I want to create a new array which selects values from an original array based on a function of the indices. That is: I want to create a new matrix Vnew[i,j,k]=Vold[i,j,ks] where ks is a function of the index elements i,j,k. I want to do this WITHOUT a loop. Call the function "ksfunction", and the array dimensions nis,njs,nks. I can do this using a loop as follows: # Loop version:

Hi, I need to be able to run an R script by double-clicking the file name in Windows. I've tried associating the .r extension with the different R .exe's in /bin but none seems to work. Some open R then close right away, and Rgui.exe gives the message ARGUMENT "/my/file.r" __ignored__ before opening a new, blank session. I've tried Google and looking in the R for

Hi folks, I am having trouble accessing sub-functions when the main function is stored in an array. For example, the following test code works fine: fcns = c(abs, sqrt) fcns[[1]](-2) fcns[[2]](2) However, when I try to access sub-functions declared within list() in a function, this only works directly. When I try to access these within an array only the first declared sub-function is run.

Hi, I have 20*60 data matrix (with some NAs) and I wish to perfom a Pearson correlation coefficient matrix as well as simple linear regression equation and coefficient of determination (R2) for every possible combination. Any tip/idea/library/script how do to so. Thanks, As hz -- View this message in context:

...ry close to the boundary, which will make optim(..., hessian=TRUE) or optimHessian() fail, as they do not follow the box-constraints, and hence estimate the function in the unfeasible parameter space. As a simple example (my problem is more complex though, simple param transformations do not apply ashere), imagine estimating mu and sigma (restricted to be >0) of a simple normally distributed data, where however the true sigma is very close to zero: LLNorm <- function(para, dat=rn) return(-sum(dnorm(dat, para[1], para[2], log=TRUE))) rn2 <- c(rep(10.3, 2000), 10.31) >optim(c(10,1), f...

Does anyone know how I might be able to use the Javascript libs that come with Samba 4 to create a web page that can search Active Directory (an actual MS AD server)? I looked through the SWAT pages, but I didn't get a sense of how to use it (or if I could). I know this is not a strictly Samba question, but I'd like a platform independent way to access an AD server and this seems

First of all I should say this email is more of a general statistics questions rather than being specific to using R but I'm hoping that this may be of general interest. I have a dataset that I would really like to use PCA on and have been using the package pcaMethods to examine my data. The results using traditional PCA come out really nicely. The dataset is comprised of a set of questions
