Hello, Today, Brian Ripley commited the revision 50000 of R's svn repository. I took this as an opportunity to do some data analysis of the log and posted some code and graphics on my blog: http://romainfrancois.blog.free.fr/index.php?post/2009/10/09/celebrating-R-commit-50000 The plots of the number of commits per day (and per month) indicates a peak in 2002.

I am not able to #include "R_ext/Altrep.h" from a C++ file. I think it needs two changes: 1. add the same __cplusplus check as most of the other header files: #ifdef __cplusplus extern "C" { #endif ... #ifdef __cplusplus } #endif 2. change the line R_new_altrep(R_altrep_class_t class, SEXP data1, SEXP data2); to

Hi I have a string "56 Fe [1]" that I would like to use as a variable name by using "assign" however I think the spaces and brackets might be causing R some trouble. How can I change the string so that it just becomes 56Fe1 and can be used as a variable name. Thank You Kurt _________________________________________________________________ [[elided Hotmail spam]]

Hello, I want to import R-output via Rserve to Java, especially for the function ctree from the package party. Rserve is working properly. Yet, I only get the predictions with the Java code try{ RConnection c = new RConnection(); ... c.voidEval("modell <- ctree(...)"); REXP y = c.eval("nodes(modell,1)[[1]]$prediction"); ...

Folks, I put up a brief note describing my naive attempts to compute Goldbach partitions, starting with a brute-force approach and refining progressively. http://jostamon.blogspot.com/2009/02/goldbachs-comet.html I'd welcome your suggestions on improvements, alternatives, other optimisations, esp. to do with space vs time tradeoffs. Is this an example interesting enough for

REXP has an asBytes() method. Will this capture the output of an R plot function if a proper graphics device is used? It appears R insists on sending plot output to a file. Kind of strange since it insists on loading all your data into memory before it can do anything. If so then does anyone know what this would be? I prefer png or jpeg. Example: c is an RConnection REXP r =
