Perhaps a named pipe (aka fifo) would solve your problem? You could write to it from an arbitrary process and read from it from your R program.

I have tryed various things and none did work cleanly. One possible solution is to use the pipe() function inside R and to pass in the "cat inputData" however this is not very convenient since I would like to use variable commands to generate the inputData which are much more complex than just "cat inputData" they might consist themselves of multiple pipes. The problem is that R uses the stdin for itself to read commands and I could not find any solution. Thanks a lot, Alberto ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help ------------------------------------------------------------------------------ ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
