I can't access the database schema of the reactome.db package:

> library("reactome.db")
> reactome_dbschema()

2: In max(ii) : no non-missing arguments to max; returning -Inf
> reactome_dbschema(show.indices=TRUE)

#I found the following schema, but I can't read it

I think you have actually answered your own question. And actually found a bug. :)

To get the current schema you are probably better off using sqlite (and then the .schema command) directly on the sqlite file.

A while ago the schema was changed, and apparently, I did not update it in the package.
Currently, this package is developed in a two pronged way.
I create the mappings, and Valerie adds the full database dump.

There are too many half-manual steps at the moment, and it was already on my todo list to combine all the steps and to make sure we can automate this as much as possible. I will also add a test to check if the schema definition is current.
