similar to: reinventing the wheel....

Greetings! I have a few colleagues who like the idea of Sweave, but have failed to become enlightened monks of the One True Editor (http://www.dina.dk/~abraham/religion/) Are there any other Microsoft-centric editors or IDEs which have solid support for writing SWeave documents (dual R / LaTeX enhancements similar to ESS's support)? Has anyone tried the folding editors which support Noweb?

R-devel, SVN revision 35729 (this morning, euro-time) So far, I'm having awful luck with the "installWithVers" flags. Recent example: I can install.packages("lattice", installWithVers=TRUE) successfully (no errors, at least it looks like a successful install), but can't load it: Error in library.dynam(pkg,pkg,lib) : shared library 'lattice_0.12-7' not found

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():

Has anyone taken a shot at a Cairo graphics device yet? I half expected to see one on either Paul's pages or Omegahat. :-) --- Byron Ellis (ellis at stat.harvard.edu) "Oook" -- The Librarian

Well, nothing has changed in the issues that I brought up earlier, except that I can confirm core dumps in non-threaded lisps as well (CLISP), using svn version 37840 (this morning, Seattle time) for R-2-3-patches. I've not tried Thomas' suggested fixes, as I'm hesistant to go down the road of fixing R in such a way that would require constant patching. (so for those counting,

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

For those who suggest other ways to do this, I ALREADY HAVE ANOTHER DESIGN SOLUTION, DESCRIBED AT THE END. That being said, I want to know if it's possible to reference a slot in an S4 class from another slot, i.e. I'd like to have the "self.*" semantics of Python so that I can reuse a slot. That is, for various reasons it would be nice to be able to do something like:

I will say this first -- I can't copy/paste the error message from the screen, so it's being retyped. Errors might occur. SORRY. I've been experiencing some interesting stack warnings recently when moving from R 2.2.x to the R 2.3.0 series and the R 2.4.0 series. In particular, I'm getting warnings of "Error: C stack usage is too close to the limit" before

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

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...

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'. Any clues to where this

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

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

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 }

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;

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

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
