Hi there Yes, I know very little of ruby. I must take a crash course? Probabily. Anyway, I try to ask this here. I have a control: customer_controller. From here, I can do something like: @id = 1 @customer = Customer.find(id) Now @customer will contain all the fetched record for customer with id = 1. Great.

Against the often read guideline for rails users to keep with a single db as "more dbs don''t really make sense anyway", my opinion is that it DOES make sense to use more than one db schema for a number of reasons that I won''t

Dear R users, I am having a problem with the main title of a plot. I have written a function returning a plot and I would like that the main title of this plot shows actually the name of the dataset I have used. So, for instance: if my dataset is called Chl, I would like that my plot to be entitled : "Raw periodogram of Chl". I know the function "paste". I suppose I would be
