[R] Interweaving of two datasets

I have two datasets, the first has this shape (each word is a column)
Name address phone .. ..

The second one has the following shape
Name request

I need a contingency table with for example phone and request.


The people registered in these datasets are present in both datasets, BUT in
the first every record is a person, so every person is counted once and is 1
row, in the second every row is a request, so if a person has requested 1
thing this person is present only once, but is the person has requested 3
things, this person we'll be present 3 times.   

I now that to use access could be the solution, but in this moment the
computer expert give me data only as .xls/.csv data.

This creates the possibility of two different cross tab, I really need both,
the first has as total count the number of people
The second one has as total count the number of request
