People, I have tables years and teams and I have the years listing like: 1965 1966 1967 . . I want to be able to click on the year and ONLY list teams for that year.

People, I am using: before_filter :login_required in my Controllers and this works fine. For some tables I am happy to use the output of eg: ruby script/generate scaffold Author but is there some way that I can disable Create, Edit, Destroy for some user logins in the corresponding view?

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

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?

People, It appears that one has to use Imperial measurements in plot parameters? I can't find any info on using metric units . . Thanks, Phil. -- Philip Rhoades Pricom Pty Limited (ACN 003 252 275 ABN 91 003 252 275) GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil at pricom.com.au

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. --

People, It appears that there is no way of getting Boxplots to plot using Mean, SD, Max & Min - is there something else that would do what I want? I couldn't find it . . Thanks, Phil. -- Philip Rhoades GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil at pricom.com.au

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 ],

People, A couple of decades before I was retired and was still working for other people I had cause to install UPSs and they usually had RS232 ports to allow the setting up of shutdown scripts to UNIX / Linux servers. Now, after not having to be concerned by those issues for some time - most of my little web sites have been on Digital Ocean or other suppliers VMs for a long time - I am

People, I am using the "las=2" parameter to rotate the labels for the X axis ticks but it means that they are almost touching the "xlab" string. I have been messing around with the "mai" paremeter but that doesn't help - is there some way of increasing the space between xlab and the X axis tick labels?
