R help - Mar 2003 - How to draw several plots in one figure?

Hey,

I want to draw several plots sequently, but have to make them dispaly in one
figure.
So how to achieve this?

Thanks.

Fred

See help(layout).

Thanks, Su.

But I want to plot the several plots in the same
x-y axis setting, not in multiple subplots.

One way is to make inital plot:
>plot()
Then build other data into the plot using:

lines()
points()
etc.
see help files for those

Alternatively:

set par(new=T)
then plot again and the device wont be cleared

Dear Feng and everybody

I still have my list of "how to" things for R and sometimes I even try
to add more.  Here's the address

http://lark.cc.ku.edu/~pauljohn/R/statsRus.html

I can't tell if you want to have several plots on the same page, in 
which case you should use this item:

http://lark.cc.ku.edu/~pauljohn/R/statsRus.html#5.1

Of if you want a full overlay onto the exact same piece of paper, in 
which you should look at:

http://lark.cc.ku.edu/~pauljohn/R/statsRus.html#5.11

When I first put up the R tips page, several of the R regulars checked 
it over for errors, but it has probably been a year or two since I got 
any advice, constructive or otherwise.  I know new users still sometimes 
find it because I get follow up questions, but I'm always glad for more 
help.  So, in case anybody has corrections or updates, please let me know.

Do you want numbers?  If yes, did you try programming KL(theta) as a 
function, then computing

D.KL <- (KL(theta+delta)-KL(delta))/delta

for some suitably small delta?

If the limits of integration do not include theta, then you can 
interchange the order of integration and differentiation.  To go beyond 
this, I think I would need more specifics.

Spencer Graves
p.s.  You''ve got the negative of the standard KL divergence;  see,
e.g.,
"http://www.cis.hut.fi/aapo/papers/NCS99web/node26.html".

Hey, R-listers

I was totally confused by a seemling simple first derivative
function.
Given the Kullback-Leibler divergence function between
a true pdf function P(x,theta) and an approximation pdf
function Q(theta)=q1(theta1)*q2(theta2)*...*qn(thetan),
where theta=[theta1,theta2, ..., thetan]''.
KL(Q||P) 
= \integration Q(theta)*log(P(x,theta)/Q(theta)) dtheta

So how to derive the first derivative of KL with respect 
to theta1?

Thanks for your helpful advices.

Fred

Not for calculation on numbers, 
just to derive the symbolic formulation with
theta, x..
