Suggestion on how to make permanent changes to a single object in a list?
specifically, imagine we have: fooStack <- list() for ( i in 1:5 ) fooStack[[i]] <- list() and we have a function: fooModifier <- function( foo ) { foo$bar <- "bar" } then, if we invoke fooModifier, i.e.: fooModifier( fooStack[[ 1 ]] ) the $bar elt is only set in the scope of the function, and if we use the

Running R under Sun Grid Engine with OpenMPI tight integration
Hi - I saw your posting on the R-help mailing list. Were you ever able to get this working? did you end up switching to use the rsge library? I'm trying to do the same, and not having very much luck getting it going. Thanks! Peter Waltman [[alternative HTML version deleted]]

Memory leak with character arrays?
Hi - When I'm trying to read in a text file into a labeled character array, the memory stamp/footprint of R will exceed 4 gigs or more. I've seen this behavior on Mac OS X, Linux for AMD_64 and X86_64., and the R versions are 2.4, 2.4 and 2.2, respectively. So, it would seem that this is platform and R version independant. The file that I'm reading contains the upstream regions

Possible memory leak with R v.2.5.0
I'm working with a very large matrix ( 22k rows x 2k cols) of RNA expression data with R v.2.5.0 on a RedHat Enterprise machine, x86_64 architecture. The relevant code is below, but I call a function that takes a cluster of this data ( a list structure that contains a $rows elt which lists the rows (genes ) in the cluster by ID, but not the actual data itself ).

How to remove/prevent trailing space after tab completion in R shell
Hi - Not a mission critical issue, but still highly annoying. I just upgraded R to 2.10.0 (the binary for Ubuntu karmic) and the tab completion facility now inserts a space after every completed term (something it didn't do in 2.9.0 or 2.9.2). It wouldn't be an issue so much if it weren't for the fact that it screws up tab-completing the next term, i.e. if I have a list of lists of

how can I attach a variable stored in
Hi - Any help would be greatly appreciated. I'm loading a list variable that's stored in an .RData file and would like attach it. I've used attach( <file_name> ), but that only lets me see the variable that's stored in the file. As the variable name is of the form "comp.x.x", I've tried using attach( ls( pat="comp" ) ), but get an error as ls()

Suspected memory leak with R v.2.5.x and large matrices with dimnames set
Hi - Admittedly, this may not be the most sophisticated memory profiling performed, but when using unix's top command, I'm noticing a notable memory leak when using R with a large matrix that has dimnames set. To allow people to reproduce the problem I'm seeing, I've added a small (< 50 lines) code snippet at the end of this email. I'm seeing this

Parametrized object name in Save statement
Greetings All, I am looking to write a parametrized Rscript that will accept a variable name(that also is the name of the flat file), transform the data into a data frame and preform various modeling on the structure and save the output and plot of the model. In this example i am using a rpart decision tree. The only problem i am having is integrating the parameter into the internal object name

Get segfault with ModulePass
Hi, don't know if this is the right list. Please post a better place, otherwise. I'm currently writing a LLVM ModulePass and ran into strange segfaults or endless loops within LLVM. My main question is, if this is a programming error or API misuse from me or a LLVM bug? Here is some minimal code, that triggers the bug: ---------------- class DebugPass : public ModulePass { public:

[LLVMdev] Pulling line number/file/path information from DbgStopPointInst instructions
Hmm... if I do a print() on the result of getFileName(), I get i8 * getelementptr ([9 x i8]* @.str, i32 0, i32 0) back, but if I try to dyn_cast this to GetElementPtrInst it fails (returning null), so presumably I'm seeing a GetElementPtrConstantExpr... so how can I get at that constant i8 array without casting to a GetElementPtrInst, and with GetElementPtrConstantExpr being

[LLVMdev] DebugInfo from LLVM Instruction
Hi all, I used to extract the debug information from an LLVM Instruction in the following way: if (MDNode *N = I->getMetadata("dbg")) { // Here I is an LLVM instruction DILocation Loc(N); // DILocation is in DebugInfo.h unsigned Line = Loc.getLineNumber(); StringRef File = Loc.getFilename(); StringRef Dir = Loc.getDirectory(); } As specified also at

[LLVMdev] Pulling line number/file/path information from DbgStopPointInst instructions
Hi folks, I had some code that used to work fine in earlier versions of LLVM, but is now failing. I have some code that expands DbgStopPointInst instructions to my own entry points in an opt pass, but it's currently failing to get the file name and path back, though it is still correctly getting line numbers.

how to add the location debug info for each instruction
Hello, For some reason, I have to stick on llvm 3.3 for a language compiler, I find that the location debug info is attached to each instruction using !dbg, however, I found some of that information is mis-attched and need to be changed, so I want to *know what functions(I checked all funcs in DIBuilder.h but didn't find a appropriate one) are used to attach those !dbg nodes to each

relative file path
Hello, Is there a way to find where a script is located within a script? getwd() doesn't do what I want because it depends on where R was called from. I want something like source("randomFile") and within randomFile there is a function called whereAmI() which returns c:\blah\blah2\randomFile.R In perl there is a library called FindBin and $FindBin::Bin has the directory of the file

[LLVMdev] How to read v3.3 dbg metadata using v3.4 LLVM
Thanks Eric, but could you give me a little bit more hints or pointers please? I looked into DebugInfo.h, but I'm still not sure how to start. It sounds like I'd have to somehow manually extract metadata nodes from an instruction.
