Hi!
I've been trying to apply your advices and this is the result:
First I tried the just downloaded 4.8 ova file and the sagenb.org server. In both cases the result is the same, that is:
The instructions:
x=r([1,2,3,4,5])
y=r([1,2,3,2,1])
r.plot(x,y)
work fine.
However, when I write:
x<-c(1,2,3,4,5)
y<-c(1,2,3,2,1)
plot(x,y)
and try to compile with 'R', I don't obtain any error message, but the graphic is not shown. That is, I obtain an empty output.
Finally I tried with my ubuntu 10.4. and sage 4.8. I installed packages libpango1.0-dev and libcairo-dev with xorg-dev previously installed. I got an error that says 'Unable to start r' So I guess this is a matter of my lack of competence in linux and not a general problem.
