Hi, I''m trying to get act_as_nested_set working, and I''m puzzled. I googled the following http://codefetch.com/cache?url=http://media.pragprog.com/titles/rails/code/r ails-code.tgz <http://codefetch.com/cache?url=http://media.pragprog.com/titles/rails/code/ rails-code.tgz&path=rails-code/ar/acts_as_nested_set.rb&lang=ruby&qy=ruby>

Hi all, We are preparing for a future batch, and we may be shorthanded for teaching. R is our programming language of choice. Data Science Retreat (DSR: http://datascienceretreat.com) sits at Microsoft Ventures offices in Berlin Mitte. We have chief-data-scientist mentors and a pretty exhaustive program on machine learning + data science. You can check it out here:

As has been noted by Dan Langille, over at the "cvs-all" mailing list, there are errors in the new Makefile for the chemtool port that make it impossible to build the port. It also stops the INDEX build in its tracks. The "make index" error message is reproduced below: *** *** Error code 1||||||| Stop in /usr/ports/science.||||||| Stop in /usr/ports.||||||| ||||||| ***

I''m looking at possibly going with Image Science (http:// seattlerb.rubyforge.org/ImageScience.html) for an application in development. I''ve heard that it is a lot less overhead than RMagick and we really don''t have any complex image requirements. Are there any folks out there using Image Science that could chime in with some feedback? Also, I have a couple specific

Dear R users and developers, Would any of you be interested in giving a lecture about R and/or R use cases at the following free software conference that takes place in Amiens, France, next summer? We already had a talk on R last year by Yves Croissant (http://2006.rmll.info/theme_26?lang=en) but are still open to any submission this year. We expect some talks this year (to be confirmed) about

Dear list, could someone point me to the right command to subtract 2 columns in a data.frame. Might be a bit embarrassing question. But I cannot figure out how to do this simple command in R.

Dear list, could someone point me to the normal score transform and it's use in R? I would like to transform my data with normal score transform, do some geostatsitical predictions and would like to transform the estimated values back including the estimation variance. Any suggestions? Ulrich -- __________________________________________________ Ulrich Leopold MSc. Department of
