How can I generate a vector of differences between each elemtn of an vector? i.e. a[i]=x[i]/x[i-1] -- View this message in context: http://n4.nabble.com/Deltas-or-changes-tp1585960p1585960.html Sent from the R help mailing list archive at Nabble.com.

This does what I was hoping it would: aggregate(tm[,-1],by=list(tm[,10]),FUN="mean") but I don't know what "tm[,-1]" means (well - the -1 bit anyway. Does it somehow means the whole matrix?

After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

ok.. So I am trying out what you have suggested. I have written the below code which basically tries to write the constant 10 to a file. myprint is a function pointer to a function which takes char * parameter and writes it to file. Value *Ten = ConstantInt::get(Type::Int32Ty, 10); const Type *VoidPtrTy = PointerType::getUnqual(Type::Int8Ty); AllocaInst *AI = new AllocaInst(Type::Int32Ty); Value

Dear R experts, I've written some functions in a few source files (such as main.R, control.R ...). After loading them into R, how do I retrieve which functions are loaded from which source file? For example: main.R has functions: myPrint(), myScan() control.R has functions: setPrinter(), setData() After loading the sources (main.R and control.R) into R, I would want to know that

Ah! I get it now. Thanks a lot ! I changed it to BitCastInst(AI,VoidPtrTy,"",j); And now I am getting the following error :(. I have been stuck with this error before also. I know I am missing out something silly. What is the cause of this error and Please let me know how to fix it. /home/bhavani/llvm/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp:1130: llvm::SDOperand

Thanks Nick! ok. I ran through the verifier and this is the issue: verifying... Instruction does not dominate all uses! %tmp3 = add i32 %b, %a ; <i32> [#uses=2] store i32 %tmp3, i32* %0, align 4 Broken module found, compilation aborted! add is existing instruction in function. store is the instruction I have added to the function. How do I fix this now :(? Thanks, Bhavani --- On Mon,

People, I'm a ubunto user and I used to write my scipts in "Java Gui for R", but it is a very slow tool to run my scripts... Do you know some efficient IDE for R? Thankssss!!! Alexandra Almeida -- Alexandra R M de Almeida [[alternative HTML version deleted]]

Hi, I am writing an optimization pass where I need to instrument the code such that I need to store the results of some instructions in file. Using llc -march=cpp option I figured out how to add a function(say writeToFile) which takes char* parameter and writes to file. Now, I need put in a CallInst which calls writeToFile passing the Instruction result as parameter. How do I do this? So, in my

I have searched and tried to read before posting but can find nothing to accomplish change Excel dates in double format to R Can someone please help I have a vector of double like this from Excel. 39965.0004549653 and I want to put them in R such that I can display them in any Date and Time format. as.Date does it ALMOST but chops off the fractional seconds. POSIXct doesn't appear to do

I have a matrix with a POSIXct as a numeric in the first column. I would like to create a new matrix that is "grouped by" my chosed time bars. i.e. So I would like to group by hour or day or 5 days, and have all my columns be summed or averaged or counted.. mydata: V1,V2,V3 10:03:13,3.4,1002 10:03:14,5.6,1001 10:05:27,7.2,999 10:05:33,8.2,998 I want to convert this into say 5

How do I get a number representing a date from a POSIXct i.e. removing the time elements? -- View this message in context: http://n4.nabble.com/how-to-return-date-part-of-POSIXct-tp1598109p1598109.html Sent from the R help mailing list archive at Nabble.com.

Hi Everyone, I want to generate IR for the following C code printf("Hello World!"); To insert a printf call in the IR, I use Function* myPrint = M.getFunction("printf"); to get the function from my symbol table. Once I have the function to make a call to this function I use CallInst::Create(myPrint, args.begin(), args.end(),"", B); But I am not being able to

I am parsing dates as follows: > z[1:10,1:3] V1 V2 V3 1 0 03/02/09 22:20:51.274 2 100 03/02/09 22:28:18.801 3 200 03/02/09 22:33:33.762 4 300 03/02/09 22:40:21.826 5 400 03/02/09 22:41:38.361 6 500 03/02/09 22:42:50.882 7 600 03/02/09 22:45:19.885 8 700 03/02/09 22:48:55.558 9 800 03/02/09 22:51:21.112 10 900 03/02/09 22:58:41.860

Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

Hi, A number of people have suggested "I read the manuals"... Could someone help me by telling me where the primary start point is please? For example, I am interested in writing functions with variable number of arguments - where should I start to look? "An introduction to R" only show a brief example - with no pointer to where to find further data. I can't do ?xxx

Thanks a lot Nick -march=cpp was very helpful. But I still have a small problem, I am trying to insert a printf in a transformation pass. So when the original program already has a printf, on executing the transformation pass, it tries to create function "printf1" instead of "printf" Am I missing something here? Thanks again!
