R-2.6.0 package check problems
Hello One of my packages, untb_1.3-2, passes R CMD check under MacOSX (and apparently the systems used in the package check summary page on CRAN) but fails with the following message on R-2.6.0.tgz compiled last night on my (home) linux box. I hasten to add that I have never seen this error before on home-compiled pre-releases of R-2.6.0. Can anyone help me understand what is going on?

Sample size calculation for differences between two very small proportions (Fisher's exact test or others)?
Hi, I'm try to compute the minimum sample size needed to have at least an 80% of power, with alpha=0.05. The problem is that empirical proportions are really small: 0.00154 in one case and 0.00234. These are the estimated failure proportion of two medical treatments. Thomas and Conlon (1992) suggested Fisher's exact test and proposed a computational method, which according to their table

does somebody use XCode on Mac for RoR instead of TextMate?
does somebody use XCode on Mac for RoR instead of TextMate? I wonder how is it compared to TextMate... TextMate uses the default font of Monaco... the Xcode screenshot on Wikipedia uses Courier... I wonder if Xcode looks as good as TextMate when the font is changed to Monaco as well? Thank you. -- Posted via http://www.ruby-forum.com/.
