Inter-aggregate commands/transactions in an eventual consistency manner

I am trying to model a business transaction that operates on two aggregates. Let’s say we have a Bag aggregate type that contains Items (entities). I would like to have a command TransferItemToBag(itemName: String, fromBag: BagId, toBag: BagId) which extracts an item from the first Bag and puts it to the second one. When this command is received, I want to send a command AddItemToBag(…) to the second bag and when it responds with ItemAddedToBag(…) send RemoveItemFromBag(…).

GHap package in R, ghap.anctrain function-aggregate error

The ghap.anctrain function of GHap package for genomewide haplotype analysis in R shows the following error “Error in aggregate.formula(formula = geno ~ pop, data = dfp, FUN = mean):
argument ‘x’ is missing — it has been renamed from ‘formula'”
The error seems to be with the modification in aggregate.formula. Can this be solved?
I am using R 4.3.1. The GHap package version is 3.0.0.
