Hi, I need to repor the index of a min value of each row in a matrix, but I don't know how to do that when I have more than one min value. Here is my example > dat <- matrix(c(5.4,4.8,5.6,4.8,NA,4.4,4.6,3.4,NA,NA,4,2.4,NA,NA,NA,2),byrow=TRUE,ncol=4) > dat [,1] [,2] [,3] [,4] [1,] 5.4 4.8 5.6 4.8 [2,] NA 4.4 4.6 3.4 [3,] NA NA 4.0 2.4 [4,] NA NA NA 2.0

Hi R-users I'm writing a code to run a fuction but I found an error that I can't fix. I reproduced the error with a simple example. The correct answer is k but I can't fill my s matrix. What I'm doing wrong? s<-matrix(data=NA,nrow=1,ncol=5 ) s for(i in 1:5) { k=sqrt(i) s[,i]<-k[i] print(k) } s Thanks in advance, Marlene. [[alternative

Dear R-user Suppose I have the following data y=c(2,1,5,8,11,3,1,7,50,21,33,7,60) x=data.frame(y) for(i in 4:nrow(x)) x[i,] =var(x[i-3:i-1,]) I'm trying to get a new variable with the variance of the 3 previous values (just an example) and with NA in the three first positions. I know that my for() is wrong but I'm not able to find my error. Any idea? Thanks, Marlene.

How can I use a function with some additional input parameters in constrOptim? For example, something like fr <- function(x,a) { ## Rosenbrock Banana function x1 <- x[1] x2 <- x[2] a * (x2 - x1 * x1)^2 + (1 - x1)^2 } where the optimum is to be found w.r.t. x. Calling optim(c(-1.2,1), fr, NULL, a=100) works as expected, but I fail to provide the a=100 in the constrained case:

Hola buenas, me preguntaba si alguno usa hadoop Spark en su día día y si me podíais recomendar un buen curso para empezar. Estuve en la charla de meetup de madrid hace unos meses de Rspark y estuvo bien, ahora me preguntaba si es posible profundizar. Pero me gustaría tener recomendaciones de cualquier material que podáis recomendar, cursos de coursera que hayais hecho, libros que hayais leido,

Hi all, I''m trying to get text on to the screen in response to pressing a button. This code doesn''t work, and I don''t know why. My puts command says that the window is shown, but it''s not displayed. Also, it seems to me that there should be an easier way to get text on a screen in response to pressing a button. Any hints? Thanks! Marlene require

Hi, I am translating some Gauss code to R. Gauss has an interesting way of handling constraints. Observe the following code snipplet: e1 = x[.,23] .eq 0; @ remove obs with Regular Hours = 0 @ e2 = x[.,12] .gt 1; @ remove obs with non-regular work status @ e3 = x[.,4] .lt 15; @ remove obs with agricultural and mining industry code (< 15)@ esum = e1 + e2 + e3; e = esum .gt 0; @

Dear all, I'm using zeroinfl() from the pscl-package for zero inflated Poisson regression. I would like to calculate (aproximate) prediction intervals for the fitted values. The package itself does not provide them. Can this be calculated analyticaly? Or do I have to use bootstrap? What I tried until now is to use bootstrap to estimate these intervals. Any comments on the code are welcome.

I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves. I then encoded it with a couple of different frame sizes and sample rates. There were some small differences, but nothing horrible. So, I decided to run with 24KHz sample rate with 16 bit samples. This seemed like a reasonable tradeoff against the quality degradation that my folks

Dear List, I just tried installing R 1.1.1 on SuSE 7.0 and encountered some problems. Using the precompiled binaries, I had a failed dependency: R was looking for "libblas.so.2" and apparently didn't find it. I then tried compiling from sources, which failed with the message: "/usr/bin/ginstall: zero.so No such file or directory" (or something to that effect). I'm

I have a data frame (df) with colums x, y and z. e.g. df <- data.frame(x = sample(4), y = sample(4), z = sample(4)) I can extract column z by: df$z or df[3] I can also extract columns x,y by: df[1:2] or by df[-3]. Is it possible to extract x,y columns in a "symbolic" fashion i.e. by equivalent of df[-z] (which is illegal) ??? Or alternativeley, is there an equivalent of

If you reply, please be careful that replies go to the right place: r-bugs if your comment is specifically about the bug (and it contains the PR# in the subject that will be added when this is cc'd to r-devel), r-devel if general discussion, not both.
