[R] Games

[Silvano]

Hi,

I want to build the table of a football league with 11 
teams. All play together. So will 55 games.
Since there are an odd number of teams in each round a team 
will not play.
The games will be:

games = urnsamples(1:11, x = 
c('A','B','C','D','E','F','G','H','I','J','K'), size=2, 
replace=F,
ordered=FALSE)
games

As will be five games per round. How to build a table with 
all the championship rounds, automatically?
I thought about something like:

game1 = c(
sample(11,2)
sample(11,2)
sample(11,2)
sample(11,2)
sample(11,2)
)

but, isn't work very well.

Some suggestion?
