errorlocate 1.1.1

• Fix for R 4.3.2: is.atomic(NULL) was TRUE, but now it is FALSE.

errorlocate 1.1

• For values > 1e7 in combination with another value NA locate_errors generated an error. Reported and fixed by Ramon Reinders (issue #36)

• support for in_range (issue #33)

errorlocate 1.0.0

• Fixed a nasty bug in which variable names are mangled by lpsolveAPI, depending on the seed / added random noise. Thanks to Patrick Driessens

• Added expand_weights, which helps in specifying detailed weights for records

• Removed a bug: Ncpus was ignored in replace_errors

errorlocate 0.9.9

• Added support for Inf weights, thanks to Guido van den Heuvel.

• Improved default setting of solver epsd = 1e-12 provides better numerical stability.

• Too aggressive presolve default for lpSolveAPI (c(“rows”, “cols”)) (issue #34) , switching back to presolve=“rows”. Thanks to Sander Scholtus.

errorlocate 0.9.8

• Added parallel processing options, resulting in speed and memory consumption improvements. (also for Ncpus=1).

• simple ratio’s are taken into account and rewritten into linear rules: cost/turnover > 0.6 will be rewritten into cost > 0.6 * turnover.

• bug fix issue #31: when a record was invalid, but all rules involving the invalidation contained missing variables, the record was skipped by errorlocate.

• Bug fix for issue #30: when a value >= 1e7 was encountered, all fields were flagged erroneous. Thanks to Garðar Páll Gíslason.

• Bug fix for log1p, log10 function approximation.

• In long running locate_error sessions, the mip solver returned for some records a numerical instability error code. Seems to be an instability in lpSolve. Resubmitting same record does return a solution. When a numerical instability in lpSolve is reported a record is try again. When this fails, it is saved in mps format to the temporary directory (with a warning).

errorlocate 0.5.1

• Better name generation for soft linear equality constraints
• Only values of the data.frame that are used in the constraints are added to the matrix.
• Fix for issue #25, when a variable contains only one category. Thanks to @nickforr.
• Fix/warning for issue #27, using an integer variable for categories. Thanks to Jeffrey Hoogland for reporting.
• Fix for handling NA logical values (issue #29).
• Added status and duration info to errorlocation. Thanks to Sander Scholtus
• Improved progress bar, showing percentage and taking into account records without errors
• added inspect_mip function, allowing for an in depth examination of the mip translation and execution. Making it easier to debug/find what is wrong with a record / rule set
• experimental functionality for log transformed variables, can be switched on with options(errorlocate.allow_log = TRUE). This makes it possible to formulate constraints total_salary >= min_salary * n_employees as log(total_salary) >= log(min_salary) + log(n_employees).

errorlocate 0.4

• Implemented optimization, only invalid records are now treated. Can greatly enhance processing time! Thanks to Jos de Waard.
• Fixed issue #21, thanks to Sander Scholtus: strict equalities
• Fixed issue #22, thanks to Sander Scholtus: missing columns in data.
• Fixed issue #23, “ ==”” FALSE in if clause was handled incorrectly.

errorlocate 0.3.0

• Fixed issue #19 and #20: rules now may contain var_group and assignments
• Fixed an issue with soft constraints: type of variables was sometimes incorrect
• Parsing of if statements with more than 2 expressions in the condition is now improved

errorlocate 0.2.0

• Fixed issue #17: if-rules may contain a linear equality.
