Hi all, Since three month ago I started working with R professionally, I never did it before, so I am such a newbie. I am having some problems using the 'debug' package. I love this package, but most of the times I wanna use it it just fails :P When typing at prompt 'mtrace(myfunct)' most of the times I get the following error: "Error in x[[i]] : subscript out of

Dear R-devel I have a function in a package that essentially provides a wrapper for a group of functions in another Suggested package (it sets appropriate defaults for the context, transforms output, etc). I've implemented this by verifying that the package was loaded with require(sna) and then do.call(snaFunName, args = args) The rDevel check is requesting that I use

Hello everybody, I'm trying to use a if-statment on a function. For a better understanding I want to present a small example: FUN=mean # could also be median,sd or any other function if (FUN == mean) plot(...) if (FUN == median) plot(...) ... This doesn't work, because FUN is a function. I've already tried to coerce the

See the bug for a reduction and the gimple trees. validate_arglist definately is rejecting the arglist in EmitBuiltinAlloca. (try: bool TreeToLLVM::EmitBuiltinAlloca(tree exp, Value *&Result) { tree arglist = TREE_OPERAND(exp, 1); if (!validate_arglist(arglist, INTEGER_TYPE, VOID_TYPE)) { debug_tree(arglist); return false; } Value *Amt = Emit(TREE_VALUE(arglist), 0); Amt =

Interestingly, in the .i file there are 2 __builtin_alloca, and EmitBuiltinAlloca is only being called once.

Hi all, I know it may not have much sense thinking about a Singleton Pattern in an R application which doesn't use any OOP facilities, however I'm curious to know if anybody faced the same issue. I've been googling but using "singleton pattern" as a key word leads to typical OOP languages like Java or C++ among others. So my problem is that I'd like to ensure some very

I have 2 calls to alloca generated: $ grep alloca x.bc|grep call %tmp21 = call i8* @alloca( i64 %tmp20 ) nounwind

I've come across a need to know whether an option was set true, false or unspecified. If it is true I want to do one thing, if it is false I want to do something else and if it is unspecified I want to do nothing. ArgList::hasFlag is a convenient way to check true/false with a default value. An ArgList::hasFlag that returned Optional<bool> would allow checking the unspecified case.

Hi, I have a function f <- function(..., func){ something }, where func is a function of the form function(...). ?I would like to pass func all the arguments passed to f except the last. ?I know that I can manipulate the variable number of arguments passed to f by converting ... to a list, i.e., arglist <- list(...). ?But how do I pass func the first n-1 list items of arglist (n <-

I added a couple of static probes to Firefox to measure actual work done. I could have used a pid$target probe with a function name but work is done within an if statement, which is where I placed the static probes. I''m wondering about my use, though. Is the following significantly more efficient than pid$target::FunName:entry and return? I heard somewhere that $target does not

Hi, I have question again about modifiers for pattern parameters. Vedant suggested such way. > CHECK-DEFINE-PATTERN: one_or_more(x): x {{+}} But I have some doubts. This should be equal to x+. This approach differs from standard one. In FileCheck I can write CHECK: {{x|y}}{{something}} This line will be equal to regex (x|y)(something). But if I use suggested approach and write same

Hi I want a function that takes precisely one named argument and no unnamed arguments. The named argument must be one of "a" or "b". If "a" is supplied, return "a". If "b" is supplied, return 2*b. That is, the desired behaviour is: R> f(a=4) #return 4 R> f(b=33) #return 66 R> f(5) #error R> f(a=3,b=5) #error R>

useRs, I'm using version 2.0.1 on Windows XP. I am a bit of a newbie and I am trying to learn the concept of computing on the language. I have an example that I think ought to work, but will not and I am not sure what I am doing wrong. I would like to sort a data frame by a list of columns. Eventually I would like to wrap this in a function so that I could sort data frames by a list

If anyone has a few extra CPU cycles to spare, I'd appreciate it if you could verify a problem that I have encountered. Run the code below and tell me if it crashes your R before completion. library(lme4) data(bdf) dump<-sapply( 1:50000, function(i) { fm <- lme(langPOST ~ IQ.ver.cen + avg.IQ.ver.cen, data = bdf, random = ~ IQ.ver.cen | schoolNR); cat("

Michael, I'm looking at flushing out the mach-o driver and targetinfo. Can we rename the "ld64" flavor to "darwin". The command line tool on MacOSX is called "ld" - just like on unix. The name ld64 is the current source repository name for the linker. Once lld takes over, the term ld64 won't mean anything. I've worked through adding DarwinOpts.td

Hey All, I’m working with Mac OS X 10.10, and everything seems generally fine but when I started working on a FunctionPass I get the following: error: call to deleted constructor of 'Function::ArgumentListType' (aka 'iplist<llvm::Argument>') Function::ArgumentListType argList = f.getArgumentList(); Any pointers as to the correct way access the Arguments of a

The following works fine with the x11 device, though it may well be that an initial plot is overwritten. With a pdf or postscript device, I get two plots, the first of which still has the red border from having the focus, while the second is the plot that I want. library(lattice); library(grid) plt <- xyplot(uptake ~ conc, groups=Plant, data=CO2) print(plt)

I get an error when using self-defined (not standard) functions with mapply with S4 objects from the raster package that I develop: "Error in as.character(sys.call(sys.parent())[[1]]) : cannot coerce type 'closure' to vector of type 'character'". Does anyone understand why? The problem is illustrated below. Thanks, Robert > # First a general example that works

Hello Folks, Is there any way to pass a list into a function such that the function will use the list as its arguments? I haven't been able to figure that out. The background: I'm trying to build a function that will apply another function multiple times, each time with a different set of specified arguments. I'm trying to figure out how to pass in a list of argument lists, then
