eatATA 1.0.0

• updated overview vignette
• added mathematical formulations of implementation on the help page of itemValuesConstraint()
• added acrossFormsConstraint() for constraints across test forms
• more rigorous input checks for all constraint functions

eatATA 0.11.2

• fix occasional system dependent test failure

eatATA 0.11.1

• fix non ascii character in help file

eatATA 0.11.0

• constraint functions re-named consistently (now ending all on Constraint)
• objective function functions re-named consistently (now ending all on Objective)
• itemUsageConstraint() argument whichItem now takes a character vector (item identifiers) as input
• itemInclusionConstraint() added to force items to be in the same test forms
• stemInclusionTuples() added to create inclusion tuples from column with shared stimulus
• itemExclusionTuples() renamed to itemTuples(), as it can also be used for itemInclusionConstraint()
• argument names in itemTuples() and itemExclusionConstraint() slightly modified
• added simulated item pools for examples
• renamed all item pools consistently (items_mini, items_diao, items_pilot, items_vera, items_lsa)

eatATA 0.10.0

• argument nItems either completely removed from constraint functions or exchangeable with itemIDs
• itemTargetConstraint() substituted by minimaxConstraint(), maximinConstraint(), maxConstraint(), minConstraint(), cappedMaximinConstraint() which allow for different types of optimization goals
• Symphony added as available solver (via Rsymphony)
• inspectSolution() now allows character variables in the input if sums are calculated
• autoItemValuesMinMax() now works for different test length via testLength argument

Documentation

• reworked use case vignette
• added minimal example vignette
• added vignette with package overview

Internal Changes

• input checks (feasible solution?) for analyzeBlockExclusion() and analyzeComplexBlockExclusion()
• uniqueness of argument itemID is checked
• introduction of constraint-class with specific methods and constructor functions

eatATA 0.9.1

• GLPK and lpSolve solvers are now supported
• useSolver() function implemented, which calls solver APIs directly
• inspectSolution() and appendSolution() functions, which use useSovler() output
• prepareConstraints() and processGurobiOutput() retired
• calculateIIF() calculates item information function
• calculateExpectedRT() calculates expected response times

eatATA 0.7.0

• Initial CRAN release.
