Thank you Joal,
I tried and that works perfectly.
The trick is to start the device and close it at each picture.
It's a sensible way to work.

I'm using sage for preparing a notebook with some R computations and
plots.
I set the language of the worksheet to R.
I noticed that plots appear later in the worksheet
after the commands are issued and then they may overlap.
Example:
sage: x = rnorm(10)
sage: x
[1] -2.92886581 -2.21814906 -1.06
I read in the listing of the function
warnings.warn("""\
scipy.stats.corrcoef is deprecated; please update your code to use
numpy.corrcoef.
Please note that:
- numpy.corrcoef rowvar argument defaults to true, not false
- numpy.corrcoef bias argument defaults to false, not true

Thank you so much Ahmed!
Your answer was really clear
and the solution (for this and
other cases) works perfectly.
It appears that is crucial
to understand how conversions
work in Sage.

I would like to sample from a multinomial distribution.
What's wrong in the following statements in sage 4.0.1?
>>> import numpy.random
>>> numpy.random.multinomial(10, [.5,.5], size=20)
Thank you

Dynamic Sage notebooks are really amazing.
I'm also an R user and I would like very much
to use sage to create notebooks with statistical examples
in R . Is this possible?
By the way , I thought it was allowed to execute
R code within an R notebook.
However I tried to change the interpreter to
I have Linux Ubuntu 8.04. 32 bit
I downloaded Sage 3.4
sage-3.4-linux-Ubuntu_8.10-i686-Linux.tar.gz
Sage starts correctly but
after notebook()
I get an error as follows.
Any suggestion ?
Thank you

Is there a simple way to define
a method that adds labels to the vertices
of a graph or digraph? I would like to have
something like
G.show(labels = ['a', 'b', 'c'])
when G is a graph with vertices [0,1,2].
Apparently, this is possible for graphs defined as
dictionaries, but not for graphs de
Thank you Lars,
I had the feeling that this behavior
should be something related to Python,
but I was impressed by the inconsistency,
because in my first example everything
worked as (I) intended.
So, if this is a feature of Python I
have to study it carefully !
Best regards

On Dec
The following behavior is very confusing to me.
I define a program
def test(a):
b=a
b = a^2
return b
Then if I assign
x = 2
and then execute
test(x)
4
I get x squared and x unchanged:
x
2
However suppose now that I want the same on a single
element of a matrix and define
11 matches
