Hi everyone, I'm very new to R and I like to learn a lot... actually I have a little problem concerning errorbars with xyplot.

If one makes the reasonable assumption that Pct is much larger than Cutoff, sorting Cutoff is the expensive part e.g O(nlog2(n) for Quicksort (n = length Cutoff). I believe looping is O(n^2). Jeff's approach using findInterval may be faster. Of course implementation details matter. -- Bert On Mon, Oct 16, 2023 at 4:41?AM Leonard Mada <leo.mada at syonic.eu> wrote: > > Dear

As part of checking Martin Maechler's observations of sorting efficiency I have been putting the code under the microscope. Part of this involved comparing the performance with Splus. I turns out that the R code is much slower. A good deal of this is due to the interpreted front end to the R verion of sort. It is worth taking a look at the sort function and seeing if you can see what the

Hello. I'm using these commands to compile the code below in order to collect edge/blocks profiling: clang -emit-llvm -c sort.c -o sort.bc opt -insert-edge-profiling sort.bc -o sort_prof.bc clang sort_prof.bc -lprofile_rt -L/llvms/lib -o sort_prof then I run the program and display the profiling information using llvm-prof sort_prof.bc, and the result is:

Motivated by Deepayan's recent inquiries about the efficiency of the R 'quantile' function: http://tolstoy.newcastle.edu.au/R/devel/05/11/3305.html http://tolstoy.newcastle.edu.au/R/devel/06/03/4358.html I decided to try to revive an old project to implement a version of the Floyd and Rivest (1975) algorithm for finding quantiles with O(n) comparisons.

I am using SWord from statconn: http://rcom.univie.ac.at/download.html It allows you to put r-commands into Word (similar to odfWeave). Output is directed to Word including figures and tables.

Hi, I thought about changing the RPM package the guys of Redhat created, because I wanted an Init Script for SLES10 built-in. I started documenting the steps I took. Maybe it''s useful for someone else, although in German.. but the basic steps should be useable. My little Installating puppet Howto: http://wiki.njh.eu/Konfigurationsmanagement#Installation_3 The Init Script for SLES10:

Everyone, There is non-determinism in LLVM codegen in the following scenarios: 1. Between back-to-back runs of the same LLVM toolchain 2. Between Release vs Release+Asserts toolchains 3. Between Linux vs Windows toolchains The main reasons for the non-determinism in codegen are: 1. Iteration of unordered containers (like SmallPtrSet, DenseMap, etc) where the iteration order is undefined 2.

Hi, When I create an environment object with new.env() and populate it with values then how can I save it into an .RData file properly, so it can be loaded later on in a new session? Saving an environment object with save() or save.image() results in an error message when loading again: Error: protect(): protection stack overflow Regards, benjamin ======================================

Hi Anne, I would suggest to change the linear model to lm(BloodPressure~Age), as this model makes more sense in biological means (you would assume that age influences pressure, not vice versa) and also obeys the statistical assumption of weak exogeneity, that age can be measured without error, at least compared to error-prone bp measures.

Everyone, The following patch to reverse iterate SmallPtrSet's has now been merged: https://reviews.llvm.org/D26718 This is how LLVM behavior will change due to this patch: - In LLVM builds with *assertions enabled*, SmallPtrSet's would always be reverse iterated by default. This default behavior can be overridden via the flag "-mllvm -reverse-iterate=<true/false>".
