How to write to stdin with rjava's jri

Question

I am looking for a way to pipe a file to an R script using jri. I don't want to read the file in from the R script but rather pipe it directly into stdin with jri. Is there a way that I can get a file handle in jri that is connected to stdin and write to it. I have been looking at the code and it does not appear to be accessible.

Thanks in advance,
