It is a bug, and I am stunned. Same here on Debian testing with [EMAIL PROTECTED]:~> COLUMNS=78 dpkg -l r-base-core python-rpy python2.4 python2.5 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii python-rpy 1.0.1-1 Python interface to the GNU R language and e ii python2.4 2.4.4-7 An interactive high-level object-oriented la ii python2.5 2.5.1-6 An interactive high-level object-oriented la ii r-base-core 2.6.1-1 GNU R core of statistical computing language so everything should be current. I don't know what's going on -- so forwarding to Greg. On the other hand, running the 'animation.py' and 'chisquared.py' examples still work. Faithful.py is missing its .dat file. Also, running the regression tests seem to work. So with that I turned back to the example. Removing the "type='lines'" makes it work: [EMAIL PROTECTED]:~/src/debian/Python/rpy-1.0.1/tests> cat /tmp/rpybug.py from rpy import * degrees = 4 grid = r.seq(0, 10, length=100) values = [r.dchisq(x, degrees) for x in grid] r.par(ann=0) r.plot(grid, values) [EMAIL PROTECTED]:~/src/debian/Python/rpy-1.0.1/tests> python /tmp/rpybug.py [EMAIL PROTECTED]:~/src/debian/Python/rpy-1.0.1/tests> So back to Greg: what is that make plot kill python over the type argument?
