I guess that the 'names' are or could be represented by a 'factor' much
like the variable 'state' in the 'specific example' in
'An Introduction to R' Section 4
If the 'manual' have consulted was not 'An Introduction...', do as the
__posting guide__ suggests:
"Read at least the relevant section in An Introduction to R"
If that section (and the rest of 'An Intro...' for that matter) and the
help pages for the functions mentioned there do not answer your question,
it would probably help elicit a useful response to spell out how your
problem differs from those addressed therein.
