This one did not make it to the list when I first sent it: Building on Thomas Baier's clever design for the (D)COM server for R on Windows what I need is Evaluate (returns an array) EvaluateNoReturn (cmd as of now) GetSymbol (assign value to AS variable) SetSymbol (set R variable to value of AS variable) If AS itself does not allow large matrices as values for variables (I still have to learn AS ;-) then a direct transfer of a matrix from R to an Excel range also could be a solution. If AS cannot do large matrices, we cannot use Evaluate, but we can do an assignment in R and transfer the variable directly to Excel.
