Actually it's the other person who declined to make their code available. Erics 
code is on github. It doesn't appear to me that it has any library licensing

Hi Amos,

I have not understood his statement as a decline to make it available (btw
it is). I rather think he is using software which licenses (GPL) are not
compatible for inclusion within Apache Zeppelin.

Cheers
Guillaume

Ok.  There were replies to this regarding two codebases.  One, the author
has declined to make available.  The other, appears to have been written
last night, and well it’s a start.

Are either of you interesting in collaborating on this or should I just go
and do?

Thanks,

Subject:  Re: R?

I have released a zeppelin-R interpreter which supports cross paragraph
variables and R plot (ggplot2...);

https://github.com/datalayer/zeppelin-R

Due to GPL2 license of used libraries, this can not be released under
ASL2 (http://www.apache.org/foundation/license-faq.html#GPL).

Once ZEPPELIN-154 is implemented, you will be able to use it.

I will check if SparkR works fine, but as the R interpreter supports any
R library, I don't expect issue.

Hi,

Just a question, does it mean it for SparkR or pure R?

I've been working on one, I'm sure it would need more work after the
initial pass and would appreciate your help

Is anyone working on an R interpreter? I'm looking for a project where I
can make a contribution and this seems like one.
