Hello, (This is follow up from this thread: http://www.nabble.com/execution-time-of-.packages-td22304833.html but with a different focus) I am often confused by the result of the profiler, when a loop is involved. Consider these two scripts: script1: Rprof( ) x <- numeric( ) for( i in 1:10000){ x <- c( x, rnorm(10) ) } Rprof( NULL ) print( summaryRprof( ) ) script2:

I'm picking up this 5-year old thread. 1. About the four memory allocations without a stacktrace I think the four memory allocations without a stacktrace reported by Rprofmem(): > Rprofmem(); x <- raw(2000); Rprofmem("") > cat(readLines("Rprofmem.out", n=5, warn=FALSE), sep="\n") 192 :360 :360 :1064 :2040 :"raw" are due to some

I noticed this oddity about R profiling and setMethod. First, I "test out" Rprof. > require(methods) Loading required package: methods [1] TRUE > > Rprof("test.out") > data.frame("a") X.a. 1 a > Rprof(NULL) So far, so good. Next, I define myClass. > setClass("myClass", representation(mySlot = "numeric")) [1]

Hi Consider the following example: f <- function(expr) g(expr) g <- function(expr) { ? h(expr) } h <- function(expr) { ? expr # evaluation happens here ? i(expr) } i <- function(expr) { ? expr # already evaluated, no costs here ? invisible() } rprof <- tempfile() Rprof(rprof) f(replicate(1e2, sample.int(1e4))) Rprof(NULL) cat(readLines(rprof), sep = "\n") #>

I am having some difficulties using dynamically loaded C functions on a Sparc 10 with R compiled using cc (both R-0.49 and R-0.50). I get sporadic errors with the error message: Error: character variables must be duplicated in .C/.Fortran, with C functions which pass character variables. my C functions look like: anyfunc(char **filename, other variables ) This error message appears about 25%

Full_Name: Jelle Goeman Version: 1.9.0 OS: mingw32, windows 2000 Submission from: (NULL) (145.88.209.33) Hi Everyone, I get very strange results using the function hasArg with the ... function argument. In my own function: > gt <- globaltest(X,Y) > sampling(gt) works fine, but > sampling(globaltest(X,Y)) results in: Error in eval(expr, envir, enclos) : "missing"

Hi, I'm using xapian with c# and mono and i'm having a segfault in get_weight. When i print the index variable, the value is clearly too high. I think something write over it. Do you have any idea on how i could trace the beginning of the segmentation fault ? Thanks, -- Yann

I have an object with an attribute "tframe" for which there is a generic method print.tframe and also a method print.tframe.default defined in a library. However, when I use attributes(object) I get the message $tframe Error: couldn't find function "print.tframe" It's as if <primitive: attributes> is not looking through the search list? Any suggestions?

Would you consider the following patch to eval.c to allow compatibility with RCC?

Hello everybody, i am a newbie in using Xen. The first three tries to install Xen on my Gentoo box aren''t very successfull. But now i know how to get the dom0 Domain running. So my Xentoo (Xen + Gentoo = Xentoo) ist coming up. My system is configures like this: /dev/hda1 = /boot /dev/hda2 = / /dev/hda3 = LVM-Partition /dev/hda4 = SWAP /dev/vg01/SYSP = Gentoo System for dom1

Hi, I'm trying to replace function call with call to wrapper(function_name, num_args, ...), where varargs hold args of original call.

Dear useRs, Some time ago I queried the list as to an efficient way of building a function which acts as ls() but with a different default for all.names: http://tolstoy.newcastle.edu.au/R/e6/help/09/03/7588.html I have struck upon a solution which so far has performed admirably. In particular, it uses ls() and not its explicit source code, so only has a dependency on its name and the name of

Hi Dimitry, This makes sense if you think about it from the perspective that the string you want passing must be passed at runtime, and so can't use a const char * from compile time. You need to make the string visible in the compiled image, and use that as the argument. A string is an array of 8-bit integers, so you need to create a ConstantArray. Value *v = ConstantArray::get(Context,

Optimizer doesn't know how to calculate the object size when it finds condition that cannot be eliminated. There is example: ----------------------------------------------- #include<stdlib.h> #define STATIC_BUF_SIZE 10 #define LARGER_BUF_SIZE 30 size_t foo(int flag) { char *cptr; char chararray[LARGER_BUF_SIZE]; char chararray2[STATIC_BUF_SIZE]; if(flag) cptr =

Hello, I added the support for netgroups to be used in the AllowUsers and DenyUsers parameters. This has some advantages: * hostnames or ip addresses need not to be written or maintained in the sshd_config file, but can be kept abstract names what also simplifies a bit largescale openssh installations * sshd_config needs not change and sshd be restarted when changing the list of allowed /

S Programming by Venables and Ripley (page 78) has the example listed at the end of this email. However, I get the following error when I try the example. I don't understand the descriptions of NextMethod on its help page. Could somebody let me know how to fix the error of this example? > test(x) c1 c2 Error in NextMethod() : no method to invoke Calls: test -> test.c1 -> NextMethod
