Hello How can I apply functions along "layers" of a data matrix? Example: daf <- data.frame( 'id' = rep(1:5, 3), matrix(1:60, nrow=15, dimnames=list( NULL, paste('v', 1:4, sep='') )), rep = rep(1:3, each=5) ) The data frame "daf" contains 3 repetitions/layers (rep) of 4 variables of 5 persons (id). For some reason, I want to calculate

Dear R users, I'm having trouble using aggregate() and would greatly appreciate your advice. I am using R 1.5.1 on Windows 2000. I want to call my function in the following way extract.data(x=dat[, "Age", "Year"]) where extract.data() uses aggregate() to count the number of cases for each combination of "Age" and "Year". I've defined

Dear R users, I have some trouble with the aggregate function. Here are my data > daf S_id AF_Class count... R_gc_percent S_length 5 8264497 1 30 0.48 35678 6 8264497 3 7 0.48 35678 8 8264554 1 31 0.51 38894 9 8264554 2 11 0.51 38894 10 8264554 3 1 0.51 38894

Hi all This seems like a very easy question, but I have not found a simple answer to it: If you have a dataframe, how to you plot two of then in different colors depending on a third variable?

Hi, I have a strange problem : some users cannot acces to diretcory, the message is "access denied". The ACL is correct # file: rsrv/vol2/data1/groupes/CORDAF # owner: root # group: Utilisateurs user::rwx user:mro:r-x user:sad:r-x group::--- group:administrateurs:rwx group:daf:rwx mask::rwx other::--- default:user::rwx default:user:mro:r-x default:user:sad:r-x default:group::---

Hi all, I want to do the following: data<-data.frame(col1=c(1,2,3,4,5)) getcol2<-function(data){ data$col2[data$col1<=2]="L" } getcol2(data) Unfortunately in the above col2 does not appear in the final data. So how would you pass this by reference such that you would get it back? Thanks, Sachin [[alternative HTML version deleted]]

In May I had problem with mongrels suddenly consuming huge cpu resources for a minute or two and then returning to normal (load average spikes up to 3.8and then back down to a regular 0.2 over the course of 5 minutes, then again 1/2 hour later. or 4 hours later, no predictable rhythm). I posted to Litespeed forums because I thought the problem was there but didn''t get far. And a week

Hallo Liste Derzeit mache ich meine ersten Gehversuche mit Linux (SuSE). Bis jetzt habe ich in einem kleinen Netzwerk f?r meine Tauchschule vier Rechner betreut. Einer davon war WinNT-4.0 Server und Arbeitsplatz zugleich. Nachdem ich nicht mehr bereit bin, mich mit dem w?chentlichen "blue screen" und dem monatlichen Neuinstallieren von NT abzufinden, bin ich derzeit beim Umsteigen auf

Hi! I heard many things over ogg, but all what i can see is shit. O.K. The oggdrop.exe play with me, have this tool a version number? I can't see it. Every other tool don't run under my system (Win98; Athlon1,5GHz; 768MB RAM). For example every version of oggenc produce the error: "OGGENC.EXE kann nicht ausgef?hrt werden"! There are a german mailing list? An how can i register

Hello R users, I have been using R for a while now for basic stats but I'm now trying to get my head around looping scripts and in some places I am failing! I have a data set with c. 1200 data points on 98 individual animals with data on each row representing a daily measure and I am asking the question "what variables affect the animal's behaviour?" the dataset includes

Hi All, suppose this call flow: there are two Asterisk servers, they are connected through a IAX2 trunk. The users use SIP. The user A on the Asterisk server 1 calls the user B on the Asterisk server 2. They talk for a while and then the user B does an attendant transfer to the user C on the Asterisk server 1. Question: is it possible to optimize the voice flow or the music on hold flow so

Suppose I have the first vector: c(1, 6, 8, 9) I will like to create a second vector of size 10 composed of 0 and 1's. The second vector will be composed of four 1's and six 0's. The position of the 1's will be specificed by the first vector. So essentially, I want a second vector in the form: c(1, 0, 0, 0, 0, 1, 0, 1, 1, 0) Any help is greatly appreciated! -- View this message

I'm sorry to bother this list so much But I haven't programmed in A while and I'm struggling. I have a vector in R of 1's and -1's And I want to use a streak of size Y To predict that the same value will Be next. So, suppose Y = 3. Then, if there is a streak of three ones in a row, then I will predict that the next value is a 1. But, if there is a streak of 3 -1's in

Hello All, Once again thanks for all of the help to date. I am climbing my R learning curve. I've got a few more questions that I hope I can get some guidance on though. I am not sure whether the etiquette is to break up multiple questions or not but I'll keep them together here for now as it may help put the questions in context despite the fact that the post may get a little long.

Hi all, Here's an interesting (for me, at least!) problem I came across: I have a correlation matrix, let's say with 6 variables, A to F, as column headings and the same 6 as row headings. The matrix is filled with correlation coefficients. Therefore, the diagonal is all 1's, and each of the two triangles formed by the diagonal has the same 15 correlation coefficients. I need to

We have a network with Windows NT/2000, SGI's, Linux, Macintosh, AIX. Our user account/passwords for all our machines is handled by NIS on an AIX machine. Our unix machines autheticate through NIS. Our windows machines authenticate by loging on to an NT server acting as the PDC, and that PDC has a service installed on it called "WinDD NIS" (made by Tektronix I think) which contacts
