Re: [R] Rserve error

We are missing all the version information the posting guide asked for. Is this 32-bit or 64-bit R? If the former the location of R.dll changed in R 2.12.0, and Rserve would have needed to change too. However, this is not the place for questions/bug reports on Rserve: see http://www.rforge.n

[R] Rserve (Anyone?)

REXP has an asBytes() method. Will this capture the output of an R plot function if a proper graphics device is used? It appears R insists on sending plot output to a file. Kind of strange since it insists on loading all your data into memory before it can do anything. If so then does anyone know
