I have a data set in the format below. I would like to perform a factor analysis on BM1-BM20 as they are 20 biomechanical measurements of the trial (hitting a baseball). However, my observations are not independent and, I assume, I have to account for this. I have consulted the R literature via RSeek and Google (and I have consulted some very knowledgeable colleagues) and cannot find any method of doing this in R. Is...

Is there any known problem with accountsservice-0.6.35-12 with NFS users? After logging in via lightdm they are not "remembered" and there is no entry created to /var/lib/AccountsService/users Downgrading to accountsservice-0.6.35-9 resolved that issue Gerhard Schneider -- Gerhard Schneider Institute of Lightweight Design and e-Mail: gs at ilsb.tuwien.ac.at Structural

Many people seem to wait for the announcement of CentOS 6.0, so I want to share some test results I did with SL 6.0.. The actual 6.0 kernel can NOT allocate tape buffers when the server is heavily loaded at least on some LSILogic hardware. There is a big problem of slab buffer increase that can cause reboot/freeze of the server under load. Reported by many and verified by me :-( So perhaps

Dear Subscribers, I am using R for quite a while nowadays on Ubuntu 10.04 LTS. I a using R for doing my statistics. Furthermore I am using it as a tool to generate the graphics for my publications. I am currently working on a project which involves nls-fits of three dimensional surfaces such as ellipsoids or even more complex. I have been searching R help and the manuals for a possibility to

An user is using 2 displays and configured Gnome to "Static Workspaces only on primary display on" using gnome-tweak-tool Till 7.2 it was working as expected. After upgrading to 7.3 the content on the primary screen gets mirrored to all workspaces. When switching to "Static Workspaces only on primary display off" everything is working as expected on 7.3, too. Any ideas?

After upgrading approx. 50 machines to 7.4 we discovered a reproducible SegFault of one of our commercial programs we use. This SegFault does not occur on CentOS 7.3 and it occurs only on Xeon E3-1230 V3, Xeon E5-2690 and Xeon E5-2697 v2. It does NOT occur on Xeon E5-2697 v3 and Xeon E3-1231 v3, AMD Ryzen and older Core I7-9xx. It is not dependent of the kernel, we switched back to an CentOS

Today we tried to update machines w/ Core2 Duo E6750 from 3.10.0-693.11.1.el7.centos.plus to 3.10.0-693.11.6.el7.centos.plus and the machines did not boot due to a kernel panic. Before we dig any further I wanted to know if the 11.6 kernel has been tested on old hardware, too, or if the problem is well known but not documented (yet). Thank you in advance!

The upstream provider decided to remove OpenGPG support in its thunderbird-78 packages, see https://bugzilla.redhat.com/show_bug.cgi?id=1886962 https://bugzilla.redhat.com/show_bug.cgi?id=1886958 https://bugzilla.redhat.com/show_bug.cgi?id=1837512 recommending to either use Mozilla binaries, use Flatpak or switch to Evolution Is there any plan to provide thunderbird-78-full packages in e.g.

Dear everyone I tried reading my own Excel spreadsheet data in R, but kept getting an warning message 'incomplete final line by readTableHeader'F:\mm1data.xls'. On viewing its rows and columns, only 'NA's were returned. Having difficult time with this problem for too long, any solution would be greatly appreciated. Thank you in advance Dai Nishikawa (PhD candidate)

Do CentOS 5.4 users still have to use the RedHat preliminary kernels (http://people.redhat.com/jlayton/) for getting a NFSv4 safe kernel or have the patches been incorporated into CentosPlus kernels? Or is kernel-2.6.18-164.3.1.el5 somewhere in the queue? Thanks in advance! GS -- Gerhard Schneider Institute of Lightweight Design and e-Mail: gs at ilsb.tuwien.ac.at Structural

Are there any 64bit CentOS5 kernels available that are immune against the exploit mentioned in the subject? Turning off 32bit support is no option to me.. Gerhard Schneider P.S.: Source code can be found at http://seclists.org/fulldisclosure/2010/Sep/268 and is working "well" on 2.6.18-194.11.3.el5.centos.plus -- Gerhard Schneider Institute of Lightweight Design and e-Mail: gs

Are there any known race conditions with 2.6.18-194.26.1.el5 x86_64 and NFS4? Today a user managed to shut down two identical Intel servers by copying a simple text file via NFS4. Reverting back to 17.1 made the error disappear. On other non-identical hardware the error was not reproducible (so it must be a combination of hardware and this special kernel revision). Anybody interested in a

After a crash I tried wget http://debuginfo.centos.org/5/x86_64/kernel-debuginfo-2.6.18-194.32.1.el5.x86_64.rpm as usual. But for 32.1 there is no kernel-debuginfo. Is there any reason for that?

Hi All, I have a WD RE4-GP which dropped an Adaptec 51645 RAID controller. I ran a smartctl short test on the drive and it failed with a read error. So I ran the Western Digital's own diagnostic software (DLGDIAG), both the short and extended test on the drive and it passed with no errors. So I ran the smartctl short test again and again it failed. I then ran smartctl long test and that

Hello all, In the process of building a new VM box to replace several individual CentOS servers, I've had the "interesting" experience of running both CentOS-5.5 and RHEL-6 (eval copy) as I build out the hardware based on a Supermicro motherboard. A couple of observations regarding RAID-6: - RAID-6 arrays created on RHEL-6 don't seem backward compatible with CentOS-5.5.

Hi All, I have a question which does not pertain directly to the use of R but comes from my use of R! I have data which can be described as 3-dimensional e.g. (x,y,z), with no negative component. The suggested way to analyze this data is via multivariate techniques or by calculating what amounts to a levene's test on the data and then an ANOVA on the three components if the first test is
