
Fallback logging is now on by default, can be disabled with configuration (#422).
The default DuckDB connection is now based on a file, the location defaults to a subdirectory of tempdir() and can be controlled with the DUCKPLYR_TEMP_DIR environment variable (#439, #448, #561).
New articles: vignette("large"), vignette("prudence"), vignette("fallback"), vignette("limits"), vignette("developers"), vignette("telemetry") (#207, #504).
New flights_df() used instead of palmerpenguins::penguins (#408).
Move to the tidyverse GitHub organization, new repository URL https://github.com/tidyverse/duckplyr/ (#225).
Avoid base pipe in examples for compatibility with R 4.0.0 (#463, #466).
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).as_duckplyr_tibble() to convert a data frame to a duckplyr tibble (#177).?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).as.integer(), NA and %in% (#83, #154, #148, #155, #159, #160).library(duckplyr) calls methods_overwrite() (#164).grepl().intersect(), setdiff(), symdiff(), union(), and union_all() (#169).NA and those used in an expression (#157).head(-1) forwards to the default implementation (#131, #156).left_join() and other join functions call auto_copy().row_number() returns integer.is.na(NaN) is TRUE.summarise(count = n(), count = n()) creates only one column named count.?df_from_file (@andreranza, #133, #134).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).summarise() (#72, #106).summarise() no longer restores subclass.log10() and log().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.
