Hi all, I know I shouldn't really expect the following to work, but it provokes a crash of the GUI on my computer (Win xp professional). --- >sessionInfo() Version 2.3.1 (2006-06-01) i386-pc-mingw32 attached base packages: [1] "methods" "stats" "graphics" "grDevices" "utils" "datasets" [7] "base"

Hello all, Since I got no answer to my first mail, I suspect I did not formulate my question adequately, so I try again. In R, one can debug or trace a function 'foo' with debug(foo) or trace(foo), respectively. This leads to a special treatment of the function 'foo' until one enter undebug(foo) or untrace(foo). I would like to know if there is a convenient way to know at any

How do you debug methods of a reference class? I've been using mtrace, which is excellent, but i cannot figure out how to mtrace a reference class method. Maybe there is some other way to debug these, for example with ordinary trace? for now i am only able to use options(error=recover), which is not giving me idea where exactly in the code i am once i am stopped on an error. -- View this

Dear R-devel, I don't think this is expected : foo <- function() "hello" trace2 <- function(fun) trace(fun, quote(print("!!!"))) base::fun # Object with tracing code, class "functionWithTrace" # Original definition: # function() "hello" # # ## (to see the tracing code, look at body(object)) `untrace()` has the same behavior. This is

Please note that this is documented in ?trace. "fun" is matched to what, it is a _name_ of the function to be traced, which is traced in the top-level environment. I don't know why it was designed this way, but it is documented in detail, and hence the expected behavior. Debugging is often, and also in R, implemented in the core. Tracing is implemented on top without specific

Merry Xmas to all, I am writing a function and curiously this runs sometimes on one data set and fails on another and i cannot figure out why. Any help much appreciated. If i run the code below with data <- iris[ ,1:4] The code runs fine, but if i run on a large dataset i get the following error (showing data structures as matrix is large) > str(cluster.data) num [1:9985, 1:811] 0 0 0 0

We have had some conversation within R core, lead by Duncan Murdoch and me, about a proposal to extend the current tracingState() functionality by something tentatively called debuggingState(). Duncan has allowed me to copy the previous conversation (after very minor editing): The following is quite technical and assumes you know more about R's debug()ing and trace()ing than an estimated

Hi Tomas, The doc indeed describes `what` as "the name, possibly quote()d, of a function to be traced or untraced". This is a good argument not to change the function and make it behave more like debug. However the doc also tells us "A call to trace allows you to insert debugging code (e.g., a call to browser or recover) at chosen places in any function" and "The trace

Hi, I am trying to implement a scenario similar to running ExceptionDemo.cpp with parameter -1 (where the JITed code calls the C++ function which throws an exception) Different from the given example I am using IRParser instead of IRBuilder. I can successfully catch the exception in Linux but the program crashes in Mac and Windows. The code is similar to as follows: ### The test.cpp :

I run checks with R-devel rev. 76756 on several of my packages which use S4, with no ill effects. With the risk of not adding much, it seems that Martin's example, which I repeat below, suggests a crossover between several "signatures" involved here - the signature of the generic, the signature of the method (the argument for setMethod()), and the signature of the function object

Hi Joshua, I have a function foo and I want to insert exit(0) at the end of foo. The problem is M.getFunction returns null, which is understandable. I am not sure what to do. Below is the code snippet. void foo(int argc, char* argv[]) { printf("hello world\n"); exit(0); //***I want to insert this exit } My llvm code snippet is vector<const Type *> params =

Hi! I am trying to develop an LLVM tool which can apply different optimizations for selected functions. For example, I want to apply an optimization onto one function but not for another one. I am using the standard optimizations available in LLVM. That is the runOnModule function I have written: bool ComplNewBBFuncs::runOnModule(Module &M) { Function *Main =

Dear Ashutosh, Thank you, I can handle some indirect callSites by getFunction() of InvokInst and CallInst. However, when I am handling C++ programs, I found the calls of member functions are converted to some strange indirect calls. For example: table->truncate(sysTransaction); // from mysql are translated to the next complex llvm IR: _ZN8Database20getSystemTransactionEv.exit: ;

Hi, I am trying to replace a c-style function with another function with same signature. Consider the following code: std::stringstream main_c; main_c <<"#include <stdio.h>\n" <<"extern \"C\" { \n" <<"int print1()\n" <<"{\n" <<" printf(\"Inside
