function to find coodinates in an array
Dear list, I am looking for a function/way to get the array coordinates of given elements in an array. What I mean is the following: - Let X be a 3D array - I find the ordering of the elements of X by ord <- order(X) (this returns me a vector) - I now want to find the x,y,z coordinates of each element of ord Can anyone help me? Thanks! Ana

3d from file
Dear all, sorry if it's obvious but I wasn't able to find a solution by myself. I have a text file filled with 3 colums representing xyz coodinates (i.e. positions) of an objects. Can I have in R a 3d plot representig my object' s positions? I guess that I can but I don't know how. Any help is much appreciated Thanks a lot -a- Andrea Valle DAMS - Facolt?? di Scienze della Formazione Universit?? degli Studi di Torino http://w...

non linear quantile regression - Median not plotting where it should
...lem. Curves similar to mine look like these site index curves: http://www.extension.umn.edu/distribution/naturalresources/components/3473-13.html In the example from the nlrq help the lines of the median and the various quantiles all start from the same location, tha is basically (x=0, y=0) in the coodinate plane.  With my problem, the lines start to be drawn from various different positions ( the lines always start at age(x)=0, but the height(y) can range between 0 and 15). Additionally, the data set is quite large. with about 50,000 oberservations on age and height. Does anyone have a suggestion on...

Dropping etheora decoding support for overlapping with oggplay?
...t maybe the liboggplay is going to have more features added) and that they adopt some different programming philophies (e.g., At first I wanted to ask from the user a callback function for setting and reading data in the frame, I droppep in favour of providing a matrix where user could read the i,j coodinate transparently in the colorspace s/he wanted) what may difficult a merge. However, I think there could be advocates of a merge, and I consider the possibily of I myself to become one of them; so I'm changing the schedule to focus on encoding features first. But I'd like to hear from you (a...

extracting coordinates from SpatialPolygonsDataFrame using slot functions
In converting some older code: ## builds an OWIN to generate a set of points on a grid within the OWIN object: bdry <- read.shape( "../../data/boundary.shp" ) outline.verts <- bdry$Shapes[[2]]$verts[1:bdry$Shapes[[2]]$Pstart[2],] outline.order <- nrow( outline.verts ) : 2 bdry.poly <- vector( 2, mode="list" ) bdry.poly[[1]] <- list(
