Hi. Can anyone suggest a simple way to obtain in R a list of vector coordinates of the following form? The code below is Mathematica. In[5]:= Flatten[Table[{i,j,k},{i,3},{j,4},{k,5}], 2] Out[5]= {{1,1,1},{1,1,2},{1,1,3},{1,1,4},{1,1,5},{1,2,1},{1,2,2},{1,2,3},{1 ,2,4},{1,2, 5},{1,3,1},{1,3,2},{1,3,3},{1,3,4},{1,3,5},{1,4,1},{1,4,2},{1,4,3}, {1,4,

Hi, I have a dynamic programming problem with many state variables, let's call them l, n, m, etc. The transition probabilities are originally given in an array form, eg transtition[l,m,n,ll,mm,nn] give the probability of going from l,m,n to ll,mm,nn. However, the numerical solution is best handled when I "flatten" the L x M x N state space into a single one (call it S), ie a

Greetings all! I have been searching the Site for a function, say "subsets", such that for instance subsets(10) would return a (say) matrix of indices to the 2^10 subsets of N items -- perhaps in the form of 2^10 rows each of which is 10 entries each either TRUE or FALSE. Or 1 or 0. Or ... I can of course write my own, using good old looping technology or similar, but it would be

Hi Everyone, I am running into a problem with matrices. I use R version 2.4.1 and an older version. The problem is this: m<-matrix(ncol=3,nrow=4) m[,1:3]<-runif(n=4) That does what I expect; it fills up the rows of the matrix with the data vector > m [,1] [,2] [,3] [1,] 0.2083071 0.2083071 0.2083071 [2,] 0.5865763 0.5865763 0.5865763 [3,] 0.7901782 0.7901782

Hi all, I'm learning R. I'm used to Matlab and am having the following issue: I define a column vector and matrix and then multiply them. The result is not what I expect: v2 <- c(0,1,0) M <- cbind(c(1,4,7),c(2,5,8),c(3,6,9)) M*v2 [,1] [,2] [,3] [1,] 0 0 0 [2,] 4 5 6 [3,] 0 0 0 I expect the result to be a column, specifically the 2nd column of M.

I'm looking for a good form in which to store matrix results of a simulation. I am doing a simulation study. Each simulation generates some data and then analyzes it. I want to record the results of many simulations and analyze them. Say r has the results of one simulation, and I care about r$coefficients, a vector of coefficients, and r$var, the estimated covariance matrix. I'll do
