Fixes #24. When
RSpectra::eigsfails to converge inPredictAttractors(it warns "only 0 eigenvalue(s) converged") the returned$vectorshas no columns, soeig_res$vectors[, 1]dies with the opaque "subscript out of bounds" reported in the issue. This adds a guard right after theeigscall that stops with a message pointing at the degenerate transition graph instead, and a regression test covering the zero-column case.
