Questions about Preserving registers
Hi folks, I tried to use Mirosoft Fortran Powerstation 4.0 to create a dll file. However, when I used the command dyn.load(“test.dll”), I got the following message: NULL Warning message: DLL attempted to change FPU control word from 9001f to 90003 I read the instruction on Duncan Murdoch’s website about preserving registers, but I still don’t understand it. For example, 1. On first entry

Data table in C
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"

Retrieving function name
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

String to list and visa versa
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

Ralloc clash
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

variable problem
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(

Speed of for loops
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. >

Manipulating R lists in C
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

Floating point maths in R
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 >

Read.table for macs
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

Overloading functions
Hi Everyone I have a function f which does something using a function g. Function f is in a library and g has a default stub in the library but will be mainly overloaded in a later R script. For example: ########## In a compiled package 'P' ################# g <- function() { cat("Original function g"); } f <- function( newGsource=NULL ) { if(

Simple example for High performance computing with R?
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,

Problem with types on 64-bit
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(

Cross compiling a package for Windows on Linux
I would like to compile for Windows a rather simple R package that contains some C code. It does not contain any Fortran code. I tried the cross-compilation route using the pre-built set of tools from http://www.devolution.com/~slouken/SDL/Xmingw32/, as described in $R_SRC/src/gnuwin32/INSTALL Using the sources in r-devel from the rsync site I am able to build libR.a in src/gnuwin32 but I
