Thank you for quick reply! It is interesting to consider custom R
modules, I did not think about it. I was thinking in the direction
of individual parser for expected R output and it is very useful to
have an example. I'll give it a try.

It's definitely possible. It's also somewhat annoying. If you
actually have made an R module, you could do
r.install_packages(stuff with the repo mentioned)
r.library('my_module')
and that might be the easiest way to gain access. Unfortunately, it's
not very easy to use user-defined functions

exactly what happened
Suppose I have some R code with some functions defined. I would like
to be able to call these functions within SAGE. I did not find any
examples of someone doing so and I was not able to do so myself...
I understand how to initiate R session within SAGE and within notebook
cell, however, it is
I'm trying to use the Sage units package and cannot get expected
simplifications with things more complicated than +, -, /, *. For
example:
sage: a=5*units.length.meter
sage: sqrt(a^2)
5*sqrt(meter^2)
even though I would expect units of simply "meter". If I try to
convert the result to "units.
Also introducing lambda function wasn't necessary:
import scipy.integrate
a=1.0
b=2.0
def fun(t):
if t<=-b:
return -a
elif fhttp://groups.google.com/group/sage-support

HI All
I'm running Sage 4.6.2. I've just noticed that if I evaluate various
symbolic expressions which return 0 then the 0 returned is a python int,
rather than a Sage integer. examples of such expressions are sin(0),
tan(0), ln(0).
Is there a reason for this or is it a bug?
Best wishes
Of course
N=100 in "my" code and repeated
x0=[[0.5*k,0.5*k] for k in range(-10,10)]
in Marshall one are superfluous :)

Can you be more explicit about 'fiddling'? Does that mean you patched
SageTeX, or Sage? Also, is there a } or a ) at the end of the
command?
Thanks! It's true tha
