Hi,

I am searching for a ruby class/method to calculate quantile  
statistics.  
Does anyone know or have a solution for me?

Thanks in advance,

Dear neuholger,

have a look at the statistics2 project on RAA.  
Otherwise, you might try rsruby - an interface from Ruby to the R  
statistical  
language.

Best regards,
