The str() function will show you what is contained in m8. If you look at the manual page for Match:
> ?Match the section labeled "Value" gives more details on what results are returned by the Match() function. The print() and summary() functions usually show abbreviated results. In this case a list with 20 elements returned. If you don't know what a list is or how to extract things from a list, you will have to learn more about R.

Don't know anything about this in particular, but ?str, as in str(m8) is often useful in such situations. But hopefully you'll get a better, more specific answer.
