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.
