dosearch 1.0.12 (2025-09-26)

• Fixed an issue related to an upcoming igraph update.

dosearch 1.0.11 (2024-07-16)

• Fixed a memory allocation issue with LDAGs.

dosearch 1.0.10 (2024-07-09)

• Added support for user-defined context-specific variables for LDAGs via con_vars in control.
  • Removed C++11 from system requirements (for CRAN).

dosearch 1.0.9

• Added several sanity checks for the input distributions and the graph.
  • Updated the documentation in various aspects. Importantly, it is now noted that dosearch is not complete for missing data problems.
  • A non-identifiable query is now reported as follows: "The query is non-identifiable by do-search" to further clarify that the search was not able to identify the query.
  • Added a new Vignette for the package.
  • Added a plot method via the DiagrammeR package to produce derivation plots more easily.
  • An error is now issued when the input graph is too large.
  • Fixed an example on transportability in the dosearch function documentation.

dosearch 1.0.8 (2021-08-19)

• Added citation for the related article in the Journal of Statistical Software.

dosearch 1.0.7 (2021-08-12)

• Changed the default option of the search heuristic to FALSE for all instances.
  • Implemented minor performance tweaks to the search algorithm.
  • Added more options for benchmarking.
  • Restored a legacy control parameter for internal use.
  • Moved igraph and dagitty packages to 'Suggests'.

dosearch 1.0.6 (2020-10-26)

• Fixed a case where the search would continue unnecessarily for some time after discovering the target distribution.

dosearch 1.0.5

• The resulting list of the 'dosearch' function call now has the class dosearch with print and summary methods.
  • Added accessor functions get_formula, get_benchmark and is_identifiable to query an object of class dosearch.
  • The function get_derivation is now repurposed as an accessor function, and dosearch is now the only function for query identification.
  • The graph argument of dosearch now supports the igraph format used by the causaleffect package (see dosearch documentation for examples).
  • The graph argument of dosearch now supports DAGs created using the dagitty package (see dosearch documentation for examples).
  • Fixed an issue when using benchmark = TRUE in control.

dosearch 1.0.4 (2019-10-22)

• Fixed compilation issues on some platforms.

dosearch 1.0.3 (2019-10-18)

• Now supports context specific independence relations (CSIs) via labeled directed acyclic graphs (LDAGs). See the documentation and examples for more details.
  • The function get_derivation can now also be called via dosearch.
  • Bidirected edges can now also be given as <->.
  • Added a new control parameter, time_limit, which will terminate the search when the given amount of time (in hours) has passed (only when benchmark = TRUE).
  • Some redundant control options have been removed.
  • Fixed an issue with derivation rules when missing data was present.
  • Fixed an another minor issue regarding missing data.
  • Fixed a rare issue with formula generation.

dosearch 1.0.2 (2019-02-28)

• Added an example on how to produce an image from the DOT derivation.
  • Added a warning when the response indicator for a proxy variable is not present in any data source.

dosearch 1.0.1 (2019-02-08)

• Added a Vignette describing the search procedure.
