...ect proposal at: http://rwiki.sciviews.org/doku.php?id=developers:projects:gsoc2010:syrfr I am looking for a mentor to guide me through the summer on the project under the Google Summer Of Code program (GSOC 2010) with relevant experience in Symbolic Regression or Genetic Programming in general.

...nd define the meaning of arithmetic for them. I had checked for operator overloading in R but could only find the equivalence of a + b and '+'(a, b) in the R language definition. Could you show how I could extend the simple object oriented-ness in the C++ code neatly to R? Thanks a bunch! Chillu [[alternative HTML version deleted]]

Per http://rwiki.sciviews.org/doku.php?id=developers:projects:gsoc2010 -- and http://rwiki.sciviews.org/doku.php?id=developers:projects:gsoc2010:syrfr -- I am applying to mentor the "Symbolic Regression for R" (syrfr) package for the Google Summer of Code 2010. I propose the following test which an applicant would have to pass in order to qualify for the topic: 1. Describe each of the

Hello R wizards, What is the best way to read a data file containing both fixed-width and tab-delimited files? (More detail follows.) _*Details:*_ The U.S. Bureau of Labor Statistics provides local area unemployment statistics at ftp://ftp.bls.gov/pub/time.series/la/, and the data are documented in the file la.txt <ftp://ftp.bls.gov/pub/time.series/la/la.txt>. Each data file has five

Dear All, I've been?searching for?appropriate codes to compute the rate of change and the curvature?of ?nonparametric regression model whish was denoted by a smooth function?but?unfortunately?don't manage to?do?it. I presume that such characteristics from a smooth curve can be determined by the first and second derivative operators. The following are the example of fitting a

Hi I implemented the age-structure model in Gove et al (2002) in R, which is a nonlinear statistical model. However running the model in R was very slow. So Dave Fournier suggested to use the AD Model Builder Software package and helped me implement the model there. ADMB was incredibly fast in running the model: While running the model in R took 5-10 minutes, depending on the
