Hi, I''m fairly new to Rails and am moving from PHP. I am looking for a way to generate generate image plots on a Webpage.

I currently set on IMQ to get the possibility to shape inbound and outbound traffic - so you will see, that the MasterShaper orientate itself on IMQ usage. You can find more information about this projects on the webpage http://sha...

Dear R Users, I would like to plot three time series on the same graph, two axis on the left and one axis on the right. The time series that I am graphing on the left do not share a similar scale: one has a range of 1:100 and the other a range of 25000:70000.

Hi all, Using R a as a real-time application called by Php for a website, I would like to run one R process only, which would manage user connections.
