Description

Have a look at our analytic tests: https://github.com/JuliaDynamics/RecurrenceAnalysis.jl/blob/main/test/rmatrix_analytic.jl#L97-L116

The local recurrence rate results are wrong. They do not give what is expected analytically and due to the symmetries of the input set. Something is wrong. We have to fix this.

Research direction

Start with the analytic cases in test/rmatrix_analytic.jl, lines 97-116, and run those tests to reproduce the incorrect LocalRecurrenceRate results. Compare the observed values with the analytical expectations and input symmetries, then trace the LocalRecurrenceRate entry point to locate the discrepancy. Done means the analytic results match the expected values and the tests pass.
