How much data munging is done by Ruby-ists? If you need some tools for preparing data for analysis, transforming data, and cleaning data up, there are some tools to check out at: http://directory.fsf.org/math/stats including: Vilno DAP PSPP DAP is an open-source version of SAS PSPP is an open-source version of SPSS Vilno uses it's own language for data transformation, similar to SQL SELECT, SAS, and SPSS. For statistics itself, I am rather curious about Apophenia ( apparently a C library for statistics that can be called by any statistics package). Robert

Most of the data extraction is done in Perl, mostly because Ruby didn't exist when I wrote most of the code. If there were a couple other Ruby programmers around, I'd port it to Ruby/Rails/Ruport. Nearly all of the statistics I do is in R, also an open source project. There is an R-Ruby bridge called "RSRuby", so that would be another way to get into this. Nearly everything I do these days is large enough that I use either SQL Server or PostgreSQL to manage the datasets. By the end of the year I expect it will all be in PostgreSQL -- the SQL Server licenses are too expensive.
