Typo in Lua interface example

[jgoldfar]

The Lua example here https://github.com/shogun-toolbox/shogun/blob/develop/doc/readme/INTERFACES.md appears to have a typo; the call to run the example should probably be closer to what is generated by https://github.com/shogun-toolbox/shogun/blob/develop/examples/meta/lua/CMakeLists.txt (I don't run lua locally, otherwise would submit a PR)

Whoops, indeed!
Thanks for reporting.

This is a lovely entrance task for those try to get involved in Shogun.

The R command also is not rendered properly, so that needs a mini fix as well

I want to take up and work on this issue.

[karlnapf]

do it :)

[prashanthduvvada]

Well, do I need to create a separate issue and create different PR for R command?

[karlnapf]

Nope, just fixing typos can be done in a single PR which consists of 1-2 lines
