Dear Li
Not absolutely sure what you want to do but try
?aggregate
?by
?apply (or one of the other apply functions, possibly tapply

Hi everyone,
I'm new at R (although I'm a Stata user for some time and somehow
proficient in it) and I'm trying to use the 'diverse' R package to compute
a few diversity measures on a sample of firms for a period of about 10
years. I was wondering if you can give me some hints on how to best proceed
on using the 'diverse' package.
My sample has the following setup. It's comprised of a annual variable
number of firms which are identified by the companyid variable and the year
variable (unbalanced panel). In addition I also have a variable identifying
the worker, workerid. I then have a set of variables which i want to use as
the basis for calculating some of the measures in the 'diverse' package. An
example of the sample is as follows, using the gender variable (0 for male
and 1 for female) as the variable of interest:
companyid year workerid gender

Based on the 'diverse' need to calculate for each firm, for each year, for
instance the diversity(gender) measure. in Stata this would be obtained
just a issuing a by firm year command, but have no idea how to tackle this
is issue in R. Any ideas?
Best wishes,
Li
