Dear R experts, How to find out the index of minimum or maxmum number in a vetor or data.frame? For example, a= n price 1 50 -2 100 0 200 -1 300 ...... I want to find out the row which the n is the smallest or largestest and extract the price. Thanks Ted -- View this message in context:

I have not been able to find any programs for running vector autoregressions with R. I am interested in running Bayesian VARs and also running VARs that run all combinations of variables in the vector. Is anyone currently developing this? -Nirav Mehta

Hi, I have a vetor os dates with day and hour:minutes. > time1 <- c("03/08/08-11:00","03/08/08-11:10") > time1 <- as.Date(time1,"%d/%m/%y-%R") > summary(time1) Min. 1st Qu. Median Mean 3rd Qu. Max. "2008-08-03" "2008-08-03" "2008-08-03" "2008-08-03" "2008-08-03"

...elements to the new st.dev column would be zero (c(rep(0,3)), then the 4th element of the new std.dev column would be standard deviation of the first 4 closes. Next element would be sd of Close[5]:Close[1], then sd of Close[6]: Close[2] ...and so on until the last row of xyz. There must be an easy vetorized way to do this but I don't see it. Sorry for the basic question but continuing to figure this new language out.

Hi R-masters I have this system of equations R(x,t)= a(t)+b(x,t) a(t) = c + d*t b(t) = e + f*t where x is a vetor of age<-c(37,42,47,52,57,62,67,72,77,83), t is vetor of year (1980:2000) R(x,t) = Rate of mortality in age x on year t a(t) = base mortality on year t b(x,t) = exponential rate of mortality for age x on year t b(t) = exponential rate of mortality on year t I wish is possible

Hello, sorry for posting this independently of the original thread, but it is not that easy to answer to mails, when receiving the r-help as digest... ... The question was: > I compare each row of a matrix with each row of another matrix. > > testmat1 <- matrix(c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16), nrow=4) > testmat2 <- matrix(c(1,2,3,5,5,6,7,8,9,10,11,12,13,14,15,16),

Ol? amigos tudo bem ? Espero que sim. Sou novo aqui e gostaria muito da ajuda dos senhores para resolver um pequeno probleminha no R. Ent?o, estou com um probleminha com uma atividade que relaciona duas fun??es no R, ? o seguinte: Primeiro atrav?s da fun??o sample ? criado um vetor aleat?trio: x <- sample(1:100, 20) Depois aplico a fun??o sort que tem como objetivo ordenar os elementos em

Hi! With the following script, I'm trying to make a demonstration of a Confidence Interval, but I'm observing some differences on tails. # Teste de média entre uma amostra e uma população normal # Autor: Raphael de Freitas Saldanha # Agosto de 2008 n <- 200 # Sample size xbar <- 100 # Sample mean s <- 2 # Sample SD nc <- 0.95 # Confidence level (95%

It seems to me that LLVM sub-register is not for the following hardware architecture. All instructions of a hardware are vector instructions. All registers contains 4 32-bit FP sub-registers. They are called r0.x, r0.y, r0.z, r0.w. Most instructions write more than one elements in this way: mul r0.xyw, r1, r2 add r0.z, r3, r4 sub r5, r0, r1 Notice that the four elements of r0 are written

Good Afternoon, ?? I have a small problem with the following code. # The x.sub$Time[[1]] 2006-10-31 19:03:01 EST # when put in variable star give-me star<-x.sub$Time[[1]] print(star) print(x.sub$Time[[1]]) [1] 1 36 32 -........ do not understand why -- View this message in context: http://r.789695.n4.nabble.com/problem-with-data-tp4453510p4453510.html Sent from the R help mailing

Hi everyone, I'm currently working on a new function merging optimization that is more general than the current LLVM function merging optimization that works only on identical functions. I would like to know if the community has any interest in having a more powerful function merging optimization. ---- More Details ---- Up until now, I have been focusing on the quality of the code

Hi Hal, Because my function merging strategy is able to merge any two function, allowing for different CFGs, different parameters, etc. I am unable to use just a simple hash value to compare whether or not two functions are similar. Therefore, the idea is to have an infrastructure which allows me to compare whether or not two functions are similar without having traverse the two function

For S Ellison, just clarifying, I am Suharto Anggono, not Martin Maechler. "Martin et al.," from my previous E-mail was the beginning of message from Gabriel Becker, that I quoted. The quoted "still a bit disappointed that nobody has taken a look" is from Martin Maechler. In all of the proposed 'ifelse'-like functions so far, including from me (that I labeled as

Hi, My computer has 2GB of ram and I also request 2GB of virtual ram from c drive, therefore totally I have 4GB of ram. Before I open R workshop, I also add "C:\Program Files\R\R-2.5.0\bin\Rgui.exe" --max-mem-size=3000Mb--max-vsize=3000Mb" into the target of R by right clicking the R icon-properties. I am running a program (DPglmm), which is built in DPpackage. The program is

Dear all, There is something I'm missing in order to understand the following behavior: > aa <- c("test", "name") > ifelse(any(nchar(aa) < 3), aa[-which(nchar(aa) < 3)], aa) [1] "test" > any(nchar(aa) < 3) [1] FALSE Shouldn't the ifelse function return the whole aa vector? Using if and else separately, I get the correct result... >

HI, R user, I generate the vectors with the same length. I want to put each vector into each column of data frame. Why it doesnt work`? rm<-data.frame() for(a in 1:6){ rm[,a]<-getmeasure(p1,a,speech) } thanks a lot Tammy _________________________________________________________________ Share your memories online with anyone you want.

Hi, Seems that on RWin 1.7.0 and 1.6.2 isSeekable returns F on binary files, while seek() works as expected on the same connection - see example below: > con = file(nm, "rb") > isSeekable(con) [1] FALSE > readBin(con, double(), 10) [1] 7.263824e-317 5.968155e-317 2.340685e-317 2.734062e-312 4.088386e-312 4.670335e-317 [7] 6.097545e-317 3.396341e-312 6.615484e-317
