I show a simple function to do this in my introductory notes available from: http://www.myatt.demon.co.uk basically it is: lreg.or <- function(model) { lreg.coeffs <- coef(summary(salex.lreg)) lci <- exp(lreg.coeffs[ ,1] - 1.96 * lreg.coeffs[ ,2]) or <- exp(lreg.coeffs[ ,1]) uci <- exp(lreg.coeffs[ ,1] + 1.96 * lreg.coeffs[ ,2]) lreg.or <- cbind(lci, or, uci) lreg.or } [[alternative HTML versio...

It seems like it takes me hours to figure out something that I could have written in pure code in minutes. The select_month and select_day helper has been my latest waste of time.

I have a date where the year range is more then I want to define in a select_date scaffold generated year range. My idea was to have the year entered as a text field and the month and day using something like: <%= select_month @person.born,:prefix => :person ,:field_name => "born(2i)" %> <%= select_day @person.born,:prefix => :person , :field_name =>

I am have some problems with UJS. I have a (potentially) large form that I was doing client side validation on (yes there is also some server side validation) using an old prototype validation routine that is not working with the current version. I actually got validation to work by coping and modifying some of the rail.js routine to observer submit. I also had some javascript toggles that I got
