I have a several character variables that I need to recode, but some of them have special characters like single quote or ( ). How tell R to ignore these special characters so I can rename them? Below is the error message I am getting. social$FamilySupport[social$FamilySupport=="Mr. XXXs' extended family live in the Nashville area where he and his wife reside."]<-"Highly

Hello developers, I have a question about supported bitrates for SPEEX. Regardless of whether I specify a 10kbps or a 8kbps bitrate, the encoded .spx file is the same size and have the same PESQ value. This makes me wonder if SPEEX supports arbitrary bitrates, or only a certain set. A few more details about my configuration: I am using SPEEX encoder version 1.1.12 I am encoding a narrowband

I have a variable that identifies citizen type but some of my rows are blank. I want to replace the blank entries with the correct value which is conditional on another variable. In SAS, my conditional statement would be as follow: if citizenType="" and primarylanguage="English" then citizenType ="US citizen"; else citizenType=citizenType; When I try to duplicate this

I am new to R, and I need to do some simple data cleaning. In the example below I have 164 rows of data with a missing value. I want to convert these missing to unknown while keeping the other values as is. summary(ABIClinical$HasSkinBreakdown) no unknown yes 164 914 163 178 When I did the following code:

I am trying to create the roc plot bootstrap method from library(verification), and when I set the plot =both or emp then I get the following error. The roc.plot works fine when the plot is set to binorm. This is my first time using this function in R and am not sure what this error means or how to resolve the issue. It seems to work ok with the example dataset. Is there an option or data

i am currently using roundcube my webmail and configure using dovecot quota plugins. but it seems to not be updating the maildirsize when new mails comes.Deleting the maildirsize will recreate the files correctly.Is there any solutions to this problem with dovecot. Either you're not using dovecot-lda to deliver the mails, or you haven't configured quota plugin correctly for it.

I just remembered an anomalous result that I stumbled upon whilst tweaking the command-line options to llvm-gcc. Specifically, the -msse3 flag does a great job improving the performance of floating point intensive code on the SciMark2 benchmark but it also degrades the performance of the int-intensive Monte Carlo part of the test: $ llvm-gcc -Wall -lm -O3 *.c -o scimark2 $ ./scimark2 Using

Hi Peter, > Why not do this too? I've applied this - thanks for the patch! Ciao, Duncan.

Duncan, Do a quick check here on x86_64-apple-darwin10 with svn llvm and svn dragon-egg against release gcc 4.5.0, the results from the himenoBMTxpa benchmark compiled at -O3 look pretty good. With stock gcc-4.5.0, we get... Grid-size = M mimax = 128 mjmax = 128 mkmax = 256 imax = 127 jmax = 127 kmax =255 Start rehearsal measurement process. Measure the performance in 3 times. MFLOPS:

I finally got around to testing this on a Bloomfield processor (Early 2009 MacPro 2x2.66 GHz dual-quad core) and the regressions from http://llvm.org/bugs/show_bug.cgi?id=22589 are even more severe. For 10 runs of scimark2_1c built with "-O3 -march=native"... llvm 3.5.1 1204.16+/-2.66 Mflops 3.6 branch 866.49+/-1.26 Mflops Do you seriously want to ship with a 39% performance

Hello, I was wondering if anyone has had success at running the LLVM within the windows xp kernel? The XP kernel really does not like C++ or exceptions and there is a project which attempts at getting C++ in there. In your humble opinion, do you think it can be done? My project is a reconfigurable device driver system which dynamically optimizes for the available hardware. two thirds is within

Hi I just started to use rsync & samba to backup some windows NT & 98 shared directories to a linux machine linux: debian 2.2.4 rsync: 2.2.5 samba: 2.2.3a-6 I first mount the windows directory on the linux and then do a local rsync. ---command on linux umount /data/transfer mount -t smbfs -o username=user,password=passwd //ntserver/exp_dir /data/transfer cd /data/transfer rsync -a

I have at home two centos boxes: Box A - centos 6.4. gui version Box B - centos 7.1. minimal version. They are connected to 100Mb router (both boxes have 100Mb network adapters). Box B has software raid 1 and sata II interfaces.?On box B samba4 is installed and I copy files to samba share ( from box A to box B). Network monitor (iptraf-ng) shows only 20000 kbps of this copying operation. That is

I have been working with SYSLINUX/PXELINUX Mostly v.2.x recently v3.0 &v3.1 to remote-boot IBM PC's off of 1.44Floppy Images with great success. I have searched through several distributions and the SYSLINUX package seems to be by far the easiest to work with.. (thanks) My question would be: Is it possible to boot a diskless client PC with Complete hard disk images? or even better hard

With a 100Mbit connection it wouldn't be possible to reach transfer rates of 110MB/Sec. A realistic good transfer rate for a 100Mbit connection is just around 11 MB/Sec. Regards, Marc
