Matrix indexing in a loop
How do you specify matrix location a[i,j] (or a[i-1,j], etc.) in a "for" loop? I am looking for a flexible method of indexing neighbors over a series of lags (1,2,3...) and I may wish to extend this method to 3D arrays. Example: Data matrix > fun [,1] [,2] [,3] [1,] 1 5 9 [2,] 2 6 10 [3,] 3 7 11 [4,] 4 8 12 For each element a[i,j] in

UNIX diff function
Colleagues, (R: 2.13.0; OS X) I often receive sequential datasets in which there are new rows interposed between existing rows. For example: SET1 <- data.frame(list(LETTERS=LETTERS[c(1:4, 6:10)], NUMBERS=c(1:4, 6:10))) SET2 <- data.frame(list(LETTERS=LETTERS[1:10], NUMBERS=1:10)) > SET1 LETTERS NUMBERS 1 A 1 2 B 2 3 C 3 4 D 4 5

concurrent requests (Rook, but I think the question is more general)
This question involves Rook, but I think the answer will be general enough that it pays to post here. At any rate, I don't know enough to know whether this is a Rook only issue or a general R issue. Here's what I'd like to do (and indeed, have code that should do this): 1. Start R, Rook 2. Start an analysis via a HTTP request to Rook. This analysis uses .Call() to some compiled C

Start R from bash/bat file and end in interactive mode
I have a r-script (rook.R) that starts a Rook server. To present users from having to start R and type in source("rook.R"), I want to create a bash script and bat file that starts R and sources the script. However, to keep the Rook server running R should not close after running the script and stay in interactive mode. This proves more difficult than expected. I tried various

Nearest Neighbors
I was wondering if there is a way in R to find k nearest neighbors of various orders, say order 2, 3, or 4. In otherwords neighbors of neighbors of neighbors. You get the idea. I know that I can use knearneigh(matrix.data, k) but this only gives me the k nearest neighbors and not of a particular order. Thanks in advance. -- View this message in context:

paths and Rook problems only in OSX CRAN binary package?
Hi everyone, I'm trying to diagnose a problem in my R package, but it is a little tricky since it seems to occur only with the Mac OSX CRAN binary build. My package starts a Rook server and opens a browser. On my own system (details below), when I build the package, I have no trouble. The Rook server starts and the page loads in the browser. However, if I've installed it from CRAN, I

how to find near neighbors?
I am looking for an efficient way to find near neighbors... More specifically... I have two sets of points: A & B and I want to find points in set B which are closer to set A than some cutoff (or n-closest) I will appreciate very much any pointers...

Finding the neighbors of the point
Dear all, I got point data of trees. I was wondering if anybody has experience in searching the neighbors within a specified distance efficiently. X Y Z 99 34 65 98 35 29 98 34 28 99 33 33 98 32 23 99 33 21 99 33 22 99 32 24 99 30 23 ... What I want to do is : searching for the neighbors with a distance R for each tree & the neighbor must have a bigger Z.

Hola Freddy. Yo parto de un shape en que tengo los típicos archivos .shp, .sbx, .sbn, .shx y .dbf. En la tabla tengo el área de los poligonos en m2, el perímetro, el estado y el código ISO del estado dispuesto por el SGM. ¿Me puedes orientar un poco más? Gracias, Sebastían.

R encrypt/decrypt
Hello, I am working on a web system (php) that uses R in the backend, and we need some basic fast encryption/decryption for the underlying mysql database that can be used by both R AND php. It does not need to be top-of-the-line, but just provide some basic level of fast encryption/decryption. Any suggestions? Thank you, Ramiro [[alternative HTML version deleted]]

Sparse KMeans/KDE/Nearest Neighbors?
hi, I have a dataset (the netflix dataset) which is basically ~18k columns and well variable number of rows but let's assume 25 thousand for now. The dataset is very sparse. I was wondering how to do kmeans/nearest neighbors or kernel density estimation on it. I tired using the spMatrix function in "Matrix" package. I think I'm able to create the matrix but as soon as I pass
