Two 3D cones in one graph
Dear R-users: The following code produces two cones in two panels. What I would like to have is to have them in one, and to meet in the origin. Does anyone have any good ideas how to do this? Thanks for your help Jaakko library(lattice) A<-matrix(ncol=2, nrow=64) for(i in 0:63) { A[i+1,1]<-sin(i/10) A[i+1,2]<-cos(i/10) }

Programming using formulas
...archical structure, is it the "|" and how can I restrict the number of hierarchical levels? And how to use in this context, the data, subset, weights and na.action arguments? In case you are wondering what I plan to implement, one references for example is: Haataja, R., Larocque, D., Nevalainen, J. and Oja, H. (2009).

uniform sampling without replacement algorithm
Let us consider the current uniform sampling without replacement algorithm. It resides in function do_sample in https://svn.r-project.org/R/trunk/src/main/random.c Its complexity is obviously O(n), where the sample is selected from 1...n, since the algorithm has to create a vector of length n. So when the sample size is much lesser than n, the algorithm is not effective. Algorithms with
