similar to: write.table with row.names=FALSE unnecessarily slow?

Looks like I?m bumping a lot into unexpected behaviour lately, but I think I found a bug again, but don?t have access to Bugzilla: Write.table (from core-package utils) doesn?t handle nested data.frames well, the quote arguments only marks top-level character (or-factor columns) for quoting, so this fails: df <- data.frame(a='One;Two;Three',

Hi, I have two variables ranging both from 0 to 1 (n=500 each). Now I am interested in plotting them both in one plot (using ggplot2). So far I used ecdf() (from an example I found with google) to get values for the cumulatice distribution function which gives a relative curve. I also want to do the same plot but using absolute cumulative values instead of relative. Can that be done with ecdf or

Dear all, I have invested substantial amount of work in a complicated, yet on screen perfect looking graph that uses image(). Unfortunately saving it as pdf (or quartz.save at high resolution) all generate very disturbing border lines around each small rectangle that image() has drawn. While using Preview it helps to turn off antialiasing to make those faint lines disappear on screen

HI all, A patch of mine from a few weeks ago made String#mb_chars use a proxy class for 1.9.x as well as 1.8. This proxy overrode some methods that were buggy in 1.9.1. but that work in 1.9.2. Since Rails officially now only supports 1.8.7 and 1.9.2, these methods should definitely no longer be overridden. Here''s the LH ticket:

I'm embedding flac in a Samba VFS application. flac gets called to decompress files, which Samba serves up to the client as WAV files. Every time a Windows client browses a folder, it opens music files to read the header, and then it closes them without reading the entire file. I'm accessing flac via popen/pclose. Each time I close the pipe to flac 'prematurely' (i.e.

Dear R-devels, timedatectl binary used by Sys.timezone does not always work reliably. If it doesn't the warning is raised, unnecessarily because later on Sys.timezone gets timezone successfully from /etc/timezone. This obviously might not be true for different linux OSes, but it solves the issue for simple dockerized Ubuntu 16.04. Current behavior R Under development (unstable) (2018-05-04

Hello, There is a small but annoying problem with linking libwrap in openssh. The library is added to LIBS which makes it be linked in to all binaries. This is unnecessary and leads to bogus dependencies if libwrap is a shared library. Following is a trivial fix that reserves a separate autoconf substitution variable LIBWRAP, which is only used for sshd. Please apply. Maciej -- +

I have just upgraded my Debian Buster (Dovecot 2.3.4, I think it was) to Bullseye (Dovecot 2.3.13). The Dovecot server works fine, which of course is the really important thing. But I have a cron job that cleans up all old mail from the mailbox that I use for my mobile phone by running "doveadm expunge" every night. That worked fine in 2.3.4, but now it fails: > jdmobile at

Dear Rdevelopers The background for this email is that I was helping a PhD student to improve the speed of her R code. I suggested to replace calls like t(AA)%*% BB by crossprod(AA,BB) since I expected this to be faster. The surprising result to me was that this change actually made her code slower. > ## Examples : > > AA <- matrix(rnorm(3000*1000),3000,1000) > BB <-

Hello, The problem I'm working now requires to operate on big matrices. I've noticed that there are some packages that allows to run some commands in parallel. I've tried snow and NetWorkSpaces, without much success (they are far more slower that the normal functions) My problem is very simple, it doesn't require any communication between parallel tasks; only that it divides

Right now we emit on every kick, but this is only necessary if something will ever be able to observe that the fence completed. If there are no refs, leave the fence alone and emit it another day. This also happens to work around an issue for the kick handler -- a kick can be a result of e.g. nouveau_bo_wait or explicit kick, or it can be due to lack of space in the pushbuf. We want the emit to

Hi, I have a 5x731 array A, and I want to compute the sums of the columns. Currently I do: apply(A, 2, sum) But it turns out, this is slow: 70% of my CPU time is spent here, even though there are many complicated steps in my computation. Is there a faster way? Thanks, Martin
