Software :: Where To Find Guide For Reading ANOVA Output
Aug 18, 2010
Where can I find document re "how to read anova output"? Google found many of them. But seemingly non of them can explain to me following output:-
> tabA = c(5.67, 5.67, 5.55, 5.57)
> tabB = c(5.75, 5.47, 5.43, 5.45)
> tabC = c(4.74, 4.45, 4.65, 4.94)
> tabs = data.frame(tabA, tabB, tabC)
> tablets = stack(tabs)
> anova(lm(values ~ ind, data = tablets))
Code:

I wish to know what could be the possible cases for this error:cp: reading `filename': Input/output errorI am getting this message when I am trying to copy a big file of around 50MB.
I have a 7.2 GB file (VMWare virtual machine file) that I am trying to copy from its original location to the another folder OR to external hard drive...each time I try to do this, I always get the following error after the copying process reach 'exactly' 1.4 GB
Error reading from file input/output error
And I have to either Cancel or Skip
I've tried to split the files to smaller pieces but the idea didn't work as I still get the same error whenever I try to compress/ split or do any operation with this file. how I can copy this file?
I have mounted an NFS share with ISO images on my kvm Server. If i connect such a iso to a VM (using virt-manager) for installing a operating system i get the following error on startup: Error starting domain: internal error Process exited while reading console log output: char device redirected to /dev/pts/1 qemu: could not open disk image /mnt/iso/public/Linux/Distributions/Debian/debian-504-amd64-netinst.iso: Permission denied
The problem is definitly that kvm (or qemu or libvirt-bin, i don't know) tries to set permissions (rwx owner for libvirt-qemu, --- for kvm group, --- for other) on the file, although it has read permissions. Is it possible to change this behavior?
I'm still trying to find out if my coby mp3 player will actually play mtv video files as is advertised.
ffmpeg -formats does list mtv but the only command I really ever used was one to convert a vid to an mp3 so I tried Code: ffmpeg -i test.mp4 -acodec copy output.mtv it returns Code: Unable to find a suitable output format for 'output.mtv' I can't find any mtv files online for purchase or free for that matter, so I know this is all pretty obscure but shouldn't there be a way to convert them since ffmpeg lists mtv format?
I don't understand the results of a simple performance test I ran using two basic scripts (running on a high end server):
perfVar.zsh :
#!/bin/zsh -f MYVAR=`cat $1` for i in {1..10}
[code]...
Performance test result:
> time ./perfVar.zsh BigTextFile > /dev/null ./perfVar.zsh FE > /dev/null 6.86s user 0.32s system 100% cpu 7.177 total > time ./perfCat.zsh BigTextFile > /dev/null ./perfCat.zsh FE > /dev/null 0.01s user 0.10s system 91% cpu 0.118 total
I would have thought that accessing a VARIABLE was way faster than reading a FILE on the file system... Why this result ?Is there a way to optimize the perfCat.zsh script by reducing the number of accesses to the file system ?
i installed kernel 2.6.34 to fix my lid closing issue, and that went great. but now when i go to reinstall my broadcom i get this error. Code: Reading package lists...

I'm testing some multi-plat java code and I'm getting a bit frustrated with the Linux tests. I need to run the command: Code: $ java -jar /home/developer/TCO/TabletComicOptimizer.jar <file> <args[]> against all the files that match a specific criteria. I've tried various find syntax and I can't seem to get it right.
Normally I would just create a bash script and populate the results of find into an array and then just enumerate the collection but in this specific case I want to demonstrate this operation at the bash terminal.
I've tried things like: Code: ~/TCO $ find . -type f -iname "*.cb[rz]" | xargs java -jar TabletComicOptimizer.jar {} 1200x1800 ; Thinking that the {} is the substitution for each file returned by find but it's not working. How do I execute my java program against each result in the find operation?
I'm wondering where I can find description of mpstat output?.. I'm talking about the output of all available counters presented by mpstat. For instance:
I'm trying to pull out sections from a bunch of files. For one file, I use:
Code: sed '/string1/,/string2/ !d' <filename.ext >newfilename.ext to pull out everything between two strings in the original file and put them in a new file.
I am trying to automate an svnadmin dump command for a backup script, and I want to do something like this:
find /var/svn/* ( ! -name dir -prune ) -type d -exec svnadmin dump {} > {}.svn ;
This seems to work, in that it looks through each svn repository in /var/svn, and runs svnadmin dump on it.
However, the second {} in the exec command doesn't get substituted for the name of the directory being processed. It basically just results a single file named {}.svn.
I suspect that this is because the shell interprets > to end the find command, and it tries redirecting stdout from that command to the file named {}.svn.
I have some big files of logs that contain errors printed by an app. They are most of the time relevant, however most of them are similar. So i figured i could check what happened between a time interval with a find.
Im using this one
Code:
And I get an output similar to this one.
Code:
Is there a way to condensate the output lines to get only one or two, indicating the start and last occurrence of a block? Or I need to create a program to do so?
Because right now I get thousands of similar lines, but when I'm scrolling through them i sometimes miss relevant information that i would've otherwise noted if it wasn't all that spammy.
I had followed this Guide to get proftpd with mysql on a Ubuntu server edition the last one available to download 10.04.1I did everything. phpmyadmin is working I can access it via the browser and create users and groups.When I am trying to enter my server using the ip or the domain name I am getting an instant error.Flash fxp's error log
Code: [R] Connecting to 192.168.25.117 -> IP=192.168.25.117 PORT=21 (attempt # 2) [R] Connected to 192.168.25.117
I haven't used slackware for many years. There used to be a sticky thread with a great kernel compiling guide for slackware. It feels somewhat unnatural to me to use slackware without a shiny new kernel. Does that guide still exist? I'm working from memory right now.
We make everyday a DB Mysql backup on Linux redhat Enterprise. We are using a bash shell script (and putting it in the crontab) to execute it automatically everyday. We added a line to this script telling, once the backup has completed, to find old backup files (stored on hard disk after each backup) older than x days to remove them. We use the find command (search for file type) with the mtime option and in combination with rm command. Everything runs ok but we also want to add some new code to the same line: If find command cannot find anything or fails, for example if it cannot delete file or fails, send the error message (standard error output) to an error file (like error000001 and increasing) and mail the errorxxxx file to an email address for example to admin@companyname.com. What would be the code for this issue to add it to our find command in the same bash shell script??
I just installed apt-doc package. My question is how do I read the User Guide in this package ? In general how do I use the items from a package once I install it ?
Anyone can show/tell or direct me to a guide to removing Windows 7 off my other partition? I'd just prefer to have Ubuntu 10.4 on the entire HD instead of dual booting. I came here so I didn't have to reinstall and wipe the entire HD to do so. Pretty sure there's a way to wipe 7 off the other side and update GRUB to only detect ubuntu.
I need to set up a named server for a class room with 10 imaginary hosts the sub domain managed by this name server is s123456.eca.edu.au where 123456 is to be replaced by your student id. The named server will forward unresolved queries to the dns server. It will be on Ubuntu.
I am not averse to using the command line it's just that I don't know many commands so I need complete instructions when using the command line. I need to set up Ubuntu server at the office and I'm the dangerous IT guy that just knows enough to be dangerous but the little company won't hire a real IT guy so I do IT besides my real job, which is to usethe computers, not fix them, set them up, configure networks, servers etc.
