[R] How do I construct a one matrix from another? (newbie)

[jonathanbriggs]

Apologies if this is an obvious question but I am teaching myself R and the
occasional push in the right direction is much appreciated?

I have a data.frame containing data that looks like this

CustID itemID
1        a
1        b
2        c
3        a
3        c

I want to assemble the vector of all the items bought by a particular
customer and can't quite see how to do it.

What is the best way to represent the answers for a single customer and by
all customers?

Thanks.
