[R] Template Engine for R

[Luca Cerone]

Dear all,
I am looking for a template engine for R.

I have already come across {{mustache}} and its R implementation whisker,
however I am looking for something with a few more features like "if blocks",
"for loop", "block inheritance" and so on (for those of you who
are familiar with Python I am looking for something like Jinja2 or Mako).

I searched in google, but the only option for R seems whisker.

Can any of you recommend me some alternatives?

Thanks a lot in advance for the help!

Cheers,
Luca
