reach the end. So, I am not aware of the current state of consensus on
the issue.
It would help a lot if some current user could throw some light on this
issue of large data-sets in R.
Thanks in advance.

Thanks a lot for all the responses. The general drift of all the messages was
the suggestion to use some database management package that has a nice
interface with R; and most of the suggestions pointed in the direction of SQL.
I will look into the SQL package and start learning to use it along

As per Thomas' advice, I upgraded R by using update.packages() and got the

You have told us very little (please study the posting guide), not
including which version of R and how you installed it. Please try
reinstalling R, from the sources of R 2.5.0 RC if you can.

I am trying to maximise a complicated loglikelihood function with the optim
command. Is there some way to get to know the estiamtes at each iteration? When
I put control=list(trace=TRUE) as an option in optim, I just got the
initial and final values of the loglikelihood, number of iterations
of the
optimization.

Hi all,
I am trying to do a maximum likelihood estimation. In my likelihood function, I
have to evaluate a double integral of the bivariate normal density over a
subset of the points of the plane. For instance, if I denote by y the y
co-ordinate and by x, the x co-ordinate then the area over
Hi R users,
I have a couple of questions about some problems that I am facing with
regard to numerical integration and optimization of likelihood
functions. Let me provide a little background information: I am trying
to do maximum likelihood estimation of an econometric model that I have

seems you need to know more about it. The references on ?optim are too
advanced I guess, so you could start with Chapter 16 of MASS and its
references.
