Hi,

I’d like to call R from a rails application. I already installed rsruby  
and works fine with irb, but how do I call it from rails?

I have created config/evironments/rsruby\_environment.rb like so:

require ‘rsruby’  
module R\_Config

R = RSRuby.instance

end

then added it to config/environments.rb:

…

# Include your application configuration below

# rsruby-Configuration

require ‘environments/rsruby\_environment.rb’  
require ‘rsruby’

inserted in a controller like so:

```
r = R_Config::R
@r_pnorm = r.pnorm(0.1)

```

and finally called in a view

\<%= @r\_pnorm %\>

Is that correct? What is wrong?

Thanks,  
Matteo
