I have no idea. I hope someone who coded the notebook will answer
this.

Yes, as I said it starts automatically but it must have no descriptive
comment above the cell. That is a worksheet with only one naked cell
and no description in it.
That's why I suggested to start a new worksheet

Thank, that helped a lot. In Python documentation I found the
solution.

This question may sound somehow out of place, but maybe you can offer
some help.
Where in the documentation did you find something about this fancy
notation to include variables into your

I feel, this should be documented somewhere.
I used http://tutorial.sagenb.org/pub/4/
for reference.
Best regards

Thank you for this enhancement. The curve looks nice. However only in
this example the bell-shape can be appreciated.

Problem solved!
The simple '._sage_()' does the trick. It converts data from R into
something that can be handled by Python or Sage.
def ndistribpts(x): return (x,r.dnorm(x,mean=100,sd=25)._sage_())
def cube(x): return (x,x*x*x)

people successfully eliminated by installing the libraries mentioned

It was probably silly to assume that all build essentials are
installed by default.
Thank you for your help

Hello,
I just learned that @interact provides a fantastic tool to test
mathematical models. I understand that these interactive frames are
some sort of Java applets. I wonder If there is a way to export these
applets and to make it usable on an ordinary webpage.

I encountered a problem when starting sage. I received the error
message listed below and sage did not start.
As stated removal of the text file solved the problem provisionally.
Sage did start and elementary functions could be performed but not for
