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]]

...expected, but I fail to provide the a=100 in the constrained case: > constrOptim(c(-1.2,0.9), fr, NULL, ui=rbind(c(-1,0),c(0,-1)), ci=c(-1,-1),a=100) Error in f(theta) : Argument "a" is missing, with no default Is this a bug or is there a different solution that I miss here? TIA, Marlene

...,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. [[alternative HTML version deleted]]

...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 HTML version deleted]]

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 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. I don't know how to do that and if it is possible to do it with this package. Someone have some idea. Any help would be much appreciated. Marlene [[alternative HTML version deleted]]

...CRAN. El paquete implementa diferentes modelos de inventario, el efecto látigo y otras variables de desempeño de la cadena de suministro.

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

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,

Dear maintainers of the parallel package, I ran into an issue with the parallel package in R-3.1.0. The following code prints the message "NULL!" quite a lot. library(parallel) for (n in 1:1000) { p <- mcparallel(sqrt(n)) res <- mccollect(p, wait=FALSE, timeout=1000) mccollect(p) if (is.null(res)) cat(n," NULL!\n") } It does not happen in
