Hi R users, Someone knows how to replace Infinite value by zero. I have a vector with some Inf value and I want to substitute these values by zero to get the mean of the components of the vector. Any idea? Many thanks, Marlene. [[alternative HTML version deleted]]

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.

Dear R users, I'm running a SVR in package e1071 but I did not able to calculate the parameters w and b of the regression.

Hola amor! Finalmente llegué a D.C. Ya estoy en el albergue pero el cuarto solo va a ser liberado a la una o tal vez dos de la tarde. Pero no importa al menos ya estoy aqui, ya tomé desayuno que por cierto es horrible. Voy a poder tomar baño y usar un locker por un dolar. Entonces voy a tomar baño guardar mis cosas y salir ya que aqui no hago nada. Cómo fue tu domingo? Cómo está Esteban? El

I've moved this from r-help to r-bugs. 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.

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:

Okay, looking at the docs, then it's not a bug, since the "..." argument is not actually documented as "other arguments passed to f or grad". However, that *is* how it's document in `optim', so one can see how this might cause some confusion. Now, it's not clear to me which other arguments need to be passed to `optim' except perhaps `hessian'. Am

This is probably something very simple but I can''t seem to figure out why I keep getting the ''wrong number of arguments (1 for 2)'' error with the following code when I try to create a new record.

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

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

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,
