Pluralization of non-noun names
People, I have an insurance company client and for the last eleven years I have wanted to completely redevelop their system from scratch. However, the boss has never been interested in hiring a team to develop the new system (partly because of the cost and partly because of some famous and expensive development failures in the industry) and has always insisted on incremental development of the

categories/recipes & books/descriptions - has_many vs has_one => id question
People, In the cookbook eg, categories has_many recipes but in a book eg, book has_one description - doesn''t that mean that the id of the description should be the same as the id of the book (instead of having it''s own "description_id" in the book table?

Is there a problem with this? Doesn''t it just mean that there will be a student table

I had a look in Peter's book and the help stuff but couldn't see anything. Thanks, Phil. -- Philip Rhoades Pricom Pty Limited (ACN 003 252

If I use scatter.smooth() I get a nice curve representing

Multiple (7) Y axes?
People, I want to create seven plots on the one graph - each with it's own Y axis and scale - I want the plots overlaid because it is the shape of the graphs that I want to compare, not so much the values. I have found examples where people show how to put two Y axes on the left of the plot but I couldn't find examples of any more than that - is it possible? Thanks, Phil. --

A trivial plot gives open circles as the plot char but another one gives me "q"s . . why is this?
People, On my home computer with a real plot I get what I expect - open circles as the plot character - on my work computer I get "q"s ! So I tried a trivial test plot on the work computer ie: a <- c(1,2,3,4,5) b <- c(1,2,3,4,5) plot(a,b) and that also gives me open circles as it should! - the plot line in my real script is: plot( means5[ ,4 ], means6[ ,4 ],
