Hi I'm having slight confusion. I plan to grow/realloc a matrix depending on the data available in a C program. Here is what I'm tried to do: Data=allocMatrix(REALSXP,3,4); SEXP Data; REAL(Data)[8]=0.001123; REAL(Data)[200000]=0.001125; printf("%f %f\n\n\n\n",REAL(Data)[8],REAL(Data)[200000]); Here is my confusion: Do I always require to allocate the exact number of data

Hi I'm getting the following errors while using the efficientPortfolio function even though I'm setting the target return to the mean of the TargetReturn I obtain from the portfolio object created by the feasiblePortfolio function. First Error: Error: targetReturn >= min(mu) is not TRUE Second Error: Error in .rquadprog(Dmat = args$Dmat, dvec = args$dvec, Amat = args$Amat, :

Hi I think I have asked these questions earlier, but I been able to find answers from the documentation (which I found poorly written in several places). Will someone be kind enough to give me answers and enlighten me? (as in explain with CODE?) I want to embed R in my application and use the fPortfolio package for carrying out risk management computations. Right now I'm reading the Rmetrics

Hi I am unable to try out examples from the Rmetrics Ebook from the R command prompt. Below is an example of what happens: > Covariance<-cov(SWX.RET) Error in cov.timeSeries(SWX.RET) : no slot of name "Data" for this object of class "timeSeries" I have loaded Rmetrics and fPortfolio using the library function but still I get these errors. However, if I embed the R

Hi I seem to have run into a situation where I have more than 3 arguments to pass to a function from C. the following functions help me build an expression for evaluation: lang lang2 lang3 lang4 What should one do if there are more arguments than lang4 can handle?

I tried to download/compile/install win32-dir, but I couldn''t get it to go. Over a private email Daniel Berger had me... "Curious. What platform are you on exactly? Try modifying the extconf.rb file. Add ''have_library("SHFolder")'' above ''have_library("shell32")''. If that doesn''t work, try uncommenting the other

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

Hi Ross.. I can email you the sources (complete zip is about 5Mb..with all the dependency directories etc) and all you have to hit is build after that. Would appreciate help in getting it going.

Indeed, it's 32bits x86 and there's no .safeseh or anything like it, even readobj -coff-load-config says nothing: File: ConsoleApplication830.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit Now I know what to look for, thanks!

Hi Abhijit I can't answer your questions but I would be very interested in a fully working binary of Ices2 for Win32 once it's ready. Thanks for the effort.

I am trying to port some C code from S-Plus (7.0.6) to R (2.4.0) under Windows XP SP2. I use Visual C++ 6.0 to build my library for S-Plus, so I'd like to stick with that set up, if possible. According to the README.packages file, I need the file R.exp (containing functions exported from R.dll, I'm guessing) to build an R package with VC++. >From what I've read in the archives of

Well...since this is a port to Win32 patches may not make sense. Pathnames to the required libraries are relative, but hardcoded from the point of reference. Without that, it will not build. Since there are lot more files (related to the IDE as well as some project build settings which link to libraries in Win32) which have no close equivalents in the non-Win32 world. Hence can't do patches.

I would like to utilise the power of R by adding my own software as a package written in C++. As a first step I am trying to write a DLL with a simple function that can be called from R. The DLL contains a C++ routine written and complied in Microsoft Visual C++ Ver 6.0 and is based upon the example in R-Exts eg I am trying to create the following example function SEXP out(SEXP x, SEXP y) {

Hi, I'm getting: Unhandled exception at 0x00C211F0 in ConsoleApplication830.exe: 0xC00001A5: An invalid exception handler routine has been detected (parameters: 0x00000001).

Hello.. I have libshout2, ices0-3 and ices2 compiling on Win32 with MSVC++ 6.0. However, I don't know where to upload the code and if someone is kind enuff to point out the location(s)/procedure that would be great. I will put a readme in the distro for compiling procedures. ices2 compiles but doesn't run correctly (yet). There are some issues related to parsing the ices-playlist.xml

It looks like win32-api, both 1.0.5 and the latest in CVS, are segfaulting when I build with VC++ 8 or later. Both work fine with VC++ 6, though. Thinking it might be strncpy_s, I removed that, but it didn''t help. I installed a fresh Ruby built with VC++ 8 as well, but that didn''t help either. Loaded suite C:/rubyvc8/lib/ruby/site_ruby/1.8/rake/rake_test_loader Started

I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

Hi all, While testing my compiler on win32 in JIT mode, I ran into a couple of issues: 1. I linked the compiler with the lib files resulting from the cmake created VS.NET build. While everything built just fine, the ExecutionEngine::create call always returned NULL. The fix was to also link with JIT.obj (thanks aKor for pointing me in the right direction). I would have thought that linking
