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:

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'm having difficulty with Rprof. I have a documentation example test.qss that runs fine without profiling, but under Rprof, > Rprof() > source("test.qss") Error in standardGeneric("model.matrix") : UseMethod used in an inappropriate fashion Luke wrote about a similar circumstance last summer: # From: Luke Tierney (luke@stat.umn.edu) # Date: Fri Jul

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

From: Gene Cumm <gene.cumm at gmail.com> CORE/cache: add cache priority parameter; Passing in DX=0 forces the cache entry to stay at the least recently used spot. Any other value allows it to continue on previous behavior of most recently used position in the list. Change ldlinux.asm and extlinux.asm (the only 2 users of cache) to pass in DX=1. Push/Pop DX unless it's definitely safe

Greetings all, Recently ran into a seg fault the keeps reoccurring whenever R-java is used (I believe). Not sure if this is an R issue or an openjdk issue so I'm trying to cover all bases with this report. I tried downgrading R version from 3.4.0 to 3.3.3 with the same results. Also tried downgrading java version from 1.8 to 1.7 with no luck. Running on a fully updated CentOS 7 x86_64,

The Rprofmem facility is currently enabled only if the configuration option --enable-memory-profiling is used. However, the overhead of having it enabled is negligible when profiling is not actually being done, and can easily be made even smaller. So I think it ought to be enabled all the time. I've attached a patch doing this, which also makes a number of other improvements to Rprofmem,

I made a mistake here, I get zero same as you. I want to fix it to get correct value. On 16.03.2016. 19:28, Duncan P. N.

There is example:

This is about 90% of the core work. I omited a few files from the patch set since they are basicly small blocks of #ifndef HAVE_NEXT/#endif to get it to compile. Daimen, feel free to let me know what you applied and what your rejecting and why.. so I can work on cleaning things up. Andre, Only thing of note you may want to look into is NeXT does not use "ut_user" in it's lastlog.

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 =

Hi, Am am plotting aggregated frequency data (extracted from an RDBMS) relating to DNA sequence features for each of the human chromosomes as described in the table chromosomes below (the frequency data is in a table 'hits' that has a value (or not) for each of a set of bins across each chromosome). I would like to mark the extent of the chromosome (according to the length value in

Hi all. I would like to use the rbga.bin function (from the "genalg" package) as part of a model selection process to whittle down a list of ~40 potential explanatory variables to only the most important ones. Unfortunately, despite my working knowledge of R for linear modeling and basic statistics, I cannot understand the two examples provided with the documentation for rbga.bin

Dear all, at the following address http://linaria.dst.unive.it/~claudio/R/Rmaterial.html#ga you can download a package to build simple genetic algorithms. I wrote this package to introduce genetic algorithms to student in labs, which means, the package emphasize "how a ga works" instead of "how fast it could be". Please, let me know any comments or suggestions, Bests,
