Hi,
I've been using Python for many years and recently installed Sage on
my MacBook Pro running OS X. So far I'm liking it quite a bit.
What is the best way to add support for a package not included in
Sage? I'm currently using a serial link (later to be Ethernet) to send
packets from the Mac to

Forgive me if this is too obvious. I'm still evaluating/learning the
basics of SAGE
Just how compatible is SAGE with Python? By which I mean, should I be
able to just "drop-in" an existing/working python script and have it
run, or should I expect some modifications will be required? And if
so,

When I try to plot a previously assigned data set using rpy:
from rpy import *
r.plot(x,y)
i get this:
Traceback (click to the left for traceback)

Hi,
Are algorithms like PSLQ available?
If yes, please give a simple example so that I fully understand the
commands.

Sorry for coming in late on this. One should really use the

hi,
i ran into an error using sage (from the command line).
i tried this on 'ubuntu 8.10 (intrepid)' on an intel pentium.
(the very same script works perfectly well on 'ubuntu 6.10 (edgy)'
on an amd64.)
the script test.spyx:

No, it's interpolation. Calculating the exact solution is actually a
problem due to high frequency components and disturbances.
Interpolation tries to avoid

Taking example from the tutorial:
c=circle((0,0), .5, rgbcolor=(1,1,0))
c.show(figsize=[5,5])
shows me a well-proportioned circle.
My question is how do I save this circle to file?
save(c, filename="plot.eps")
exports ellipse which it should. Controlling aspect ratio in show()
seems to be the only
I just compiled Sage 3.2.2 on a Linux 32 bit machine running the

When I log in as a user "george" and try to evaluate 2+2 within a Sage
notebook by using Magma, I get the following error message. On the
other hand, Maple works
