Hi R-Helpers, Sorry to bother you, but I have a simple task that I can't figure out how to do. For example, I have some names in two columns NamesWide<-data.frame(Name1=c("Tom","Dick"),Name2=c("Larry","Curly")) and I simply want to get a single column

Hi, You were on the right track using stack(), but you just pass the entire data frame as a single object, not the separate columns: > stack(NamesWide) ? values ? ind 1 ? ?Tom Name1 2 ? Dick Name1 3 ?Larry Name2 4 ?Curly Name2 Note that stack also returns the index (second column of 'ind' values), which tells you which column in the source data frame the stacked values originated

Just to repeat: you have NamesWide<-data.frame(Name1=c("Tom","Dick"),Name2=c("Larry","Curly")) and you want NamesLong<-data.frame(Names=c("Tom","Dick","Larry","Curly")) There must be something I am missing, because NamesLong <- data.frame(Names = c(NamesWide$Name1, NamesWide$Name2)) appears to

I may be missing something but using the plain old c() combine function seems to work fine: df <- data.frame(left = 1:5, right = 6:10) df.combined <- data.frame(comb = c(df$left, df$right)) df left right 1 1 6 2 2 7 3 3 8 4 4 9 5 5 10 df.combined comb 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 -----Original

I just put a USB hard drive into service, but find that unless the drive is connected to my PC the machine won't boot and drops to a shell. Below is the line I added to fstab. I thought that the option "noauto" would prevent the machine from trying to mount the drive /dev/sdb /usbdrive ext3 user,noauto,rw 0 2 What am I doing wrong? Any advice is

...not just a problem of -partial or something similar. Ok, I haven't tried it without ssh yet, but it really looks very strange. The version is the rsync 2.5.6cvs version from debian-unstable.

Hi everybody I am trying to get RoR to work with lighttpd. Nearly there, but I am stuck with a strange phenomenon. If I configure lighttpd to serve pages on say port 2000, I can get at my testapp fine and see the "Welcome aboard" page. However, if I configure lighttpd to use port 80, I get a download prompt from my browser. If I access my URI like

Apologies for the novice question, but this is likely beyond my google searching range.. I am trying to create a table from the summaries of a file. The 2 column data table looks like; Harry 335/335 Harry 124/506 Harry 124/506 Dick 133 Tom 335/335 Tom 335/335 with 1000 unique values in col 1, 300 unique in col 2. The 'summary' doesn't seem

I'm looking into backing up my CentOS 5.5 system using an external USB 2.0 hard drive. Anyone with experience with Toshiba Canvio USB 750 GB unit? I'm backing up to DVDs now and would like to streamline the process. Any advice is welcome with thanks. Dick -- Yes indeed...the Hokey Pokey *is* what its all about!

scrub completed after 1h9m with 0 errors on Tue Feb 17 12:09:31 2009 This is about twice as slow as the same srub on a solaris 10 box with a mirrored zfs root pool. Has scrub become that much slower?

Good Morning-- I'm looking to shore up security in my system and with communications. Can you point me to the proper version of GnuPG for CentOS 5.3 (Final)?

I have Centos 7 installed on my laptop which works perfectly fine. I use a variety of music apps including VLS, mplayer and squeezelite. They all work fine, and using the KDE mixer app I have the levels set just as I like them. Why is it then that if i start up either Firefox or Chrome, whichever I start up first creates a new sound device which appears in the mixer, and then changes my

After a liveupgrade and luactivate I can login to the -new- BE. My question is: do I have to luactive the -old- BE again if I want to chose that one from the grub menu or can I just run it if I want to. -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + http://nagual.nl/ | SunOS sxce snv107 ++ + All that''s really worth doing is what we do for others (Lewis Carrol)

I'm using Simplecast to feed 8 mount points of a 24/7 live stream to Icecast on a win platform. When I have the Statistics Relays graphing activated, I get an entry each minute in Access.log for each of the mount points. That particular entry is pretty much useless but of course, being able to see the IP address of client drops can be useful. This log grows to mammoth proportions unless I

Greetings I'm new to the forum but have been streaming successfully with SimpleCast/IceCast2 for about 8 months. Both Simplecast and IceCast2 are running on the same Win2K system. Now I want to do something that has me stumped. It really is a two pronged problem. Here's the setup: Icecast is encoding the same live audio to multiple mount points, allowing me to easily track the

Hello- I would like to remove the columns of a matrix that contain all zeros. For example, from x<-matrix(c(1,5,3,2,1,4,0,0,0), ncol=3,nrow=3) I would like to remove the third column. However, because this is in a loop I need a way to first determine which columns are all zeros, and only then remove them. I.e., I don't know which column of x contains all zeros until after x is

FULL backup to a file zfs snapshot -r rpool at 0908 zfs send -Rv rpool at 0908 > /net/remote/rpool/snaps/rpool.0908 INCREMENTAL backup to a file zfs snapshot -i rpool at 0908 rpool at 090822 zfs send -Rv rpool at 090822 > /net/remote/rpool/snaps/rpool.090822 As I understand the latter gives a file with changes between 0908 and 090822. Is this correct? How do I restore those files? I know

The attached patch makes two changes to the behavior of the -v option: 1) The initial "building file list ... done" and the last two lines with transfer statistics are moved to verbose level 2, which means that you have to specify -vv to see them. When I use -v, I only want to see which files are being updated. Perhaps the statistics could be controlled by a separate option,
