Hi there! I have become a big fan of the 'foreach' package allowing me to do a lot of stuff in parallel. For example, evaluating the function f on all elements in a vector x is easily accomplished:
foreach(i=1:length(x),.combine=c) %dopar% f(x[i]) Here the .combine=c option tells foreach to combine output using the c()-function. That is, to return it as a vector. Today I discovered the 'bigmemory' package, and I would like to contruct a big.matrix in a parralel fashion row by row. To use foreach I see no other way than to come up with a substitute for c in the .combine option. I have checked out the big.matrix manual, but I can't find a function suitable for just that. Actually, I wouldn't even know how to do it for a usual matrix. Any clues?
