Hi,
> sage: install_package('sage -i r-2.6.1rc.p1')
I actually installed through command line, but it's mostly same - it
went ok, but.....

I had to edit manually in 2 places, first $SAGE_HOME/local/bin/R has
variable R_HOME_DIR pointing to build dir instead of install dir,
after changing it to right dir I was able to import rpy, because
before it failed...

I did:
sage: from rpy import *
and it worked so quite ok... but not exactly yet :)... at first when I
wanted to check r object I was getting traceback about missing
variable, after change in file rpy.py in line 312 from
Rver = self.__getitem__('R_version_string')
to
Rver = self.__getitem__('R.version.string')
it started to report version, it said:
RPy version 1.0-RC3 [R version 2.6.1 RC (2007-11-24 r43532)]
so ok...

that test works like a charm...

I noticed Integer -> int problem when I was trying
http://rpy.sourceforge.net/rpy_demo.html, got without glitch to some
place, now I try to get:
sage: r.png('faithful_histogram.png',width=int(733),height=int(550))
but no luck currently, anyway I'm still looking around... :)

Andrzej.
PS.: maybe this should be in separate topic or other list? currently I
use only "reply" from browser, but I think there will be lot more
reports about this :)
