Subject: [R] Help with tables in R

I am a new convert to R (from SAS).  I am a research scientist and most
of
my
use of SAS was in data analysis.  Recently, I have been wanting to use R
to
create a simple, reliable way to summarize a dataset of student
demographics
for a university.
The spreadsheet has a row for every student registered at the university
for
each term since fall 2010 with the following information about each
student
in columns:
Columns are the following: Term, College, Program, Campus, Gender,
Ethnicity, Age.

I have created summary tables in Excel using if/then type formulas to
select
data and count the number of female students in program A at location 3,
etc.

I have written some R code to create some figures that generally meet my
needs.
I would like to find a way to have R populate some tables with this type
of
information.

An example of my excel sheets are attached.


Any suggestions will be appreciated.
