Allows to extend existing enums

[msevestre]

@PavelBal CAn you add a test file for this? The behavior is starting to justify it :)

[msevestre]

woudl it work with keys being ONE value and not an array?

[PavelBal]

Yepp.

[msevestre]

So why do we always do sthg like this in ospsuite-r

quantities<- c(quantities) to ensure that we have a list

[PavelBal]

I think... Because a quantity (or any R6-object) by themselves are kind of a list, and trying to iterate over an R6-object produces some mess... Having an object as enum-key would not work.

[msevestre]

oh yeah that's right. Thanks brother

[PavelBal]

@msevestre I added some tests.

[msevestre]

@PavelBal Build is failing

[msevestre]

oh yeah it's failing because I need to merge the other branch first. then if you can merge/rebase develop into your branch, we should be good to go

[PavelBal]

@msevestre rebased

[msevestre]

looks good. I'll merge when the build is finished

[msevestre]

@PavelBal You need to create thew new documentation file (CTRL+SHIFT+D )to update the documentation. Otheriwse it won't be vibisle

[PavelBal]

Oh, I thought it's re-created on build... Added!

[msevestre]

still one example that is being run...pain in the butt.
https://ci.appveyor.com/project/open-systems-pharmacology-ci/ospsuite-r/builds/38385449

You probably need to regenerate the documentation so that it is being updated.

[PavelBal]

@msevestre Actually, I just realized... I expose all those methods, but we do not expose enum itself (also this is why examples are failing). I think we should either export everything or nothing. I would prefer exporting enum so it can be used by user. What do you think?

[msevestre]

This was an issue because enum is used in TLF and other Lib and we were getting conflicts. That why we didn't export. Yes you can still use it from the outside?

[PavelBal]

Yes you can still use it from the outside?

You cannot create a new one:

> library(ospsuite)
> myEnum <- enum(c("a", "b"))
Error in enum(c("a", "b")) : could not find function "enum"

[msevestre]

What we can try to do is
expor the one in ospsuite.core
Do not create one at all in ReportingEngine and use this one
Rename the one in tlf.
For some reason, I think this was not working

Anyway, in the meantime, can you put the dontrunn flag or sthg like this in the example so that the build passes?
