Hi all,
I have been working on low-level R library for the Eutils API (equvialent to the Entrez libraries in the Bio* projects). At the moment I'm working on parsing esummary records, with the goal of converting all the data types in these records into their equivalent R object.
I've got that going for the most commonly encountered data types (Integers, Strings, Lists and Structures) but haven't found any records that make use of elements with Type "Flags", "Qualifier" or "Enumerator" , all of which are listed in the esummary dtd (available here).
As I'd like to be as complete as possible, I'd be keen to know if anyone knows of Entrez databases that will contain these data types. Also, if you use such databases I'd be keen to know how you'd expect these data to be represented in R.
