Hello,
I just started using R last week and come from having used mostly SAS. I am
using it more for data mining and analysis rather than technical statistics
(just basic descriptive statistics). There are some things I want to get out
of the data but I think I am stuck because a lack of understanding the
language (and vectors too - i usually work in data frames). I have time
series data of funds, their cashflows, the type of cashflow (3 levels), the
specific date of the cashflow in addition to the fund year, fund size and
the classification of fund. I want to be able to group the funds together by
fund year and then group that subset by cashflow type or by fund size
(summing the cashflow by type by fund year and fund id). It would be nice to
see the distribution of fund sizes around specific vintage years as well as
the ratio of calls to fund size for a given time period.

Also, I would like to subtract the cashflow dates from the first cashflow
date by fund and then group the funds by their cashflow date bucket and see
how they compare to each other (aggregating over cashflow type, etc)

If there are good books that go more into the code with some illustrative
examples, I would appreciate the title and/or reference info. I have found
one online datamining source but it would be nice to get some more
resources. If you know of any R training centers or professionals in London
I can be put in touch with I would appreciate that too.

Thanks,
Samit
