Dinamica EGO 4 features many improvements when compared to version 3 including, but not limited to:

• Hundreds of bug fixes! Dinamica version 4 simply works better than version 3 that was a really great version of Dinamica.

• It can installed alongside version 3. This allows you to keep both versions independently on the same computer making the migration processo from version 3 to 4 easier and less stressful.

• The input maps used by a model now can have different resolutions, number of lines/columns, registration coordinates etc. The only constraint is that all maps used by a model must share the same projection.

• The R language can be used to implement parts of a model. Basically, the user can use a custom R script to manipulate data the same way any Dinamica functor would do. See the documentation about Calculate R Expression and about model coupling for some addition information on how to use R in a Dinamica model.
