Freeze Parts of a Map

freeze(freeze_row, plan, .data = cur_map())

redist.freeze(adj, freeze_row, plan = rep(1, length(adj)))



Required, logical vector where TRUE freezes and FALSE lets a precinct stay free or a vector of indices to freeze


A vector of district assignments, which if provided will create separate groups by district. Recommended. In freeze defaults to the existing plan, if one exists.
