Thank you, Greg, and also to Scott Ellison, who replied privately. I am in the process of trying out both suggestions. After I sent my initial message, I came across the Systemfit package, which allows specification of constraints on parameters. In theory, this should solve my problem perfectly. However, I was not able to get it to work with my data, as every attempt yielded the following

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.

The problem I''m solving here is that I have two different Rails applicatons that uses the same domain name. One handles the www (e.g. www.mycoolapp.com) and is used as the main site, and the other handles the user subdomains (e.g.. someuser.mycoolapp.com). The DNS stuff and the Apache virtual hosts were all set up, the two rails apps are in place in the file system, and the proper

Hello all, It 's dificult to explain; The system I need is an box option (based on *), that I would add to an existing PABX (ie: Nortel with 600 ext). I need two E1/T2 card to plug the system between Telco (FT) and PABX (Nortel)! One card for France Telecom Side (E1a) and one other to Nortel Side (E1b). --------- -------- ----------- Telco FT

Hi, I have a string in a controller that represents a url for my website. For example the string might be /cont/act/id and I want to break this up using the routes defined in my config/routes.rb file so that I get a hash like {:controller => ''cont'', :act => ''act'', :id=>''id''} How can I access all of the information stored in

Hi, is there any direct R function to write an diagonal matrix in an opposite way? for example I want to get like:   > diag(rnorm(5))[,5:1]            [,1]       [,2]       [,3]      [,4]       [,5] [1,]  0.0000000  0.0000000  0.0000000  0.000000 -0.1504687 [2,]  0.0000000  0.0000000  0.0000000 -2.139669  0.0000000 [3,]  0.0000000  0.0000000 -0.2102133  0.000000  0.0000000 [4,]  0.0000000

Nurza, Try running a while loop steping out until you have a start and finish thats the function is opposite in sign. You need a "start" and "finish" where F is + and - on either side of the loop. Graphing F might help. step<-10 checkme<-F(start)*F(finish+step) while(checkme>0){ initialstep<-initialstep*2 checkme<-F(start)*F(finish+step) }

Or to put it another way, is there a function f, such that Inflector.f(Inflector.Camelize(x)) = x ? Enquiring minds need to know. Adelle.

Hi Rusty, The two similar functions in vringh and virtqueue for turning on interrupts has opposite return values if there are buffers available in the ring. I think it would be better if these two functions aligned the use of return values. Maybe it's just me, but I got the logic for re-scheduling NAPI wrong due to this. /** * vringh_notify_enable_kern - we want to know if something

Does getelementptr have a counterpart function which unindexes a pointer? In particular, I'm using CreateStructGEP from the builder and want to get back to the struct pointer from a member pointer. fptr = b.CreateStructGEP( sptr, 2 ); //I want to do this sptr = b.CreateUnStructGEP( fptr, sptr_type, 2 ); I know I can calculate the offsets on my own, but it'd be nice to not have to since

Hi, I'm connecting Asterisk v. 1.4.10 to Zanzibar Open IVR that acts as a SIP trunk. Since recognition didn't work correctly, I've troubleshot with Wireshark and saw that RTP stream is first send to one port on SIP trunk and then when first RTP packet arrives in opposite direction (from TTS part of Zanzibar - it's a prompt) Asterisk starts sending to the same RTP port -
