I would like to ask, how can I access this value in my rails application to display it? Thanks ! By: Johnny Nguyen RE: Accessing R packages through RSRuby [ reply ]   2009-06-08 13:25 What happens when you do: R=RSRuby.instance R.library("concord") R.kripp_alpha( parameters ) By: Dhairya Dand Accessing R packages through RSRuby [ reply ]   2009-06-08 11:42 How does one access R packages through RSRuby, I wanted to access the kripp.alpha function in the Concord Package, I have installed the package as well as set Concord to load as a default package, I have tested the function through R and it runs just fine. However under RSRuby it says 'variable kripp.alpha not found' I am using - R=RSRuby.instance R.kripp_alpha( parameters ) Could you please point out any mistake or suggest ? Thanks a lot !
