[Rd] Documentation of addmargins

[SOEIRO Thomas]

Dear list,

There is a minor typo in addmargins (section Details):

- If the functions used to form margins are not commutative the result depends on the order in which margins are computed. Annotation of margins is done via naming the FUN list.
+ If the functions used to form margins are not commutative**add ':' or ', i.e.' here** the result depends on the order in which margins are computed. Annotation of margins is done via naming the FUN list.


I'm not sure if such minor things really need to be reported when they are noticed... Please let me know if not. Of course this is minor, but imho one of the strengths of R is also its documentation!

Best,

Thomas
