[R] plot() under Rserve

[Jonathan Shore]

Hi,

Rserve allows one to render plots into jpeg with R code such as:

   jpeg(filename, ...)
   plot(...)
   dev.off()

However, substituting png, tiff, or bmp device redirection fails on Rserve
with "eval error" on OSX.  

   png(filename, ...)
   plot(...)
   dev.off()

The above in an eval produces an error and sometimes faults the connection.   
I suspect that Rserve is run in a mode where certain graphics parameters or
shared libraries are not available?

Has anyone tried to render with Rserve to a device other than jpeg?   The
Java client demo uses jpeg, but will fail if changed to png.

Thanks

Jonathan
