[R] Best way to study internals of R ( mix of C, C++, Fortran, and R itself)?

How difficult is it to get a good feel for the internals of R, if you want to learn the general code base, but also the CPU intensive stuff ( much of it in C or Fortran?) and the ways in which the general code and the CPU intensive stuff is connected together? R has a very large audience, but my

How do you do a double loop through a matrix or data frame , and within each iteration , do a calculation and append it to a new, second data frame? (So, if your original matrix or data frame is 4 x 5 , then 20 calculations are done, and the new data frame, which had 0 rows to start with, now has

Hello, I have a question as to how the syntax for glht(package multcomp) and estimable (gmodels) works, since I'm not getting everything from the documents I've googled so far, especially with models with 2nd order terms. A modestly complex model: 2-way anova with one continuous covariate, no

[R] Installing R on Ubuntu ( 8.10 ) ?

[R] easy way to find all extractor functions and the datatypes of what they return

Am I asking for too much: for any object that a stat proc returns ( y - lm( y~x) , etc ) ) , is there a super convenient function like give_all_extractors( y ) that lists all extractor functions , the datatype returned , and a text descriptor field (pairwisepval lsmean etc) That would just be so

this blog entry http://www.viggie.com/blog/software/opensuse-ubuntu-usage-experience , if credible , would seem to suggest that there is no good reason to choose Suse. I really don't have time for such nonsense, maybe I'll just reinstall as Ubuntu. Also, noticed that GCC was not installed when

It does look like Gentleman and Ihaka not only lied to the New York Times, but also to the New Zealand Herald and who knows who else. This is disgusting. The R programming language is the S programming language, and Gentleman and Ihaka are not the ones who designed it.

[R] Estimating the standard error when you have sampling weights.

Hi, Where can I find information ( freely available on the Internet , and also books or other sources ) on how having sampling weights changes the calculation of the standard error (of means and proportions)? How good is R for this type of procedure? And SAS? thanks Robert
