For example, subtracting 1:2 from the rows of a two-column matrix: > t(apply(matrix(1:6,ncol=2),MARGIN=1,function(y) y - 1:2)) [,1] [,2] [1,] 0 2 [2,] 1 3 [3,] 2 4 > sweep(matrix(1:6,ncol=2),MARGIN=2,1:2,FUN="-") [,1] [,2] [1,] 0 2 [2,] 1 3 [3,] 2 4 Is there a logic to this difference, or is it just a quirk of the history of these

Hello, While reading Dan North''s BDD tutorial <http://dannorth.net/introducing-bdd>, I tried to implement his ATM example as spec stubs. When I first implemented it creating a context for each of his scenarios, I noticed that there is duplication and a combinatorial explosion of the specs. I attached the full files to this email. For brevity, I will use scenario 1 in the body of

Self-explanatory, I hope (note the period on the end of the username); sieve/pigeonhole does not allow you to have senders which end with a period, which means that any UNIX users with such usernames who send mail have it rejected by sieve: # useradd testuser. # su - testuser. $ mail david at example.com -s 'testing' 123 .

I'm able to do this as follows, but am wondering if anyone knows a simpler way which still avoids explicit loops? > (mystring <- letters[1:5]) [1] "a" "b" "c" "d" "e" > unlist(sapply(mystring[-length(mystring)], + function(x) paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep=""))) a1 a2 a3

Small suggestion for the documentation: Should the = operator for assignments, described on http://developer.r-project.org/equalAssign.html, now be included in the operator table in doc/manual/R-lang.texi? If so, one possibility could be after lines 1096/7: @item @code{<-} @tab Left assignment, binary @item @code{=} @tab Left assignment, binary Also, where is the best place to send

How can I look up the aspect ratio of a plot, so I can use that to correctly adjust the angle of text which is supposed to be parallel to a line in the plot? The following example code works for a 1:1 aspect ratio, but puts the text at the wrong angle if the plot region is short and wide or tall and narrow. I can't find a par() component containing the plot aspect ratio. It will be for

Hello, I was planning to use the output of asterisk -rx "show queues" in a script when I noticed that sometimes asterisk only outputs the first line of the response. e.g: debian:/# asterisk -rx "zap show channels" Chan Extension Context Language MusicOnHold debian:/# asterisk -rx "zap show channels" Chan Extension Context Language

I'd like to use native moh instead of with mpg123... for some reason the processes never bloody die. For native moh to not spawn an external player, I'd need to convert the default supplied moh sound files in /var/lib/asterisk/mohmp3 to ulaw and g729 format. Anyone know of a free, easy way to convert them? Thanks, Doug.

Aloha all, I love using ggplot. It took a while to get used to the grammar of graphics, but it is starting to get easy now that I am thinking in a more structured way. A question. I'm making a wind rose that I'd like to be oriented with due north straight up. I've discovered that the orientation is sensitive to how north is represented. When north is represented as 0,

Hi There is a Centos 7 up-to-date box with 2 interfaces, let's say 192.168.1.12 - enp2s0, 192.168.1.13 on enp3s0. Default gateway on enp2s0. The gateway is pfsense, IP is 192.168.1.1 with 2 WAN connections On the gateway the outgoing traffic is routed by source ip to different WAN, 192.168.1.12 to WAN1 and 192.168.1.13 to WAN2 On the centos box are set all the route and routing rules:

Does everyone have two processes running for mpg123? I always have them when I'm running an idle Asterisk box. No calls going in or out and nothing off hook. Is this normal? Thanks! 5008 ?

Where can I find alaw, ulaw, gsm, g729 formats for native music on hold? I have some mp3 files and I have tried to transcode them to above, but it seams that SOX can't do that. Please, tell me where to download some MOH files (in above formats) or how to transcode mp3? Thank you for your time! -- Tomislav Parcina tparcina#lama.hr

Hi everyone, I''m a bit new to rails, but I have played around with it for the last month. I really enjoy programming in rails and I feel that I should program my new application through this framework. I am very exited when I start creating my scaffolds and views, there is some sense of accomplishment. Now I would really like to make a search function my page that would search through

Hi, I would like to apply the following function for i between 1 and 12, and then construct a list of the return series. for (i in 1:12){ ewma[i] <- emaTA(calm[[i]]^2,0.03) standard[i]<- calm[[i]]/sqrt(ewma[i]) standard <- cbind(standard[i]) } But it does not work. Could anyone give me some advice how can I achieve this? Many thanks -- View this message in context:

Yes, another newbie asking for help. Please bear with me. I don't doubt my problem has a simple solution but it has me stumped. I have a solaris server which carries some confidential financial information on it. I have been asked to install samba on it to share out a particular directory. They obviously want to restrict access to this information. We run a Windows 2003 domain as well.

If I want to wrap two account updates, the syntax is ... Account.transaction(dennis, david) do dennis.withdraw(10); david.deposit(10); end .. where both dennis and david are instances of Account.
