[R] Odp: Cutting a vector

[Dani Valverde]

Hello,
That's very useful. I think the cut() function is the key. However, in 
my real vector I have 13112 points. I would like the function to cut the 
vector every certain number of points (ie 4). Is there a way to specify 
this without the need of writing each cutting point? For example, I do 
not want to write breaks=c(4,8,12,...,13108, +Inf), but some expresion 
to avoid writing such a long argument.
Best regards,

Dani
