ompr.roi 0.8.0

Breaking changes

• The package exports column and row duals of LPs. Extracting duals might be solver dependent. Only tested with GLPK. This requires version 0.8 of ompr.
• Minimum supported version is 3.4.0 since slam also requires >= 3.4

New features

• ompr.roi works with other ompr backends as well.
• ompr.roi always returns a solution, even if the solution status is not optimal. It extracts the ROI solution with force=TRUE.

ompr.roi 0.7.0

Major breaking changes

• The package uses the new sparse matrix interface of ompr and ROI.
• Minimum supported R version is now 3.3.0

Minor changes

• as_ROI_model exports an ‘ompr’ model to ROI::OP Github Issue #9

ompr.roi 0.6.1

Bugfix

• Fixed a bug where the ROI::V_bound object was incorrectly initialised. This causes an error with ROI >= 0.3.0.
