Curry: proposed new functional programming, er, function.
Hi all (especially R-core) I suppose, With the introduction of the new functional programming functions into base I thought I'd ask for a Curry() function. I use a simple one that looks this: Curry = function(FUN,...) { .orig = list(...);function(...) do.call(FUN,c(.orig,list(...))) } This comes in really handy when using say, heatmap():

S4 methods semantics questions
Some quick questions about S4 methods. Does the typing of S4 methods mean that lazy evaluation is no longer possible? It seems that you would need to evaluate the arguments to determine their type at dispatch. Second, what role, if any, do default arguments play in S4 methods? I notice that you can put default arguments into generics but that the dispatch is still done on the type of the

methods and try()
Hi all, I'm having a problem with some sort of interaction with try() and methods, I think. The setup is as follows, I have an S4 class that holds an environment and I would like to evaluate the right hand side of a function inside that environment. No problem there. However, if the formula involves a symbol that doesn't exist, which may or may not happen, it fails as it should and

Anon CVS updates?
Is the anonymous CVS repository for R presently broken? There haven't been many updates coming through and the repository files seem to differ significantly from the rsync version of R-devel...

Problem building methods package?
For the last, I dunno, week or so I've been unable to build R... I finally took the time to investigate and the crash is in building 'methods': all.R is unchanged ../../../library/methods/man/methods.Rd is unchanged make[2]: `Makedeps' is up to date. ../../../../library/methods/libs/methods.so is unchanged make[1]: Nothing to be done for `Rfiles'.

PCRE in development code?
So PCRE dropped into R-devel recently, I tried just dropping 3.9 (latest version) into src/extra/pcre and compiling on Win32 but its dying during the final link (undefined reference to 'pcre_free') is there some special magic I'm missing or do I get to hunt this one down on my own?

R-devel Mac OSX build wierdness...
I encountered some wierdness when building R-devel (latest rsync) on OSX using commandline tools (as opposed to the Carbon GUI and whatnot...probably just laziness on my part but it generally works :-)). At any rate, sometime between 2002-07-05 and the present the configure scripts started setting INSTALL_DATA to ${R_HOME}/bin/install -c in Makeconf...which causes wierdness for the Mac OSX

R graphics device for flash apps
Byron, I just read your blog (statcomp.blogspot.com, linked from your other post) and rand across your idea of an R/Flash graphics device. I've also been giving this some thought because of this amazing interactive flash app: http://tools.google.com/gapminder and others from http://www.gapminder.org/. I would love more than anything to work on this. The only hitch is that I'm so

'R CMD build' fails when there are spaces in the path (PR#6830)
Full_Name: Byron Ellis Version: R 1.9.0 (and 2.0.0) OS: Linux (Redhat Fedora Core) Submission from: (NULL) (140.247.241.197) It appears that `R CMD build` cannot handle spaces in the path when building packages for distribution.

external pointers
I have some C data I want to pass back to R opaquely, and then back to C. I understand external pointers are the way to do so. I'm trying to find how they interact with garbage collection and object lifetime, and what I need to do so that the memory lives until the calling R process ends. Could anyone give me some pointers? I haven't found much documentation. An earlier message

Graphics driver test script?
Hi, 1. I started work on a metapost graphics driver a week or so ago and it is gradually taking shape. I'm building up my own test cases into a script as I go, but figured you may have a "canonical testing script" of cases a driver must handle? 2. The clipping function looks like being a tricky problem. It seems to me that the callers of the driver assume that clipping affects all

Hook for running a function before evaluation
Hello, I like much addTaskCallback() and friends. However, there are situations were we would like to have a function run BEFORE, not after every top-level tasks. I think specifically to reset options(width = ) to accommodate to the current width of the console, using something like: options(width = system("tput cols")) I am sure there are many other situations where this could be

Modifying R_CheckStack for a speed increase
Greetings R developers, R will run a little faster when executing "pure R" code if the function R_CheckStack() is modified. With the modification, the following code for example runs 15% faster (compared to a virgin R-2.5.1 on my Windows XP machine): N = 1e7 foo <- function(x) { for (i in 1:N) x <- x + 1 x }

R callbacks
Hi, I'm trying to understand (mostly from the R-exts manual) how to use the callbacks declared in Rinterface.h. As a first attempt, I'm trying to redefine ptr_R_WriteConsole in a very trivial manner. Here's my code: --------------- $ cat altr.c int Rf_initialize_R(int ac, char **av); #define R_INTERFACE_PTRS 1 #include <Rinterface.h> extern int R_running_as_main_program;
