Hello kanglin:
Try to transfer from Java Object JList to R Object Data.frame, you
could use
public Rconnection r_connection = null;
.....
.....
this.r_connection.assign("dataframe_ex",java list_ex);

This is fixed now, in R-patched and R-devel.

A later bug report (#7860) had to do with inappropriate sizing of the
first text drawn on a png() device, and I've now fixed the bug that
caused that. Could you please check whether you still see your bug on
today's build? It will be available on CRAN tomorrow (May 15), in
http://cran.r-project.org/bin/windows/base/rpatched.html
Thanks!

Subject: [Rd] Specifying dependency on a specific patched version
To: r-devel at stat.math.ethz.ch
Message-ID: <971536df05051420525ce1e1b5 at mail.gmail.com>
Content-Type: text/plain; charset=ISO-8859-1
Is there a way to specify a package dependency in the Depends:
field of the DESCRIPTION file for a specific patched version of a
specific OS?
For example, today's Windows patched release (2005-05-14) has
the capability of changing the time zone within R on Windows
via Sys.putenv(TZ="GMT") but prior patched versions do not have this.
Is there some way of ensuring that the 2005-05-14 or later release is used
if on Windows only?

R as a to be converted to a data.frame?
