Hi, I thought I had a handle on the whole singleton class thing but now I''m not too sure. I have a class definition: class ValidationMaster def validate(params) # complex and time consuming validation # returns true on success, raises Exception # on failure end end Okay, so when I''m running my functional tests within rails, I want to be able to control how

...c has had plenty of discussion in the last couple of days, but.... I've been trying to compare the effects of different fitted methods for systems of equations (OLS, SUR, 2SLS, 3SLS ) and would like to compare the residual plots (easy) and the qqnorm/qqplot of the fits for the different fitted methdos. For example, qqnorm( residuals( lm( q ~ p + f + a ) ) ) par( new = TRUE ) qqnorm( residuals( tsls( q ~ p + d, ~ d + f + a ) ) ) The resulting plot contains the two qqnorm plots, and the x axis stays the same. The y axis ("Sample Quantiles") scales for the different plots. I would to f...
