Vilno is data transformation software distributed under GNU GPL v2

[irishhacker]

It's at code.google.com/p/vilno , as a tarball that can be downloaded
and installed for Linux. The install from source seems quite glitch-
free with Linux with GCC 3.3.x ( I have not been using the most up to
date versions of Linux, sorry about that. ). It comes with numerous
code examples, both beginner's and advanced ( the advanced examples
came from my testing work).

It's used to reshape and prepare data, for example you might use it to
prepare data for analysis and then bring the modified datasets into R.
(Old-fashioned data preparation issues are sometimes hard to do with
the S programming language.) Or you might use it in an ETL context. Or
some other context.

Have a good day.
