R export: Added variable labels, extra metadata, fixed partial date

[mennodekker]

Added the variable labels to the dataframe
For meta data I added simple descriptions, variables get their own label and the f.variables for codelists get the codelist name.

Extra metadata
ProtocolID / Site ID
Date of birth or Year of birth
Person ID
Secondary ID
Status for Subject, Event & CRF
Event start/end date + location
Interviewer name and date for CRF

Fixed the partial date
It was output as a number, shopwing essentially just the year

I will commit some improvements later, so please don't merge yet.

Thanks for these. I have a couple of minor requests - could you please:

• split reformatting to a separate commit - it's hard to see what is actually changed in 8a9868f.
• add an example before / after e.g. as is done for the sas_singular XSL, to show what's fixed or changed in terms of output. Although I think the sas_singular example file doesn't have any PDATE items.

[mennodekker]

Thanks for the feedback. Should I move to a new folder like the sas_singular so I can separate the example and include a readme? Suggestion: r_with_factors

[lindsay-stevens]

Sounds good, thanks 👍

Hi Menno and Lindsay,
Great work!
I'm looking into the possibility of using the r-xslt in LibreClinica and I see that Menno's pull-request hasn't been merged. Any particular reason that I should know of?

Hi @GerbenRienk, I haven't merged this mainly because there was no comment to say it was finished or at least ready for another look. Given the long pause, this branch may well be ready to use. I will probably not have time to check that it works for a while.
