[R] Where to Find Data Transformation Software

[Robert Wilkins]

Hello All,

Here is the requested information. Most of it was on the original post for the
"Tools For Preparing Data For Analysis" thread from last week, but it
got overlooked.
They are all given under an open source license.
Check 'em out!

*******************************************************

Vilno: data transformation software, that reads in input datasets
(rows and columns), crunches through the data, and writes out output
datasets. It's an open source application that can replace the SAS
datastep ( and also replaces proc transpose and proc means ).

Find it at: http://code.google.com/p/vilno
( look in the download section for a tarball, it's a Linux
application, can be opened up (and maybe installed) on an Apple as
well ).

************************************************

DAP and PSPP: open source implementations for SAS and SPSS.

Find it at: http://directory.fsf.org/math/stats

*************************************************

Awk: data transformation/filtering software for semi-structured ASCII files.
A predecessor to Perl.

Find it at: a lot of places, but try:
http://www.gnu.org/software/gawk/gawk.html

Some, but not all , data crunching problems can be handled fairly well by an
all-purpose programming language, such as Perl or Python or Ruby.
Some, but not all, data crunching problems can be handled reasonably
well with the
S programming language ( i.e., R ).
