...nError in ''Comparer should be sortable on a specific symbol'' #<Mock:0x251b7c8>.[](:mph) - expected calls: 0, actual calls: 1 I assume sort_by is trying to call a [] method ?

Hi all, with PowerPoint and ThinkCell one can draw something they call waterfall chart and it looks like this: http://www.think-cell.com/products/images/waterfall.gif I found discussions on waterfall charts in the archive of this mailinglist, but unfortunately they looked totally different.

Hi, Is there an easy way of converting a gem to a plugin, or at least something you can dump into $RAILS_ROOT/vendor? I''m uncomfortable having stuff like capistrano, the shipping gem, builder, autotest being installed globally as a gem instead of being installed for each application. What do you think? Joe

Dear R-list members, I have a problem with translating a mathematica script into R. The whole script is at the end of the email (with initial values for easy reproduction) and can be pasted directly into R. The problematic part (which is included below of course) is <--- Original Mathematica ---> (* p_svbar *) UiA = Ni (Dsi - 2Di A + A^2)/2; UiiA = Nii (Dsii - 2Dii A + A^2)/2; psvbar =

Does anyone know of any RSpec screencasts for dummies, like me :) I have a Java background, but I have never written a java test in my life. I''ve never learned about TDD or BDD so I''m totally blank on everything that has anything to do with testing and stuff.

I have been learning Rails and building small things over the last several months. Question I have that has been surprising difficult to figure out is this (I know it seems somewhat nonsensical but ignore that).
