I like Sweave, which I consider to be a great contribution. I have just written a .Rnw document that comes to about 6 pages of mixed code and mathematical explanation. Now I want to turn the R code into a function. My R code currently contains statements like N<-1000 and theta<- pi/10. In the next version of the document, I want N and theta to be parameters of a function, so that they can be

Hi, I am expieriencing strange behaviour of llvm's optimization passes and I don't understand what I am doing wrong. Basically all I've done is extracting code for optimization of a llvm-function in a llvm-module and put it into a separate function for better readability. The original code looks like follows (and works as expected): ----------------------------- std::string

Hi, supposing I have a function “foo” like the following: int foo(int a, int b) { ... ... } I want to insert int the LLVM IR a call instructions to a function “bar” that requires the same parameters of foo. So my function foo will become: int foo(int a, int b) { bar(a,b); … ... } I am using the following code: bool ThreadSanitizer::runOnFunction(Function &F) {

I'm trying to move from Matlab to R, and I'm stuck even getting started. This sounds to me like the dumbest question in the world but... how does one put R source code in files? Over the last three days I've gone front to back through the Introduction to R and the R Language Definition, and while I'm excited that the language is so Lispish, none of what I read described how to

Full_Name: Adriano Azevedo Filho Version: 2.9.0 OS: Windows Vista Submission from: (NULL) (201.68.79.62) The error message produced when the function name typed in the console is misspelled in the Portuguese translation. This is not a new issue but as it is around for sometime I've decided to report. As this is a frequent message when beginners start using R, it gives an unfortunate bad

Within a function I'd often like to obtain a text string equal to the name of the function. One use for this: To generate a filename for use in pdf(). This enables me to keep track of which function generated a particular graphic came. match.call() puts parentheses at the end of the name. I don't want parentheses in a filename. The following kludgey function gives the desired result.

I just upgraded from 2.8.1 to 2.10 on Windows Vista. BIG MISTAKE apparently because now when I type: > help(functionname) or ?functionname I get only a small text window giving some very basic info on the topic, e.g.: base-package package:base R Documentation The R Base Package Description: Base R functions Details: This package contains the

Hi folks, I’m working on adding an API for incremental updates to DominatorTree and I noticed that there isn’t a simple way to quickly build and update CFG (just for testing) -- one has to either build CFG programmatically, or write IR by hand and manually map pointers to basic blocks. The downside is that it tends to be pretty verbose and not easy to update (e.g. adding a new edge often involves

If users post a bug or problem issue to an R-based news group (R-devel, R-help, BioC - though BioC is far more forgiving) they get yelled at for not reading the posting guide and FAQ. "Please *_do_* read the FAQ, the posting guide, ..." the yellers do say. So I read the BioC FAQ and it says... http://www.bioconductor.org/docs/faq/ "Bug reports on packages should perhaps be

Readers, I am having difficulty understanding how to enter commands into r. I have data arranged as: 100, 200, 300 5.6, 6.7, 7.8 8.9, 9.0, 0.1 1.2, 2.3, 3.4 The data is saved in csv format and I use the command 'read.table' to import into r. The values 5.6...3.4 are a function of values 100,...300, i.e. 100,...300 are independent variables (x). The function is a power series:

Ok, so calling lle_X_FUNCTIONNAME instead of FUNCTIONNAME works (is there any reason the post used the lle_X_ prefix other than convention? was it once possible to call external functions as I was originally trying, or, why did the blog post think it was possible?) I'm now running into trouble when trying to access arguments however. printing args.size() from the function yields

The blog post I linked to implied that adding a symbol in the form lle_X_FUNCTIONNAME would allow you to call a function called FUNCTIONNAME. Is this not the case?

There is quite a long piece of code defining a certain function in one of the R packages. I think the code has a bug and I want to get the code into a file so that I can take a proper look, and possibly fix it. how does one do this? (I mean getting the code into a file, not fixing the bug.) I suppose I could copy and paste, but that's a bit error prone for various reasons. I want the same

Hello, [Using LLVM r155315, according to `svn log | head`] I am experimenting with programatically building and jitting functions in a module, and I seem to be coming across a crash in some generated code. Using the llvm-c interface I build up the module which dumps like this: ; ModuleID = 'MyModule' target datalayout = "i686-apple-darwin11" target triple =

Dear all, I've written a (quite long) function in R. While running it I get the following error message: Error in "[<-"(`*tmp*`, 1, 13, value = NULL) : number of items to replace is not a multiple of replacement length operation failed in: function () !!! evaluation not successful!!! How to interpret this error message? (There aren't any expressions that

Hi David, I'm not certain, but to me the "LLVMSetTarget(module, "i686-apple-darwin11");" line looks suspicious. I'm not familiar with all the ins and outs of how target triples get handled, but it looks to me like that's requesting 32-bit code. I think that if you omit that line completely then the target will be inferred from the execution environment. My best

dum is a simple data frame transferred to Splus using the dump() command in Splus and the source() in R. All fields are numeric. There are no missing data. The data frame looks like it is should: > apply(dum,2,mode) yrcl sland s02 s234 "numeric" "numeric" "numeric" "numeric" > apply(dum,2,is.vector) yrcl sland s02 s234
