The gsubfn package can do quasi perl-style interpolation by

Assume that I have the dataframe "data1", which is listed at the end of this
message. I want count the number of lines that each person has for each
year. For example, the person with ID=213 has 15 entries (NinYear) for 1953.
The following bit of code calculates NinYear:

Choosing the model with minimum AIC is just one consideration that
might be used. If you look at books such as McQuarrie and Tsai
(1998), Regression and Time Series Model Selection, World Scientific,
you will find about 450 pages dealing mainly with the use of this and
similar criteria to select a
John,
Thank you for those references.

You might try the fgarch package

I would point out that the OP does not say that R is a part of the course, only
that they are using it to do some work. R may be a tool of choice not a
requirement and it is quite possible that the instructor does not know anything
about R.

Hi, get any of the manuals that are an introduction to R, e.g. from CRAN,
which describe the steps of how to start in R. You can google-search them
too. You will find what it takes to do that in there.
Hints:
1. R is object oriented. That is, your read.table command creates an object
Wdbc. It do
I have a function that could possibly generate warnings in a loop. What I want
is to report the warnings (warnings()) then clear out the last.warning object
so that if there is a call without warnings I will not see the previous warning.
Some example code:
generatewarning <- function(s)
{
I want to fit a model of Ar(1) mean equation and Arch(1) variance
equation(the equations are to the attached file) to 1000 observations.
How can I do that?

I am having serious trouble doing this homework. I am using R for doing the

Hi,
I have a huge table, approximatly 16,000 x 12,000, full of various integers.
Its a tab delimited file approx 400mb in size. R takes ages to read it in
(read.delim), and store it as a variable. My aim is to transpose the table,
however I am hesistate to do it incase it crashes my local server,
Dear Jorge
Thanks a lot.
