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

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

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

Dear List: Sorry for posting maybe a trivial question, but I have a basic understanding problem. If I have say pack1 and pack2, two R packages, and pack2 depends on and imports pack1 fully (as in the code below), is there a way to make all the functionality of pack1 available for the global and other environments (not only for the functions called from withing pack2) by loading pack2 only? I

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

Dear developers: I have just came across an (unexpected to me) behaviour of lists when assigning NULLs to list elements. I understand that a NULL is a valid R object, thus assigning a NULL to a list element should yield exactly the same result as assigning any other object. So I was surprised when assigning a NULL in fact removed the element from the list. Is this an intended behaviour? If

Hi Community, here is the problem, Linux problem (reported to work on Windows). I need to generate graphical output in any of bitmap format under the 'R CMD BATCH'. Whereas the script generating png-s works perfectly in the R session, such things as X11, png and jpeg are not usable in BATCH (they cannot be switched on by --gui-X11 etc) and X11 is prompted to be required for png.

Hi everyone, I am not sure this is possible so I would be interested in your responses. Say I have a variable 'v' with the string "myargument" in and I have a function 'f' that takes this argument as follows; f <- function( myargument=5 ) { ... does something... } Is there anyway I can say something like; f( v=10 ) such that it will be evaluated as f(

Hi, I am not sure if this is just me using R (R-2.3.1 and R-2.4.0) in the wrong way or if there is a more serious bug. I was having problems getting some calculations to add up so I ran the following tests: > (2.34567 - 2.00000) == 0.34567 <------- should be true [1] FALSE > (2.23-2.00) == 0.23 <------- should be true [1] FALSE > 4-2==2 [1] TRUE > (4-2)==2 [1] TRUE >

Hi, I have been studying the R manual on lists but cannot seem to create a simple R list in C - I keep on getting "'dimnames' applied to non-array" whenever I attempt to assign names to the list elements: Wanted output a list structure something like [ type="Bid", price=2.0, volume=1000 ] I can get up to a list of [ "Bid2, 2.0, 1000 ] But for the life of

Hi Community, I have a question about how to pass command line parameters to R script running in the batch mode. The problem is: there is a banch of data files which are to be processed by R script called from a web-server, i.e. in the batch mode. The web server generates data files and passes their names calling 'R CMD BATCH' one by one for every file. Now the question is how to

Dear list: I would like to override the default way R formats plot axes with a custom method(s). Obviously I would prefer to define it as general as possible avoiding writing a custom method for each individual class where possible. The plot.default method (and I assume other methods as well) calls Axis(...) to produce the axis layout depending on data. In this sense it seems reasonable to

The XML package relies on libxml2.dll (e.g., bundled with the CRAN binary) installed in library/XML/libs. Unfortunately, c:/WINDOWS/system32/libxml2.dll will be found and loaded before this. Is there any programatic solution? Thanks, Martin -- Martin Morgan Computational Biology / Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N.

Dear lists: I am somewhat puzzled by the use of texi2dvi/pdflatex in R2.7.0. When building EBImage (bioconductor) with 2.7.0 I get the same error both in Windows and Linux, which reads the following: ** building package indices ... * DONE (EBImage) * creating vignettes ... ERROR /usr/bin/texi2dvi: pdflatex exited with bad status, quitting. Error in texi2dvi(file = bft, pdf = TRUE, clean =

Dear developers, has anyone experienced the problem described below? Is it a bug in handling interrupts in R?

Hi, I do not know if everybody finds index pages of the html-formatted R help useful, but I know I am at least not the only one who uses them extensively to get the overview of functions and methods in a package (even for my own package). Problems arise, however, if a lot of S4 methods need to be documented blowing out the index with (generally irrelevant) entries like:

Hi Everyone, I have a problem using some working 32-bit R code with 64-bit machine ( I am using version R-2.4.1 ). The problem occurs when I am trying to detect a NULL STRSXP type. ( Perhaps I am doing this detection in the wrong way? ) On 32-bit the following works, and correctly identifies if I am passing NULL or a valid string object: if ( v_dta_start != R_NilValue && STRING_ELT(
