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: http://www.nabble.com/find-the-index-of-the-smallest-or-biggest-numbe...

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

...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 fit this system in...

...h 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), nrow=4) and it was asked for a compaison of the both matrix-objects and the result should be a vetor with boolean results. I would use this one: as.vector( testmat1 == testmat2 ) or maybe as.vector( t(testmat1) == t(testmat2) ) but the result as a matrix might also be interesting, so as.vector() could be thrown out, and one would get a matrix of results. If you want just to know if a co...

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 ordem crescente sort(x) Ai o problema aplica a fun??o order em x: order(x) ---------------------------------------------------------------------------------------------------------...

...r0, r1 Notice that the four elements of r0 are written by two different instructions. My question is how should I model these sub-registers. If I treat each component as a register, and do the register allocation individually, it seems very difficult to merge the scalars operations back into one vetor operation. // each %reg is a sub-register // r1, r2, r3, r4 here are virtual register number mul %reg1024, r1, r2 // x mul %reg1025, r1, r2 // y mul %reg1026, r1, r2 // z add %reg1027, r3, r4 // w sub %reg1028, %reg1024, r1 sub %reg1029, %reg1025, r1 sub %reg1030, %reg1026...

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

...leaves (at least) me very uneasy. If you are recycling 'test' as well as arbitrary-length yes and no, results will become frighteningly hard to predict except in very simple cases where you have well-defined and consistent regularities in the data. And where you do, surely passing ifelse a vetor of the right length, generated by rep() applied to a short 'test' vector, will do what you want without messing around with new functions that hide what you're doing. Do you really have a case where 'test' is neither a single logical (that could be used with 'if') nor a...

...the ram, the DPglmm is running and it takes about 1 hr to finish running. Then it generates an error message 'Error: cannot allocate vector of size 309.9 Mb'. When I click fit0, i get nothing. I am very frustrated with this. It is very wired that my computer does have enough ram, however a vetor of size 309.9 Mb can't be stored. Thanks very much. xue

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?

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

Well, how many possible permutations are there? Is it possible to model each case as a separate physical register?
