R support

[BirgerK]

Is there a reason why this image has no r-support included?

I would like to use R on my Zeppelin. If you're ok with it, I would spent a PR for it.

If you can make it work, I'll be happy to include it. I just don't know enough about R myself.

[BirgerK]

Then I'll do it. :)

One question more: is there a reason why you use not existing maven-goals? I See that you're giving a list oft stuff to maven.

(I would usw those maven-goals for adding R)

[dylanmei]

In an attempt to keep the image from getting too large, I've been very specific about what gets installed.

Getting the size down can be secondary to a functioning Spark R.

[BirgerK]

Then I would like to installiert the whole Spark- and R-stuff by existing maven goals. Okay?

[dylanmei]

Sure! I'll fuss over size later if we think it's an issue. We're currently at 1.6Gb.

[BirgerK]

Please take a look on the PR.

Then, how can we install the R interpreter by ourselves? Is there any solutions ?
