Hi everyone, I am trying to cross-compile a package I wrote using the Yan and Rossini tutorial "Building Microsoft Windows versions of R and R packages using Intel Linux". I have got reasonably far with this but when doing the linking using the line: i586-mingw32-g++ -shared -s -o mylibrary.dll mylibrary.def mylibrary.o mylibrary_res.o

Dear All, I've been using R for windows for a while, without too many problems. However, I'm forced to use the MAC OS system for teaching, because our teaching labs are mac only (not my idea!!). I have a very basic problem, but one that doesn't appear on the FAQs. I simply want to import data from a spreadsheet. I'm using exactly what works fine on Windows, namely: 1 save

I'm attempting to reflect the information for use with corresponding fields in GUI (in a different package), to provide default values, argname as key for UI label lookups, etc. So I want something much more like the formals of the implementation: { "object", "method": c("median", "vs", "tukey"),

What a delicious example! (I'm taking the liberty of sharing it with r-devel, since it raises some good issues.) You have two questions, presumably: 1 - how could the order of the setMethod calls make a difference in the results? 2 - what's causing the infinite loop & how could it be avoided, reliably? Second question first. The danger sign is the "vector" method:

Hi, I need to collapse a list into a string and then reparse it back into the list. Normally when I need to do this I simply use write.csv and read.csv, but I need to do this in memory within R rather than writing out to file. Are there any bespoke commands that any knows of that does something like this or any tips for doing this that anyone can suggest? I basically don't care

After getting one list done, I am now struggling to form a data frame in C. I tried to do a list of lists which gives me : $<NA> $<NA>[[1]] [1] "BID" $<NA>[[2]] [1] 0.6718 $<NA>[[3]] [1] 3e+06 $<NA> $<NA>[[1]] [1] "BID" $<NA>[[2]] [1] 0.6717 $<NA>[[3]] [1] 5e+06 $<NA> $<NA>[[1]] [1] "BID"

Hi, Does anyone know how I can retrieve a function name, for example If I have a function f as follows: f <- function( myfunc ) { print( name_of(myfunc) ); } I want to know what I should have as "name_of" such that I could call this with : f( median ) and it would print "median" or f( my_function_name ) and it would print "m_function_name". So far all I

Hi everyone, Now I know there is information on this in the help files - which I have read. I am very close to implementing this but can't quite get how to remove this final hurdle. I have a DLL called "X.DLL" which I have no original code for, just the DLL. I have created a wrapper C file for the calls in X.DLL, and have successfully (I think) created a wrapper DLL for X

Interrogating some (of my own) code in another package. >norm.meth <- getMethod("normalize", "MatrixLike") >message("str(norm.meth)") >str(norm.meth) >message("show(norm.meth at .Data)") >show(norm.meth at .Data) Last show() displays this: function (object, ...) { .local <- function (object, method = c("median",

Hi everyone, I''m a bit new to rails, but I have played around with it for the last month. I really enjoy programming in rails and I feel that I should program my new application through this framework. I am very exited when I start creating my scaffolds and views, there is some sense of accomplishment. Now I would really like to make a search function my page that would search through

How would one go about getting sprintf to use the values of a vector without having to specify each argument individually? > v <- c(1, 2, -1.197114, 0.1596687) > iv <- c(3, 1, 2, 4) > sprintf("%9.2f\t%d\t%d\t%8.3f", v[3], v[1], v[2], v[4]) [1] " -1.20\t1\t2\t 0.160" Essentially, desired effect would be something like: >

Dear list, I want to run two independent calculation (A, B) and then combined their results to do a plot in R. Before I just run calculation A first, then calculation B. It will take some times. I just have one server with multiple core. I noticed that there are some nice package in R for parallel calculation, such as parallel, multicore and snow. Also there is a book, O?Reilly ? ?Parallel R,

What's the best way to simulate Recall for parent function? Consider this one-time recursive code: alwaysEven <- function(x) { handleOdd <- function(x) { alwaysEven(x-1) # use Recall-like here } return(if (x %% 2) handleOdd(x) else x) } any2even <- alwaysEven rm(alwaysEven) any2even(3) ---------------------------------------------------------- SIGSIG --

Can the value of a list element be referenced from a sibling list element during list creation without the use of a temporary variable? The following doesn't work but it's the general idea. > list(value = 2, plusplus = $value+1) such that the following would be the output from str() List of 2 $ value : num 2 $ plusplus: num 3

Hi everyone, Have been trying to include windows.h (from MinGW) and R.h into a package and have found that Ralloc is coming up as a clash no matter which include ordering I use. In windows it has 2 arguments and is defined in objidl.h and in R.h it is 3 arguments. Any ideas of how to work round this? Have checked the web and have not seen anyone else comment on this. Many thanks Tom

Hi Everyone, I have a question about for loops. If you have something like: f <- function(x) { y <- rep(NA,10); for( i in 1:10 ) { if ( i > 3 ) { if ( is.na(y[i-3]) == FALSE ) { # some calculation F which depends on one or more of the previously generated values in the series y[i] = y[i-1]+x[i]; } else { y[i] <- x[i]; } } } y } e.g. >

Agreed, definitely. The current hack is to avoid re-matching arguments on method dispatch, so a fix would need to be fairly deep in the

Was looking at what was output for <pkgname>-package.Rd and wondered if any there was any means (via macro, etc) to merge some of the same information with a template for my package manpage? As much (all?) of the generated information was already provided in the DESCRIPTION, I'd prefer not to have to update the information in multiple places. I'm thinking here that I could provide a
